28-8-2024 MARJAL DE LA SAFOR GANDIA, VALENCIA - EURASIAN HOOPOE (Upupa epops)

The Eurasian hoopoe (Upupa epops ) is the most widespread species of the genus Upupa. It is a distinctive cinnamon coloured bird with black and white wings, a tall erectile crest, a broad white band across a black tail, and a long narrow downcurved bill. Its call is a soft "oop-oop-oop". It is native to Europe, Asia and the northern half of Africa. It is migratory in the northern part of its range. It spends most of the time on the ground probing for grubs and insects. The clutch of seven to eight eggs is laid in an existing cavity. The eggs are incubated by the female and hatch asynchronously. Some ornithologists treat the African and Madagascar hoopoes as subspecies of the Eurasian hoopoe.

28-8-2024 MARJAL DE LA SAFOR GANDIA, VALENCIA - PURPLE LOOSESTRIFE (Lythrum salicaria)

Lythrum salicaria or purple loosestrife is a flowering plant belonging to the family Lythraceae. It should not be confused with other plants sharing the name loosestrife that are members of the family Primulaceae. Other names include spiked loosestrife and purple Lythrum. This herbaceous perennial is native to Europe and Asia, and possibly Australia.

It has been used as an astringent medicinal herb to treat diarrhea and dysentery; it is considered safe to use for all ages, including babies. It is also cultivated as an ornamental plant in gardens, and is particularly associated with damp, poorly drained locations such as marshes, bogs and watersides. However, it will tolerate drier conditions.

28-8-2024 MARJAL DE LA SAFOR GANDIA, VALENCIA - VIOLET DROPWING DRAGONFLY (MALE) (Trithemis annulata)


Trithemis annulata, commonly known as the violet dropwing, violet-marked darter, purple-blushed darter, or plum-coloured dropwing, is a species of dragonfly in the family Libellulidae. It is found in most of Africa, the Middle East, and southern Europe. These dragonflies are called dropwings because of their habit of immediately lowering their wings after landing on a perch. Males of this species are violet-red with red veins in the wings, while females are yellow and brown. Both sexes have red eyes.

Trithemis annulata is a robust medium-sized species with a wingspan of 60 mm (2.4 in). The mature male has a dark red head and a yellow labium with a brown central spot. The eyes are red with white spots on the rear edge, and the frons is dark metallic purplish-red. The prothorax is violet with slightly darker longitudinal stripes. The membranous wings have distinctive red veins, the pterostigma is orange-brown, and there is a large orange-brown splash at the base of the hind wings. The abdomen is fairly broad and is pinkish-violet, with purple markings on the top of each segment and blackish markings on the terminal three segments. Females are a similar size to males, but the thorax is brownish, and the abdomen is yellow with dark brown markings. The wings of females lack the red veins of males but have similar orange-brown patches. It is very similar in appearance to the red-veined dropwing (Trithemis arteriosa), but that species has a more slender abdomen and a wedge-shaped black area on either side of the tip of the abdomen.

26-8-2024 MONTE CORONA, VALENCIA - VESTAL MOTH (Rhodometra sacraria)


Rhodometra sacraria, the vestal, is a moth of the family Geometridae. The species was first described by Carl Linnaeus in his 1767 12th edition of Systema Naturae.

It can be found throughout Europe, in the Near East, in North Africa, in the Afrotropical realm and in large parts of Asia. It is also found in South America (Chile and Argentina).

Rhodometra sacraria inhabits meadows, forest clearing, paths, gardens and urban environments.

Rhodometra sacraria has a wingspan reaching 22–28 mm, while the length of the forewings is 12–14 mm. The late generations are smaller and the wingspan has an average of 16–26 mm. These moths are easily distinguishable from the mahogany or pink stripe, located on yellowish or cream background, crossing diagonally the dorsal sides of the upperwings from the posterior margin up to the apex. Discal spots are usually present and have the same colour as the postmedial line.


The dorsal sides of the hindwings are whitish and unmarked. The fringes on the wings are mostly in the basic colour. The abdomen is pure white. Head and thorax are straw yellow. In males the antennae are bipectinated to three-fourths length. The hind tibiae bear two pairs of spurs.

The intensity and the extent of the pink pigmentation is rather variable, depending on the seasonal temperature in the development of the pupae.

Usually these moths rest with a tent-like posture on twigs and herbs, with the wings parallel to each other. They fly from April to October in the Northern Hemisphere They are nocturnal, attracted to light and migrant. These moths breed in North Africa and in southern Europe, since they require constant warmth. The eggs are relatively long, yellowish, with distinct red spots.

The caterpillars mimic twigs and therefore they are quite difficult to locate. They are slender and reach a length of about 25 millimetres. The basic colour is pale brown or green, with a whitish underside. The green forms usually show a dark brown or reddish irregular stripe on the back. The head is reddish brown and relatively small.

These caterpillars feed on knotgrass, dock, Anthemis, Emex, Oxygonum, Persicaria, Rhus and other low growing plants. The pupa can reach a length of 9.2 mm and a diameter of about 2.7 mm. It is yellowish brown coloured, with dark spots.

19-3-2016 MONTE CORONA, VALENCIA - EURASIAN BLACKCAP (FEMALE)

The Eurasian blackcap (Sylvia atricapilla) is a common and widespread warbler that breeds in much of Europe, western Asia, and northwestern Africa. Its rich and varied song has led to the blackcap being described as the "mock nightingale" and it has been featured in literature, films, and music.

The Eurasian blackcap is mainly grey in color with distinct male and female plumages. The adult male has olive-grey upperparts, other than a paler grey nape and a neat black cap on the head. The underparts are light grey, becoming silvery white on the chin, throat, and upper breast. The tail is dark grey, with an olive tint to the outer edge of each feather. The bill and long legs are grey, and the iris is reddish brown. The female resembles the male but has a reddish-brown cap and a slightly browner tone to the grey of the upperparts. Juveniles are similar to the female, but their upperparts have a slight rufous tinge, and the breast and flanks have a more olive tone; young males have darker brown cap than their female counterparts.

Eurasian blackcaps breed in much of Europe, western Asia, and northwestern Africa. They are partial migrants; birds from the colder areas of their range winter in northwestern Europe, around the Mediterranean, and in tropical Africa. Some German birds have adapted to spending the winter in gardens in Great Britain and Ireland. Eurasian blackcaps breed in mature deciduous woodlands, with good scrub cover below the trees, and may also be found in parks, large gardens, and overgrown hedges. The preferred winter habitat around the Mediterranean is scrub and olive orchards, while in Africa they occur in cultivated land, acacia scrub, mangroves, and forest.


Eurasian blackcaps are very active birds. They are usually found singly but may form loose groups during migration. They feed by the day mainly picking prey off foliage and twigs, but may occasionally hover, flycatch or feed on the ground. Blackcaps eat a wide range of small fruit and squeeze out any seeds on a branch before consuming the pulp. They defend good winter food sources, and at garden feeding stations they don't hesitate to repel competitors as large as starlings and blackbirds. Eurasian blackcaps are known for their beautiful loud song. The males' song is a rich musical warbling, often ending in a loud high-pitched crescendo, which is given in bursts of up to 30 seconds. In some geographically isolated areas, such as islands, peninsulas, and valleys in the Alps, males sing a simpler fluting song. The main call of Eurasian blackcaps is a hard 'tac-tac', like stones knocking together, and other vocalizations include a squeaking sweet alarm, and a low-pitched trill. Blackcaps may sometimes mimic the song of other birds, especially preferring to copy the garden warbler and the common nightingale.

13-11-2016 INWA, MYANMAR - PIED BUSH CHAT (MALE) (Saxicola caprata)

The pied bush chat (Saxicola caprata ) is a small passerine bird found ranging from West Asia and Central Asia to the Indian subcontinent and Southeast Asia. About sixteen subspecies are recognized through its wide range with many island forms. It is a familiar bird of countryside and open scrub or grassland where it is found perched at the top of short thorn trees or other shrubs, looking out for insect prey. They pick up insects mainly from the ground, and were, like other chats, placed in the thrush family Turdidae, but are now considered as Old World flycatchers.
They nest in cavities in stone walls or in holes in an embankment, lining the nest with grass and animal hair. The males are black with white shoulder and vent patches whose extent varies among populations. Females are predominantly brownish while juveniles are speckled. 


Among the Toda people in the Nilgiris, the pied bushchat or kāŗpiłc, is a bird of omen and the origin of its white wing patches is described in a story of a dairy priest Piu.f who in the ritual of churning milk forgot to remove the churning stick before fetching water from a stream. The bird attempted to obstruct him by blocking his path but he disregarded it and flicked off butter from his hands. The white spots remained but Piu.f met his death. The Kotas of the Nilgiris have an origin story to explain the sexual dimorphism of the pied bushchat but they consider the "karyvaky" bird to be one that foretells good omen. The Kalam people of Papua New Guinea consider the birds as messengers.

The pied bush chat is a resident breeder in tropical southern Asia from the Greater Middle East through the Indian subcontinent eastwards to Indonesia. They colonized Papua New Guinea around 1950. It is found in open habitats including scrub, grassland and cultivation.


Some populations are partially migratory. A ringed individual of subspecies rossorum has been recovered from Israel. The populations in India also appear to show seasonal movements but the patterns are unclear. Subspecies bicolor is found in peninsular India in winter. In Karwar on the western coast, it is said to appear in October and stay till May but not seen during the rainy season. Said to be absent in the Baroda district of Gujarat from April to September. Claud Buchanan Ticehurst noted that it was a summer visitor to Baluchistan leaving in October and further that the birds from Baluchistan were indistinguishable from rossorum of Turkestan.

24-8-2024 RIO SERPIS GANDIA, VALENCIA - EURASIAN COLLARED DOVE (Streptopelia decaocto)

 

The Eurasian collared dove (Streptopelia decaocto) is a dove species native to Europe and Asia. During the 20th century, the Eurasian collared dove spectacularly expanded its range from the Middle East to right across Europe. Accidentally introduced in 1974 into the Bahamas, this pale chunky bird soon spread to the mainland in Florida. A relative of the mourning dove, its name comes from its black half-collar around its neck.

The Eurasian collared dove is grey-buff to pinkish-grey overall, a little darker above than below, with a blue-grey underwing patch. The tail feathers are grey-buff above, and dark grey and tipped white below; the outer tail feathers are also tipped whitish above. It has a black half-collar edged with white on its nape. The short legs are red and the bill is black. The iris is red, but from a distance, the eyes appear to be black, as the pupil is relatively large and only a narrow rim of reddish-brown iris can be seen around the black pupil. The eye is surrounded by a small area of bare skin, which is either white or yellow. The two sexes are virtually indistinguishable; juveniles differ in having a poorly developed collar, and a brown iris.

24-8-2024 RIO SERPIS GANDIA, VALENCIA - EURASIAN BLACKBIRD (FEMALE) (Turdus merula)


The Common blackbird (Turdus merula) is a species of true thrush. It is also called the Eurasian blackbird (especially in North America, to distinguish it from the unrelated New World blackbirds), or simply the blackbird where this does not lead to confusion with a similar-looking local species. This common and conspicuous species has given rise to a number of literary and cultural references, frequently related to its song.

24-8-2024 RIO SERPIS GANDIA, VALENCIA - NOMAD DRAGONFLY (MALE) (Sympetrum fonscolombii)


The red-veined darter or nomad (Sympetrum fonscolombii) is a dragonfly of the genus Sympetrum.

Sympetrum fonscolombii was named under the protonym Libellula fonscolombii by the Belgian entomologist Edmond de Sélys Longchamps, in 1840, in honor of the French entomologist Étienne of Fonscolombe (hence the species name). Its name is sometimes spelt fonscolombei instead of fonscolombii but Askew (2004) gives the latter as the correct spelling.

Sympetrum fonscolombii can reach a body length of 38–40 millimetres (1.5–1.6 in). This species is similar to other Sympetrum species but a good view with binoculars should give a positive identification, especially with a male.

Males have a red abdomen, redder than many other Sympetrum species. The frons and the thorax are red-brown. The eyes are brown above and blue/grey below. The wings have red veins and the wing bases of the hind-wings are yellow. The pterostigma is pale yellow with a border of black veins.

Female are similar but the abdomen is ochre yellow, not red, with two black lines along each side. The wings have yellow veins at the costa, leading edge and base, not red veins as found in the males. The legs of both sexes are mostly black with some yellow.

Immature males are like females but often with more red and a single line along each side of the abdomen.

Male S. fonscolombii can be mistaken for Crocothemis erythraea as both are very red dragonflies with yellow bases to the wings, red veins and pale pterostigma. However C. erythraea has no black on the legs, a broader body and no black on the head. Also C. erythraea females do not oviposit in tandem. The gestalt image of these two species is different and with some experience are easy to tell apart.

24-8-2024 RIO SERPIS GANDIA, VALENCIA - SILK FLOSS TREE (Ceiba speciosa)

Ceiba speciosa, the floss silk tree (formerly Chorisia speciosa), is a species of deciduous tree that is native to the tropical and subtropical forests of South America. It has several local common names, such as palo borracho (in Spanish literally "drunken stick"), or árbol del puente, samu'ũ (in Guarani), or paineira (in Brazilian Portuguese). In Bolivia, it is called toborochi, meaning "tree of refuge" or "sheltering tree". In the USA it often is called the silk floss tree. It belongs to the same family as the baobab; the species Bombax ceiba; and other kapok trees. Another tree of the same genus, Ceiba chodatii, is often referred to by the same common names.

The natural habitat of the floss silk tree is in the northeast of Argentina, east of Bolivia, Paraguay, Uruguay, and southern Brazil. It is resistant to drought and moderate cold. It grows fast in spurts when water is abundant, and sometimes reaches more than 25 metres (82 ft) in height. Its trunk is bottle-shaped, generally bulging in its lower third, measuring up to 2 metres (7 ft) in girth. The trunk is studded with thick, sharp conical prickles that deter wild animals from climbing the trees. In younger trees, the trunk is green due to its high chlorophyll content, which makes it capable of performing photosynthesis when leaves are absent; with age it turns to gray.



The branches tend to be horizontal and also are covered with prickles. The leaves are composed of five to seven long leaflets. The flowers are creamy-whitish in the center and pink toward the tips of their five petals. They measure 10 to 15 centimetres (4 to 6 in) in diameter and their shape is superficially similar to hibiscus flowers. Their nectar is known to attract insect pollinators and hummingbirds. C. speciosa flowers are in bloom between February and May (in its native Southern Hemisphere), but it may bloom at other times of the year, even as late as November in Florida. The flowers of the related C. chodatii are similar in form and size, but their color goes from creamy white centers to yellow tips. As a deciduous tree, it is completely bare of leaves and flowers during the winter months, especially when growing outside of its native South American habitat.

24-8-2024 RIO SERPIS GANDIA, VALENCIA - LONG SKIMMER DRAGONFLY (MALE) (Orthetrum trinacria)


Orthetrum trinacria, the Long Skimmer, is a species of dragonfly in the family Libellulidae.

23-8-2024 MONTE CORONA, VALENCIA - KIRBY'S DROPWING DRAGONFLY (MALE) (Trithemis kirbyi)


Trithemis kirbyi, also known as the Kirby's dropwing, orange-winged dropwing, or scarlet rock glider is a species of dragonfly in the family Libellulidae.

It is found in Algeria, Angola, Benin, Botswana, Burkina Faso, Chad, Comoros, the Democratic Republic of the Congo, Ivory Coast, Egypt, Ethiopia, Gambia, Ghana, Guinea, Kenya, Liberia, Madagascar, Malawi, Morocco, Mozambique, Namibia, Nigeria, Senegal, Somalia, South Africa, Sudan, Tanzania, Togo, Uganda, Western Sahara, Zambia, Zimbabwe, and possibly Burundi. It is also present in southern Europe, the Arabian Peninsula, the Indian Ocean Islands and South Asia to India.

Since 2003 this African tropical dragonfly has been colonizing Europe helped by a widespread increase in temperatures. It is now breeding successfully in Spain, Portugal and France.

The adult male abdomen measures 21–24 mm and hind wing 24–27 mm. Female abdomen measures 23 mm and hind wing 26–30 mm. The male is a medium-sized scarlet dragonfly with a broad reddish amber patch on the base of transparent wings. The female is similar to the male, but duller in color. Its natural habitats are subtropical or tropical streams and rivers. It breeds in marshes, ponds, and lakes, and prefers to perch on exposed rocks, dry areas, and boulders in riverbeds.

23-8-2024 MONTE CORONA, VALENCIA - MEDITERRANEAN MANTIS (OOTHECA) (Iris oratoria)


 n ootheca /oʊ.əˈθiːkə/ (pl.: oothecae /oʊ.əˈθiːsiː/) is a type of egg capsule made by any member of a variety of species including mollusks (such as Turbinella laevigata), mantises, and cockroaches.

The word is a Latinized combination of oo-, meaning "egg", from the Greek word ōon (cf. Latin ovum), and theca, meaning a "cover" or "container", from the Greek theke. Ootheke is Greek for ovary.

Oothecae are made up of structural proteins and tanning agents that cause the protein to harden around the eggs, providing protection and stability. The production of ootheca convergently evolved across numerous insect species due to a selection for protection from parasites and other forms of predation, as the complex structure of the shell casing provides an evolutionary reproductive advantage (although the fitness and lifespan also depend on other factors such as the temperature of the incubating ootheca).  Oothecae are most notably found in the orders Blattodea (Cockroaches) and Mantodea (Praying mantids), as well as in the subfamilies Cassidinae (Coleoptera) and Korinninae (Phasmatodea).

The ootheca protects the eggs from microorganisms, parasitoids, predators, and weather; the ootheca maintains a stable water balance through variation in its surface, as it is porous in dry climates to protect against desiccation, and smooth in wet climates to protect against oversaturation. Its composition and appearance vary depending on species and environment.
