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.

21-8-2024 SOLLANA, VALENCIA - BLACK WINGED STILT (Himantopus himantopus)


Black-winged stilts (Himantopus himantopus) are very long-legged wading birds. They are found in both warm and hot climates, feed on small aquatic creatures, and nest on the ground surface in small colonies.

Adult Black-winged stilts have long, pink legs, and a long, rather thin black bill. They are generally black above and white below, with a white head and neck. Males have a black back, often with a greenish gloss or sheen. Females' backs have a brownish hue, contrasting with the black remiges. In populations where the top of the head is normally white (at least in winter), females tend to have less black on the head and neck the entire year round, while males often have much more black, particularly in summer. This difference is not clear-cut, however, and males usually grow all-white head feathers in winter. Immature birds are grey, instead of black, and have a markedly sandy hue on their wings, with light feather fringes appearing as a whitish line in flight.

21-8-2024 SOLLANA, VALENCIA - NOMAD DRAGONFLY (FEMALE) (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.

21-8-2024 SOLLANA, VALENCIA - SQUACCO HERON (Ardeola ralloides)


The squacco heron is a migrant, wintering in Africa. It is rare north of its breeding range. The species has been recorded in Fernando de Noronha islands, and more rarely in mainland South America, as a vagrant. This is a stocky species with a short neck, short thick bill and buff-brown back. In summer, adults have long neck feathers. Its appearance is transformed in flight, when it looks very white due to the colour of the wings.

The squacco heron's breeding habitat is marshy wetlands in warm countries. The birds nest in small colonies, often with other wading birds, usually on platforms of sticks in trees or shrubs. Three to four eggs are laid. They feed on fish, frogs and insects.

21-8-2024 RACO DE OLLA, VALENCIA - COMMON SHELDUCK (JUVENILE) (Tadorna tadorna)

The common shelduck (Tadorna tadorna ) is a waterfowl species of the shelduck genus, Tadorna. It is widespread and common in the Euro-Siberian region of the Palearctic, mainly breeding in temperate and wintering in subtropical regions; in winter, it can also be found in the Maghreb.

Fossil bones from Dorkovo (Bulgaria) described as Balcanas pliocaenica may actually belong to this species. More likely, they are an extinct species of Tadorna (if not a distinct genus) due to their Early Pliocene age; the present species is not unequivocally attested from the fossil record until some 2–3 million years later (Late Pliocene/Early Pleistocene).

The common shelduck resembles a small short-necked goose in size and shape. It is a striking bird, with a reddish-pink bill, pink feet, a white body with chestnut patches and a black belly, and a dark green head and neck. The wing coverts are white, the primary remiges black, and the secondaries green (only showing in flight) and chestnut. The underwings are almost entirely white. Sexes are similar, but the female is smaller, with some white facial markings, while the male is particularly crisply coloured in the breeding season, his bill bright red and bearing a prominent knob at the forehead.


Ducklings are white, with black cap, hindneck and wing and back patches. Juveniles are similarly coloured, greyish above and mostly white below, but already have the adult's wing pattern.

The call is a loud honk.

Moulting flocks can be very large (100,000 on the Wadden Sea), since most pairs leave their partially grown young in a crèche with just one or two adults.

This species is mainly associated with lakes and rivers in open country, breeding in rabbit burrows, tree holes, haystacks or similar. In winter it is common on suitable estuaries and tidal mudflats as well.

This bird is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies.

The young will dive under water to avoid predators and the adults will fly away from them to act as a decoy.

20-8-2024 MONTE CORONA, VALENCIA - PYRALID SNOUT MOTH ( Bostra obsoletalis)


Bostra obsoletalis is a species of moth in the family Pyralidae described by Josef Johann Mann in 1864. It is found in southern Europe, Yemen, Sudan, the Palestinian territories, Tunisia and Morocco.

The wingspan is 14–15 mm. Adults are on wing from June to August.

Common name is Asopie de Bursa.

Habitat is Phrygana, fields.

20-8-2024 MONTE CORONA, VALENCIA - CASE BEARING LEAF BEETLE (Subfamily Cryptocephalinae)


The Cryptocephalinae are a subfamily of the leaf beetles (Chrysomelidae), and belong to the group of case-bearing leaf beetles called the Camptosomata. The cases are made from the feces of larvae, passed from one instar to the next, and ultimately serves as a pupation chamber.


The tribes Fulcidacini and Clytrini were formerly considered subfamilies of their own, and are presently treated only as tribes. Species in at least 14 genera of Clytrini and Cryptocephalini are myrmecophilous, living with ants. Most species exhibit polyphagy but there are patterns of constraints with certain plant lineages.

19-8-2024 MONTE CORONA, VALENCIA - EPAULET SKIMMER DRAGONFLY (FEMALE) (Orthetrum chrysostigma)


Orthetrum chrysostigma, the epaulet skimmer, is a species of dragonfly in the family Libellulidae. It is found in Algeria, Angola, Benin, Botswana, Burkina Faso, Cameroon, Central African Republic, Chad, the Democratic Republic of the Congo, Ivory Coast, Egypt, Equatorial Guinea, Ethiopia, Gambia, Ghana, Guinea, Kenya, Liberia, Libya, Malawi, Mali, Mauritania, Morocco, Mozambique, Namibia, Niger, Nigeria, Senegal, Sierra Leone, Somalia, South Africa, Sudan, Tanzania, Togo, Uganda, Zambia, Zimbabwe, and possibly Burundi as well as Canary Islands, Israel, and Portugal. It was recorded in the Maltese Islands in 2010. One was also spotted in Tel Aviv, Israel in August 2022.

Its natural habitats are subtropical or tropical moist lowland forests, dry savanna, moist savanna, subtropical or tropical dry shrubland, subtropical or tropical moist shrubland, rivers, intermittent rivers, shrub-dominated wetlands, swamps, freshwater lakes, intermittent freshwater lakes, freshwater marshes, intermittent freshwater marshes, and freshwater springs. The adults prey on various flying insects. The bodies of adult males are blue, and those of young and females are yellow and brown.

18-8-2024 MONTE CORONA, VALENCIA - PEARL MOTH (Dolicharthria bruguieralis)


Dolicharthria bruguieralis is a species of moth in the family Crambidae. It is found from France, Portugal, Spain, Italy, Croatia, Romania, Bulgaria, the Republic of Macedonia, Albania, Greece and Turkey, east to Japan and Taiwan. It is also found in Africa, including Morocco, Algeria and South Africa.

The wingspan is about 17 millimetres (0.67 in).

It is so called on account of its pearly color.

18-8-2024 CREU DE LONGA, ALBUFERA - LITTLE EGRET (Egretta garzetta)

The Little Egret is a small white heron with attractive white plumes on crest, back and chest, black legs and bill and yellow feet. It first appeared in the UK in significant numbers in 1989 and first bred in Dorset in 1996. Its arrival followed naturally from a range expansion into western and northern France in previous decades. It is now at home on numerous south coast sites, both as a breeding species and as a winter visitor.

With its yellow feet, which are used to flush prey when feeding in shallow water, the Little Egret is a distinctive member of the heron family.

Little Egrets first bred in Britain in 1996 and since then have successfully colonised much of southern Britain and Ireland. Most of the breeding colonies have been established within existing Grey Heron colonies, the two species nesting alongside one another.

The winter distribution is also currently restricted to the southern half of Britain & Ireland, despite the fact that young birds are known to move some distance from their natal site.

18-8-2024 CREU DE LONGA, ALBUFERA - ZITTING CISTICOLA (Cisticola juncidis)

The zitting cisticola or streaked fantail warbler (Cisticola juncidis ) is a widely distributed Old World warbler whose breeding range includes southern Europe, Africa (outside the deserts and rainforest), and southern Asia down to northern Australia. A small bird found mainly in grasslands, it is best identified by its rufous rump; as well, it lacks any gold on the collar and the brownish tail is tipped with white. During the breeding season, males have a zigzagging flight display accompanied by regular "zitting" calls that have been likened to repeated snips of a scissor. They build their pouch nest suspended within a clump of grass.

The zitting cisticola is 10 to 12 cm (3.9 to 4.7 in) in length. It is brown above, heavily streaked with black markings. The underparts are whitish, and the tail is broad, white-tipped and flicked frequently, giving rise to the alternative name for the species. The adult males have less crown streaking and more back marking than the females, but there are no great difference between the sexes or the eighteen geographical races. The absence of a nuchal collar separate it from the golden-headed cisticola (Cisticola exilis ). In the non-breeding season, they tend to skulk within the grass and can be hard to spot.

This species is found mainly in grassland habitats, often near water. Most populations are resident, but some East Asian populations migrate south to warmer areas in winter. In the Himalayas, they ascend to about 1,900 m (6,200 ft) during summer but are below 1,300 m (4,300 ft) in the winter. This species is a rare vagrant to northern Europe, mostly as a spring overshoot. Its European range is generally expanding, although northern populations are especially susceptible to hard winters.

Zitting cisticolas are very small insectivorous birds, sometimes found in small groups. The breeding season is associated with the rains. Two broods a year occur in many regions. Males are generally polygynous, but some are monogamous. The male builds the initial nest structure deep in the grasses, and invites females using a special display. Females that accept the male complete the nest. The nest is made by binding living leaves into the soft fabric of felted plant-down, cobwebs, and grass. The zitting cisticola's nest is a cup shape with a canopy of tied-together leaves or grasses overhead for camouflage; 3–6 eggs are laid. The female incubates the egg. The eggs hatch after about 10 days. More than one brood may be raised. Females change their mates frequently and rarely stay within the same territory, while males are less mobile, maintaining non-overlapping song-territories which shift from day to day. Females can sometimes breed in their first year.

18-8-2024 CREU DE LONGA, ALBUFERA - SQUACCO HERON (Ardeola ralloides)

The squacco heron is a migrant, wintering in Africa. It is rare north of its breeding range. The species has been recorded in Fernando de Noronha islands, and more rarely in mainland South America, as a vagrant. This is a stocky species with a short neck, short thick bill and buff-brown back. In summer, adults have long neck feathers. Its appearance is transformed in flight, when it looks very white due to the colour of the wings.

The squacco heron's breeding habitat is marshy wetlands in warm countries. The birds nest in small colonies, often with other wading birds, usually on platforms of sticks in trees or shrubs. Three to four eggs are laid. They feed on fish, frogs and insects.

18-8-2024 CREU DE LONGA, ALBUFERA - BARN SWALLOW (Hirundo rustica)

The barn swallow (Hirundo rustica) is the most widespread species of swallow in the world, occurring on all continents, with vagrants reported even in Antarctica. It appears to have the largest natural distribution of any of the world's passerines, ranging over 251 million square kilometres globally.[not verified in body] It is a distinctive passerine bird with blue upperparts and a long, deeply forked tail. In Anglophone Europe, it is just called the swallow; in northern Europe, it is the only member of family Hirundinidae called a "swallow" rather than a "martin".

There are six subspecies of barn swallow, which breed across the Northern Hemisphere. Two subspecies, (H. r. savignii and H. r. transitiva) have fairly restricted ranges in the Nile valley and eastern Mediterranean, respectively. The other four are more widespread, with winter ranges covering much of the Southern Hemisphere.

The barn swallow is a bird of open country that normally nests in man-made structures and consequently has spread with human expansion. It builds a cup nest from mud pellets in barns or similar structures and feeds on insects caught in flight.


This species lives in close association with humans, and its insect-eating habits mean that it is tolerated by humans; this acceptance was reinforced in the past by superstitions regarding the bird and its nest. There are frequent cultural references to the barn swallow in literary and religious works due to both its living in close proximity to humans and its annual migration. The barn swallow is the national bird of Austria and Estonia.

18-8-2024 ULLAL DE BALDOVI, ALBUFERA - RED SWAMP CRAYFISH (Procambarus clarkii)

Procambarus clarkii, known variously as the red swamp crayfish, Louisiana crawfish or mudbug, is a species of cambarid crayfish native to freshwater bodies of northern Mexico, and southern and southeastern United States, but also introduced elsewhere (both in North America and other continents), where it is often an invasive pest.

P. clarkii is typically dark red, with long claws and head, small or no spines on the sides of its carapace just below the head, and rows of bright red bumps on the front and side of the first leg.

Male red swamp crayfish have bigger claws than females


The native range of P. clarkii is from northern Mexico and far southeastern New Mexico, through the Gulf States to the Florida Panhandle, as well as inland north through the Mississippi Basin to southern Illinois. It has also been introduced, sometimes deliberately, outside its natural range to countries in Asia, Africa, Europe and elsewhere in the Americas. In northern Europe, the populations are self-maintaining but not expanding, while in southern Europe, P. clarkii is multiplying and actively colonizing new territories at the expense of the native crayfish, Astacus astacus and Austropotamobius spp. Individuals are reported to be able to cross many miles of relatively dry ground, especially in wet seasons, although the aquarium trade and anglers may have hastened the spread in some areas (anglers using P. clarkii as fishing bait are thought to have introduced it to the state of Washington). Attempts have also been made to use P. clarkii as a biological control organism, to reduce levels of the snails involved in the lifecycle of schistosomiasis, leading to the dispersal of P. clarkii in, for instance, Kenya.

In Europe, P. clarkii is included since 2016 in the list of Invasive Alien Species of Union concern (the Union list). This implies that this species cannot be imported, bred, transported, commercialized, or intentionally released into the environment in the whole of the European Union.

The Grey heron (Ardea cinerea) is a large long-legged wading bird of the heron native to Europe and Asia and also parts of Africa. It lives in wetland areas and feeds on various aquatic creatures which it catches after standing stationary beside or in the water.

The plumage of the Grey heron is largely ashy-grey above, and greyish-white below with some black on the flanks. Adults have a head and neck white with a broad black supercilium that terminates in the slender, dangling crest, and bluish-black streaks on the front of the neck. The scapular feathers are elongated and the feathers at the base of the neck are also somewhat elongated. Immature birds lack the dark stripe on the head and are generally duller in appearance than adults, with a grey head and neck, and a small, dark grey crest. The pinkish-yellow beak is long, straight, and powerful, and is brighter in color in breeding adults. The iris is yellow and the legs are brown and very long.
