26-9-2023 REVILLA, ARAGON - GREEN VEINED WHITE BUTTERFLY (Pieris napi)


 The green-veined white (Pieris napi) is a butterfly of the family Pieridae.

A circumboreal species widespread across Europe and Asia, including the Indian subcontinent, Japan, the Maghreb and North America. It is found in meadows, hedgerows and woodland glades but not as often in gardens and parks like its close relatives the large and small whites, for which it is often mistaken. Like other "white" butterflies, the sexes differ. The female has two spots on each forewing, the male only one. The veins on the wings of the female are usually more heavily marked. The underside hindwings are pale yellow with the veins highlighted by black scales giving a greenish tint, hence green-veined white. Unlike the large and small whites, it rarely chooses garden cabbages to lay its eggs on, preferring wild crucifers. Males emit a sex pheromone that is perceptible to humans, citral, the basic flavor-imparting component of lemon peel oil.

Some authors consider the mustard white and West Virginia white of North America to be conspecific with P. napi  or consider P. napi to be a superspecies. Despite this, the American butterflies, unlike P. napi, cannot successfully use garlic mustard as a host plant. Females will lay eggs on it, mistaking this non-native species for a compatible native mustard, resulting in the death of the offspring. Classification is also an issue concerning the European dark-veined white.

26-9-2023 REVILLA, ARAGON - SPECKLED WOOD BUTTERFLY (Pararge aegeria)


The speckled wood (Pararge aegeria) is a butterfly found in and on the borders of woodland areas throughout much of the Palearctic realm. The species is subdivided into multiple subspecies, including Pararge aegeria aegeria, Pararge aegeria tircis, Pararge aegeria oblita, and Pararge aegeria insula. The color of this butterfly varies between subspecies. The existence of these subspecies is due to variation in morphology down a gradient corresponding to a geographic cline. The background of the wings ranges from brown to orange, and the spots are either pale yellow, white, cream, or a tawny orange. The speckled wood feeds on a variety of grass species. The males of this species exhibit two types of mate locating behaviors: territorial defense and patrolling. The proportion of males exhibiting these two strategies changes based on ecological conditions. The monandrous female must choose which type of male can help her reproduce successfully. Her decision is heavily influenced by environmental conditions.



26-9-2023 REVILLA, ARAGON - LARGE SELF HEAL (Prunella grandiflora)


Low-growing plant with dark green foliage and purple-blue flowers. It's a perennial, but for some reason has a hard time coming through winter for us after its second year - so acts more like a biennial. Deadheading/cutting back may help to extend its lifespan.

25-9-2023 AINSA, ARAGON - EURASIAN EAGLE OWL (Bubo bubo)


 The Eurasian eagle-owl (Bubo bubo) is a species of eagle-owl that resides in much of Eurasia. It is also called the Uhu and it is occasionally abbreviated to just the eagle-owl in Europe. It is one of the largest species of owl, and females can grow to a total length of 75 cm (30 in), with a wingspan of 188 cm (6 ft 2 in), with males being slightly smaller. This bird has distinctive ear tufts, with upper parts that are mottled with darker blackish colouring and tawny. The wings and tail are barred. The underparts are a variably hued buff, streaked with darker colouring. The facial disc is not very defined and the orange eyes are distinctive.

Eurasian eagle-owls are found in many habitats, but are mostly birds of mountainous regions or other rocky areas, often those near varied woodland edge and shrubby areas with openings or wetlands to hunt a majority of their prey. Additionally, they inhabit coniferous forests, steppes, and other areas at varied elevations that are typically relatively remote. Eurasian eagle-owls are occasionally found amongst farmland and in park-like settings within European cities, even rarely within busier urban areas. The eagle-owl is mostly a nocturnal predator, hunting for a range of different prey species. Predominantly, their diet is composed of small mammals such as rodents and rabbits, but they also prey on larger mammals and birds of varying sizes. Other secondary prey can include reptiles, amphibians, fish, large insects and other assorted invertebrates. The species typically breeds on cliff ledges, in gullies, among rocks, or in other concealed locations. The nest is a scrape containing a clutch of 2 - 4 eggs typically, which are laid at intervals and hatch at different times. The female incubates the eggs and broods the young, and the male provides food for her, and when they hatch, for the nestlings, as well. Continuing parental care for the young is provided by both adults for about five months. At least 12 subspecies of the Eurasian eagle-owl are described.

25-9-2023 AINSA, ARAGON - SHORT TOED SNAKE EAGLE (Circaetus gallicus)

The short-toed snake eagle (Circaetus gallicus), also known as the short-toed eagle, is a medium-sized bird of prey in the family Accipitridae, which also includes many other diurnal raptors such as kites, buzzards and harriers. The genus name Circaetus is from the Ancient Greek kirkos, a type of hawk, and aetos, "eagle". The specific gallicus means "of Gallia".

These are relatively large snake eagles. Adults are 59 to 70 cm (23 to 28 in) long with a 162 to 195 cm (5 ft 4 in to 6 ft 5 in) wingspan and weigh 1.2–2.3 kg (2.6–5.1 lb), an average weight for the species is about 1.7 kg (3.7 lb). They can be recognised in the field by their predominantly white underside, the upper parts being greyish brown. The chin, throat and upper breast are a pale, earthy brown. The tail has 3 or 4 bars. Additional indications are an owl-like rounded head, brightly yellow eyes and lightly barred under wing.

The short-toed snake eagle spends more time on the wing than do most members of its genus. It favours soaring over hill slopes and hilltops on updraughts, and it does much of its hunting from this position at heights of up to 500 m (1,600 ft). When quartering open country it frequently hovers like a kestrel. When it soars it does so on flattish wings.

This is an Old World species found throughout the Mediterranean basin, into Russia and the Middle East, and parts of Western Asia, and in the Indian Subcontinent and also further east in some Indonesian islands.

Those present on the northern edge of the Mediterranean and other parts of Europe migrate mainly to sub-Saharan Africa north of the equator, leaving in September/October and returning in April/May.Populations are resident. In Europe, it is most numerous in Spain where it is fairly common but elsewhere it is rare in many parts of its range. A bird on the Isles of Scilly, Britain, in October 1999 was the first confirmed record for that country.

The short-toed snake eagle is found in open cultivated plains, arid stony deciduous scrub areas and foothills and semi-desert areas. It requires trees for nesting and open habitats, such as cultivations and grasslands for foraging.


 Its prey is mostly reptiles, mainly snakes, but also some lizards. Sometimes they become entangled with larger snakes and battle on the ground. Occasionally, they prey on small mammals up to the size of a rabbit, and rarely birds and large insects.

This eagle is generally very silent. On occasions, it emits a variety of musical whistling notes. When breeding, it lays only one egg. It can live up to 17 years.

The short-toed snake eagle has suffered a steep decline in numbers and range in Europe and is now rare and still decreasing in several countries due to changes in agriculture and land use. It needs protection. In the middle and far eastern part of its range, this species is not yet threatened.

25-9-2023 AINSA, ARAGON - MALLOW SKIPPER BUTTERFLY (Carcharodus alceae)

Carcharodus alceae has a wingspan of 28–32 mm. The background colour of the forewings is pinkish brown, with approximately square brown markings, short, white transverse stripes running from the edge and clear patches on the discal area. Hindwings are brownish or grey-brown, with some prominent brighter spots on the underside. Males are without hair tuft on forewings underside. Antennae have cherry brown tips.

The eggs are yellowish and hemispherical and the surface is covered with elongated warts, connected each other with low ribs. The egg has a prickly appearance. In the course of the development they turn red. The caterpillars can reach a length of about 23 millimetres (0.91 in). They are dark gray, covered with small white dots and short, white hairs. The head is black with yellow spots, separated by black stripes.


 This widespread and common species can be found from Western Europe to Central Asia e.g. in most of southern and central Europe, in northern Africa (Morocco east to Tunisia and Libya), in the Middle East, in Asia Minor, the Caucasus, in northern India, in the Middle and Central Asia, in the western Himalayas and in the south of Western Siberia. In Europe, the species occurs mainly in the Mediterranean area. In Germany, the regular distribution extends to Central Germany (north to the Kyffhäuser Mountains). Evidence in previously unpopulated areas of Central Europe clearly indicates that C. alceae is currently in a phase of spreading.

These butterflies prefer dry warm and stony areas, wasteland, warm ruderals and gardens at an elevation up to 1,100 metres (3,600 ft) above sea level. The altitudinal distribution of Carcharodus alceae in Bavaria extends from about 100 m to 600 m, the focus is in the Colline zone with an altitude distribution between 200 m and 500 m.

A wide range of grassland habitats and ruderal meadows with occurrences of mallow species serve as habitat for Carcharodus alceae. In Middle and Southern Franconian Jura, these are imperfections in limestone and sandy grasslands or ruderal embankments as well as other thermophilic ruderal meadows. Other habitats include fallow land, especially industrial wasteland, roadsides and arable fields that have been sown with seed mixtures, and oviposition also take place regularly in gardens and on the edge of vineyards. In limestone grasslands, especially locations with patchy and disturbed vegetation, such as limestone rubble areas, seams or marginal transition structures to fields are used. Numerous observations have been made in the last few years in freshly cleared limestone grasslands over open bare ground. At the latter there is temporarily an increased settlement of mallow species.

The powerfully flying imagos can evidently colonize newly created habitats very quickly. Often a single mallow plant is enough. In the Neumarkt / Oberpfalz district in Germany, for example, it has been possible to detect the species both as a butterfly and as a caterpillar in almost all of the larger grassland areas over the past ten years, albeit mostly only in low density. Although the imagos are very capable of flying and thus spreading rapidly, they are mostly observed in the vicinity of their larval habitats.

ARADOR, TERUEL - COMMON BLUE BUTTERFLY (Polyommatus icarus)


The common blue butterfly or European common blue (Polyommatus icarus) is a butterfly in the family Lycaenidae and subfamily Polyommatinae. The butterfly is found throughout the Palearctic and has been introduced to North America. Butterflies in the Polyommatinae are collectively called blues, from the coloring of the wings. Common blue males usually have wings that are blue above with a black-brown border and a white fringe. The females are usually brown above with a blue dusting and orange spots.



28-9-2023 LA PARDINA, ARAGON - CORN BUNTING (Emberiza calandra)


The corn bunting (Emberiza calandra) is a passerine bird in the bunting family Emberizidae, a group now separated by most modern authors from the finches, Fringillidae. This is a large bunting with heavily streaked buff-brown plumage. The sexes are similar but the male is slightly larger than the female. Its range extends from Western Europe and North Africa across to northwestern China.

This is an unusual bunting because the plumages of the sexes are similar in appearance, though the male is approximately 20% larger than the female. This large bulky bunting is 16–19 cm long, with a conspicuously dark eye and yellowish mandibles. Males lack any showy colours, especially on the head, which is otherwise typical of genus Emberiza. Both sexes look something like larks, being streaked grey-brown above with whitish underparts. The underparts are streaked over the flanks and breast, and the streaking forms gorget around the throat. The lesser wing coverts are distinctively dark and white-tipped. The tail is plain brown.

The song of the male is a repetitive metallic sound, usually likened to jangling keys, which is given from a low bush, fence post or telephone wires.

28-9-2023 PARADOR, TERUEL - COMMON BLUE BUTTERFLY (Polyommatus icarus)

The common blue butterfly or European common blue (Polyommatus icarus) is a butterfly in the family Lycaenidae and subfamily Polyommatinae. The butterfly is found throughout the Palearctic and has been introduced to North America. Butterflies in the Polyommatinae are collectively called blues, from the coloring of the wings. Common blue males usually have wings that are blue above with a black-brown border and a white fringe. The females are usually brown above with a blue dusting and orange spots.

The Common blue was elected as the national butterfly of Israel in 2023.

28-9-2023 PARADOR, TERUEL - ZILLA ORB WEAVER SPIDER (Zilla diodia)

Zilla diodia is an orb-weaver spider species found from Europe to Azerbaijan. This species was originally described by Charles Athanase Walckenaer in 1802 as Aranea diodia.

Zilla diodia build very fine, vertical orb webs with often more than 50 radii and sticky spiral loops. The radii in the webs of this species – unlike those in most other orb webs – are double stranded at the periphery of the web and single stranded near the centre, presumably as an adaptation to the different forces acting on the inner and outer part of the radii.


 

28-9-2023 PARADOR, TERUEL - GORSE ORB WEAVER SPIDER (Agalenatea redii)


Agalenatea redii is a species of 'orbweavers' belonging to the family Araneidae subfamily Araneinae.

The adult males of these spiders reach 4.6–6.2 millimetres (0.18–0.24 in) of length, while females are 6.5–10.3 millimetres (0.26–0.41 in) long. The coloration of the body is very variable. The basic color varies from light or dark brown to yellowish-orange. They usually show a dark longitudinal band in the middle of the abdomen, with some trasversal bands. Sometimes the opisthosoma has two large white spots or one dark brown light-edged spot on the back. Chelicerae and legs are brown. The whole body is densely hairy, especially in the anterior body section (prosoma). The thorax is relatively broad, pear-shaped. The abdomen (opisthosoma) is quite flat and wider than long.

28-9-2023 PARADOR, TERUEL - BATH WHITE BUTTERFLY (Pontia daplidice)


Pontia daplidice, the Bath white, is a small butterfly of the family Pieridae, the yellows and whites, which occurs in the Palearctic region. It is common in central and southern Europe, migrating northwards every summer, often reaching southern Scandinavia and sometimes southern England.

The Bath white is a small white butterfly with a wingspan of 45 to 50 mm. The underside of the hindwing has a pattern of greenish blotches, which is characteristic of the Bath whites and easily identifies it from other pierids.

Sexes can be differentiated by markings on the forewing. The male is differentiated from the female by the markings on the upperside of the forewing. The apex of the forewing is black with white spots and lines. There is a black spot at the end of the cell. In the case of the female, there is an additional discal spot in 1b. The female also has an obscure row of terminal and marginal spots on the upper hindwing.

28-9-2023 PARADOR, TERUEL - PANOPTES BLUE BUTTERFLY (Pseudophilotes panoptes)



Pseudophilotes panoptes, the Panoptes blue, is a butterfly of the family Lycaenidae. It is found on the Iberian Peninsula and in North Africa, including Morocco.

It is very like Pseudophilotes baton but without the reddish yellow anal spots. The wingspan is 18–22 mm. There are two generations per year with adults on wing from March to August.

The larvae feed on Thymus species.

28-9-2023 PARADOR, TERUEL - SOUTHERN GRIZZLED SKIPPER BUTTERFLY (Pyrgus malvoides)


 Pyrgus malvoides, the Southern Grizzled Skipper, is a species of skipper (family Hesperiidae).

The wingspan of this butterfly is 24–26 mm. 

Pyrgus malvoides is distributed from Portugal and Spain via southern and central France, southern Switzerland (south of the main Alpine ridge) and Austria (Vorarlberg, Tyrol) to Italy and Istria.

According to previous knowledge, Pyrgus malvoides colonizes various fresh and above all moist habitats in the Alps if these have structures that are favorable to the microclimate, such as open ground on gravel, rocks, obstructions from cattle kicking or erosion, etc. A syntopic occurrence with Pyrgus malvae could not be determined so far. Because of the identification problems in the field, no sucking plants were noted. It is assumed that there are no essential differences to Pyrgus malvae here.

The known altitudinal distribution extends from 800 m to about 2000 m in Bavaria. It is found up to heights of 2500 m in the central Alps.


Adults are on wing from April to September. In Bavaria Pyrgus malvoides flies in one generation from around mid-May to mid-July. A second or even third generation per year, as described e.g. in Italy, was not observed in Bavaria.

The larvae feed on Potentilla, Agrimonia and Fragaria species, but primarily Potentilla erecta. It is reported from Switzerland that the caterpillars have been found on various cinquefoil species (Potentilla neumanniana [= tabernaemontani], Potentilla pusilla, Potentilla erecta) and have eaten Fragaria vesca during breeding.

27-9-2023 PLANS, ARAGON - QUEEN OF SPAIN FRITILLARY BUTTERFLY (Issoria lathonia)

This species is present almost throughout the year, with three or four successive generations. The eggs are laid separately on the underside of the leaves of the host plant. The larval cycle is exceptionally short. The pupation takes place among the low vegetation, between a few leaves united by silk. This species may overwinter at all larval stages.

Adults are strong flyers and fly from March to October. The heat-dependent caterpillars feed on Viola species (wild pansy or heartsease (Viola tricolor), field pansy (Viola arvensis), Viola canina, Viola odorata, Viola calcarata, Viola lutea, Viola biflora), lucerne (Medicago sativa), borage (Borago officinalis), Anchusa, Rubus and Onobrychis species.

In the dry regions Issoria lathonia carries out a seasonal vertical migration between hardy evergreen shrubs and small trees of plains and mountain fir pines, where it remains in summer to descend in autumn at low altitude.

Issoria lathonia is a medium-sized butterfly with a wingspan of 38–46 millimetres (1.5–1.8 in). The wings show a deep orange-violet background, with rounded black spots arranged in regular rows and suffused with greenish gray in the females. The underside of the hindwings is decorated with large pearly nacreous spots and it is crossed by a postdiscal row of black eyespots with pearly pupils. Some pearly spots also appear at the apex of the forewings.

The caterpillar can reach a length of 35 millimetres (1.4 in). It is grayish brown, with black spots, and relatively short brown spines with white tip, and a double row of dorsal white streaks. The suspended chrysalis is dark brown, with a large white saddle-shaped stain and some smaller ones of the same color, resembling a bird's dropping.

The imago is loosely similar to Speyeria aglaja, Fabriciana adippe and Brenthis daphne, which have the same orange color on the upperside of the wings, but show different markings and spots. Moreover, the underside of the hindwings does not have the large pearly spots characteristic of the Queen of Spain fritillary.


This migratory species is widespread in most of Europe, in North Africa, Canary Islands, and in the eastern Palearctic realm (Central Asia, Himalayas, Baluchistan, and Western China). These butterflies live in open areas, in dry lawns, agricultural wastelands and in extensive crops at altitudes between sea level and 2700 m.

27-9-2023 PLANS, ARAGON - BEARDED VULTURE (Gypaetus barbatus)


The bearded vulture (Gypaetus barbatus), also known as the lammergeier and ossifrage, is a very large bird of prey and the only member of the genus Gypaetus. Traditionally considered an Old World vulture, it actually forms a separate minor lineage of Accipitridae together with the Egyptian vulture (Neophron percnopterus), its closest living relative. It is not much more closely related to the Old World vultures proper than to, for example, hawks, and differs from the former by its feathered neck. Although dissimilar, the Egyptian and bearded vulture each have a lozenge-shaped tail—unusual among birds of prey. It is vernacularly known as Homa, a divine bird in Iranian mythology.

The bearded vulture population is thought to be in decline; in 2004, it was classified on the IUCN Red List as least concern but has been listed as near threatened since 2014. It lives and breeds on crags in high mountains in southern Europe, East Africa, the Indian subcontinent, Tibet, and the Caucasus.Females lay one or two eggs in mid-winter that hatch at the beginning of spring. The bearded vulture is the only known vertebrate whose diet consists of 70–90% bone.

26-9-2023 MEDIANO, ARAGON - EUROPEAN STONECHAT (MALE) (Saxicola rubicola)

The European stonechat (Saxicola rubicola) is a small passerine bird that was formerly classed as a subspecies of the common stonechat. Long considered a member of the thrush family, Turdidae, genetic evidence has placed it and its relatives in the Old World flycatcher family, Muscicapidae.




26-9-2023 REVILLA, ARAGON - COMMON WALL LIZARD (Podarcis muralis)


Podarcis muralis (common wall lizard) is a species of lizard with a large distribution in Europe and well-established introduced populations in North America, where it is also called the European wall lizard. It can grow to about 20 cm (7.9 in) in total length. The animal has shown variation in the places it has been introduced to. Fossils have been found in a cave in Greece dating to the early part of the Holocene.

The common wall lizard is a small, thin lizard whose small scales are highly variable in colour and pattern. Its coloration is generally brownish or greyish, and may occasionally be tinged with green. In some individuals, the row of spots along their backs may form a line, while others may have a reticulated pattern with dark spots on the side and scattered white spots that can be blue in the shoulder region. The tail is brown, grey or rust in colour, and may also have light bars on the sides. The belly region has six rows of larger rectangular scales that are generally reddish, pink, or orangish. Common wall lizards may also have dark markings on the throat. This lizard has six distinct morphological forms which are identified by the colouration of its throat and underbelly. Three of these are pure morphs consisting only of solid colours on their scales: white, red (orange) or yellow, and three other morphs are distinguished by a combination of colours: white-yellow, white-red and yellow-red. 


26-9-2023 REVILLA, ARAGON - ROCK GRAYLING BUTTERFLY (Hipparchia alcyone)


Hipparchia hermione, the rock grayling, is a butterfly of the family Nymphalidae. The species can be found in Central Europe, Southern Europe, Eastern Europe, North Africa, Anatolia and the Caucasus.

The wingspan is 27–34 millimetres (1.1–1.3 in).The ground colour is dark brown. There is a white submarginal band, bordered with an interrupted fringe and a large black ocellus at the apex of the forewing. The hindwing has a small ocellus with a very discrete pupil

The underside of the forewing is similar: brown with a white submarginal band and the black ocellus with white pupil at the apex, while the hindwing is marbled with brown and white with a broad white band. No sexual dimorphism.

Similar to Hipparchia fagi, but on the underside the deep dark basal area of both wings contrasts much more sharply with the light band, and the latter, which is almost pure white on the hindwing, contrasts again conspicuously with the broad dark distal margin. The conspicuousness of the pattern on the underside of the hindwing is especially noticeable in the male, but even in the duller coloured female the band on the hindwing beneath is still quite distinct, although sparsely irrorated with black.

It is smaller than fagi.

26-9-2023 REVILLA, ARAGON - WALLCREEPER (Tichodroma muraria)


The wallcreeper (Tichodroma muraria) is a small passerine bird found throughout the high mountains of the Palearctic from southern Europe to central China. It is the only extant member of both the genus Tichodroma and the family Tichodromidae.

The wallcreeper is a 15.5–17-centimetre (6.1–6.7 in) long bird, with a mass of 17–19 grams (0.60–0.67 oz). Its plumage is primarily blue-grey, with darker flight and tail feathers. Its most striking plumage feature, though, are its extraordinary crimson wings. Largely hidden when the wings are folded, this bright colouring covers most of the covert feathers, and the basal half of the primaries and secondaries. The subspecies T. m. nepalensis is slightly darker than the nominate race.

The wallcreeper is an insectivore, feeding on terrestrial invertebrates—primarily insects and spiders—gleaned from rock faces. It sometimes also chases flying insects in short sallies from a rock wall perch. Feeding birds move across a cliff face in short flights and quick hops, often with their wings partially spread.

25-9-2023 AINSA, ARAGON - BEARDED VULTURE (Gypaetus barbatus)


The bearded vulture (Gypaetus barbatus), also known as the lammergeier and ossifrage, is a very large bird of prey and the only member of the genus Gypaetus. Traditionally considered an Old World vulture, it actually forms a separate minor lineage of Accipitridae together with the Egyptian vulture (Neophron percnopterus), its closest living relative. It is not much more closely related to the Old World vultures proper than to, for example, hawks, and differs from the former by its feathered neck. Although dissimilar, the Egyptian and bearded vulture each have a lozenge-shaped tail—unusual among birds of prey. It is vernacularly known as Homa, a divine bird in Iranian mythology.

The bearded vulture population is thought to be in decline; in 2004, it was classified on the IUCN Red List as least concern but has been listed as near threatened since 2014. It lives and breeds on crags in high mountains in southern Europe, East Africa, the Indian subcontinent, Tibet, and the Caucasus.Females lay one or two eggs in mid-winter that hatch at the beginning of spring. The bearded vulture is the only known vertebrate whose diet consists of 70–90% bone.

This bird is 94–125 cm (37–49 in) long with a wingspan of 2.31–2.83 m (7 ft 7 in – 9 ft 3 in). It weighs 4.5–7.8 kg (9.9–17.2 lb), with the nominate race averaging 6.21 kg (13.7 lb) and G. b. meridionalis of Africa averaging 5.7 kg (13 lb). In Eurasia, vultures found around the Himalayas tend to be slightly larger than those from other mountain ranges. Females are slightly larger than males. It is essentially unmistakable with other vultures or indeed other birds in flight due to its long, narrow wings, with the wing chord measuring 71.5–91 cm (28.1–35.8 in), and long, wedge-shaped tail, which measures 42.7–52 cm (16.8–20.5 in) in length. The tail is longer than the width of the wing. The tarsus is relatively small for the bird's size, at 8.8–10 cm (3.5–3.9 in). The proportions of the species have been compared to a falcon, scaled to an enormous size.

Unlike most vultures, the bearded vulture does not have a bald head. This species is relatively small-headed, although its neck is powerful and thick. It has a generally elongated, slender shape, sometimes appearing bulkier due to the often hunched back of these birds. The gait on the ground is waddling and the feet are large and powerful. The adult is mostly dark gray, rusty, and whitish in color. It is grey-blue to grey-black above. The creamy-coloured forehead contrasts against a black band across the eyes and lores and bristles under the chin, which form a black beard that give the species its English name. Bearded vultures are variably orange or rust of plumage on their head, breast, and leg feathers, but this is actually cosmetic. This colouration may come from dust-bathing, rubbing mud on its body, or drinking mineral-rich waters. The tail feathers and wings are gray. The juvenile bird is dark black-brown over most of the body, with a buff-brown breast and takes five years to reach full maturity. The bearded vulture is silent, apart from shrill whistles in their breeding displays and a falcon-like cheek-acheek call made around the nest.



25-9-2023 AINSA, ARAGON - MALLOW SKIPPER BUTTERFLY (Carcharodus alceae)


Carcharodus alceae, commnly known as the mallow skipper, is a species of butterfly of the family Hesperiidae.

Carcharodus alceae has a wingspan of 28–32 mm. The background colour of the forewings is pinkish brown, with approximately square brown markings, short, white transverse stripes running from the edge and clear patches on the discal area. Hindwings are brownish or grey-brown, with some prominent brighter spots on the underside. Males are without hair tuft on forewings underside. Antennae have cherry brown tips.

The eggs are yellowish and hemispherical and the surface is covered with elongated warts, connected each other with low ribs. The egg has a prickly appearance. In the course of the development they turn red. The caterpillars can reach a length of about 23 millimetres (0.91 in). They are dark gray, covered with small white dots and short, white hairs. The head is black with yellow spots, separated by black stripes. 

25-9-2023 LA PERDIDA, ARAGON - SCALLOPED OAK MOTH

The scalloped oak (Crocallis elinguaria) is a moth of the family Geometridae. The species was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae.

This common species can be found from Europe to eastern Siberia.

This species inhabits a wide range of habitats, including mixed and deciduous forests, bushes, heaths, scrub, hedgerows, bogs, parks and gardens.


 The wingspan is 32–46 mm. This is a distinctive species, usually with yellow-tan forewings with a broad orange-brown band and a pointed apex. Females are usually paler. There can be considerable variation, with the central band sometimes the same colour as the rest of the forewing, ranging from pale yellow to orange brown. Melanic forms are also known. There is always a blackish discal spot on the forewing in middle of band towards the costa. The thorax is hairy. The hindwings are plain whitish. Last instar caterpillars have a brownish or yellowish colouration. On the dorsum there is a dark brown line which is extended at the segment incisions. There are sometimes some dark spots or slashes on the sides. Characteristic are two small pointed warts on the eleventh segment. This species is rather similar to Crocallis albarracina. Prout describes some forma.

24-9-2023 CAMBRILS, TARRAGONA - YELLOW LEGGED GULL (Larus michahellis)

The breeding range is centred on the Mediterranean Sea. In North Africa, it is common in Morocco, Algeria and Tunisia and increasing in places. Recent breeding has occurred in Libya and Egypt. In the Middle East, a few breed in Israel, Palestine and Syria with larger numbers in Cyprus and Turkey. In Europe, there are colonies all along the Mediterranean coast, and also on the Atlantic islands and coasts north to Brittany and west to the Azores. It also breeds on the western side of the Black Sea; here it overlaps with the Caspian gull but there is a difference in habitat, with the yellow-legged gull preferring sea cliffs and the Caspian gull flatter shores. In recent decades birds have spread north into central and western Europe. One to four pairs have attempted to breed in southern England since 1995 (sometimes hybrid pairs with lesser black-backed gulls), though colonisation has been very slow.


Many birds remain in the same area all year round, but others migrate to spend the winter in mild areas of western Europe or head south as far as Senegal, Gambia and the Red Sea. There is also extensive northward post-breeding dispersal in the late summer, with numbers in southern England high from July to October.

Like most Larus gulls, they are omnivores and opportunistic foragers. They will scavenge on rubbish tips and elsewhere, as well as seeking suitable prey in fields or on the coast, or robbing smaller gulls and other seabirds of their catches. Although urban populations are generally opportunistic scavengers, they can shift to a predatory diet if necessary; this was observed during the lockdown of Italy in 2020, when the lack of food scraps led the yellow-legged gulls of Rome to take prey as large as rats and rock doves.

Atlantic gulls in Gibraltar have been observed and photographed picking and eating fruit from olive trees in flight. 

24-9-2023 CAMBRILS, TARRAGONA - YELLOW LEGGED GULL (JUVENILE) (Larus michahellis)

The yellow-legged gull (Larus michahellis) is a large gull found in Europe, the Middle East and North Africa, which has only recently achieved wide recognition as a distinct species. It was formerly treated as a subspecies of either the Caspian gull L. cachinnans, or more broadly as a subspecies of the herring gull L. argentatus. The genus name is from Latin Larus which appears to have referred to a gull or other large seabird, and the species name honours the German zoologist Karl Michahelles.


 It is now generally accepted that the yellow-legged gull is a full species, but until recently there was much disagreement. For example, British Birds magazine split the yellow-legged gull from the herring gull in 1993 but included the Caspian gull in the former, but the BOU in Great Britain retained the yellow-legged gull as a subspecies of the herring gull until 2007. DNA research, however, suggests that the yellow-legged gull is actually closest to the great black-backed gull L. marinus and the Armenian gull L. armenicus, while the Caspian gull is closer to the herring gull and the lesser black-backed gull L. fuscus, rather than being each other's closest relatives.

24-9-2023 CAMBRILS, TARRAGONA - MONK PARAKEET (Myiopsitta monachus)


The monk parakeet (Myiopsitta monachus), also known as the Quaker parrot, is a species of true parrot in the family Psittacidae. It is a small, bright-green parrot with a greyish breast and greenish-yellow abdomen. Its average lifespan is 20–30 years. It originates from the temperate to subtropical areas of South America. Self-sustaining feral populations occur in many places, mainly in areas of similar climate in North America and Europe.

In its native range, the monk parakeet is very common. In Argentina, Brazil, and Uruguay, monk parakeets are regarded as major agricultural pests (as noted by Charles Darwin, among others). Their population explosion in South American rural areas seems to be associated with the expansion of eucalyptus forestry for paper pulp production, which offers the bird the opportunity to build protected nests in artificial forests where ecological competition from other species is limited.

Self-sustaining feral populations have been recorded in several U.S. states and various regions of Europe (namely Spain, Portugal, Azores, Madeira, Balearic Islands, Gibraltar, France, Corsica, Malta, Cyprus, Sardinia, Italy, Greece, Romania, Channel Islands, Great Britain, Ireland, and Belgium), as well as in British Columbia, Canada, Brazil, Mexico, Chile, Israel, Bermuda, Bahamas, the United States, Cayman Islands, Puerto Rico, Easter Island, South Korea, Singapore, and Japan. As it is an open-woodlands species, it adapts readily to urban areas.

In areas where they have been introduced, some fear they will harm crops and native species, while others dispute evidence of harm caused by feral colonies, and oppose exterminating these birds, but local bans and eradication programs exist in some areas of the U.S. Outside the U.S., introduced populations do not appear to raise similar controversy, presumably because of smaller numbers of birds, or because their settlement in urban areas does not pose a threat to agricultural production. The U.K. appears to have changed its view on its feral populations and the Department for the Environment, Food and Rural Affairs is planning to remove monk parakeets from the wild, as it believes that they threaten local wildlife and crops. 



24-9-2023 REAL DE GANDIA, VALENCIA - LAMENTING GRASSHOPPER (Eyprepocnemis plorans)

The lamenting grasshopper (Eyprepocnemis plorans) has a name that sounds like they spend most of their time wondering about the love that never was. Instead, this insect is known to have a number of different forms, known as polymorphs, given its extra chromosomes. It is known for being a nervous species and also particularly good at flying.

23-9-2023 MONTE CORONA, VALENCIA - SPECKLED FOOTMAN MOTH (Coscinia cribraria)

Coscinia cribraria, the speckled footman, is a moth of the family Erebidae. The species was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae. It is found in Europe except the most northern parts; also in north-western Africa, Kazakhstan, Siberia, Mongolia, north-western and north-eastern China.

The wingspan is 30–35 mm. The moth flies from July to August depending on the location.

The larvae feed on various herbaceous plants, including Festuca, Calluna vulgaris and Plantago lanceolata. 

23-9-2023 MONTE CORONA, VALENCIA - HOARY FOOTMAN MOTH (Eilema caniola)


Eilema caniola, the hoary footman, is a moth of the family Erebidae. The species was first described by Jacob Hübner in 1808.

This species can be found in North Africa, in western and southern Europe, in eastern Europe up to south-western Russia, in the Near East, in the eastern Palearctic realm, and in the Oriental realm. These thermophilic moths usually occur in urban areas and as a caterpillar on old walls, roofs, shingle beaches, and rocky areas.

The wingspan is 28–35 mm. It is almost the same in colouring as Eilema griseola and Eilema lurideola but the forewings are much smaller, the outer margin is oblique, only slightly excurved; the colour is much lighter, more yellowish grey, so that the pale yellow costal stripe is less prominent. Hindwings are very pale, scarcely darker at the costal margin, with the apex much more pointed than in the two species mentioned, with which it might be confounded.

23-9-2023 MONTE CORONA, VALENCIA - HALF EDGED WALL JUMPING SPIDER (Menemerus semilimbatus)


 Menemerus semilimbatus are about 6.5–8.4 millimetres (0.26–0.33 in) long, the male being slightly smaller than the female. These fairly big jumping spiders are dorso-ventrally flattened and are covered with short dense, grayish-white hairs, with hairy whitish palps and a white band on the side margins of the carapace, showing also a small white, triangular marking in the middle. The eyes are large and forward-facing. The legs are light brown with darker rings and patches, while the abdomen is dorsally yellowish or grayish, with a characteristic pattern of several bright V-shaped markings. The females show a notch at the posterior edge of the epigyne and two oval depressions in the anterior half.
