19-9-2023 MONTE CORONA, VALENCIA - EUROPEAN PAPER WASP (Polistes dominula)


The European paper wasp (Polistes dominula) is one of the most common and well-known species of social wasps in the genus Polistes. Its diet is more diverse than those of most Polistes species—many genera of insects versus mainly caterpillars in other Polistes—giving it superior survivability compared to other wasp species during a shortage of resources.

The dominant females are the principal egg layers, while the subordinate females ("auxiliaries") or workers primarily forage and do not lay eggs. This hierarchy is not permanent, though; when the queen is removed from the nest, the second-most dominant female takes over the role of the previous queen. Dominance in females is determined by the severity of the scatteredness in the coloration of the clypeus (face), whereas dominance in males is shown by the variation of spots of their abdomens. P. dominula is common and cosmopolitan due to their exceptional survival features such as productive colony cycle, short development time, and higher ability to endure predator attacks.

These wasps have a lek-based mating system. Unlike most social insects, 35% of P. dominula wasps in a colony are unrelated. It is considered an invasive species in Canada and the United States.

19-9-2023 MONTE CORONA, VALENCIA - STINK BUG (Sciocoris sideritidis)


Sciocoris sideritidis is a species of shield bug belonging to the family Pentatomidae, subfamily Pentatominae.

The head is quite characteristic and stretched with the ante-ocular part closer than in other species. Its eyes are prominent from the edge of the head. Scutellum is about as wide as long.

It is mainly found in France and Italy.

19-9-2023 MONTE CORONA, VALENCIA - SNAKE MILLIPEDE (Ommatoiulus rutilans)

Present in dry areas where the influence of the river does not reach. VULGAR NAME Cardador, millipede.

DESCRIPTION Up to 6 cm. Brownish-gray to dark brown in color, with short antennae; cylindrical body, with more than 40 rings; with 2 pairs of legs per segment except in the first ones; male with hooked front legs; solenomerite with a seminal groove and a cavity at the base. Ommatoiulus rutilans (C.L. Koch, 1847) 

When disturbed, the carder curls up forming a spiral in order to cover its soft, much more vulnerable parts, releasing a repellent wine-colored liquid. Sperm transfer can be direct or indirect, and the sperm, in most cases, is stored in the spermathecae or seminal receptacles possessed by the female, who will choose the moment of fertilization. Once fertilized, she will form eggs and bury them in galleries in the ground. After hatching, the neonates have three or six very short segments, going through numerous molts before reaching adulthood. Its detritivore and decomposer habits and its ability to create galleries and stir the soil, aerating it and promoting the oxidation of organic matter, make it appreciated by organic farmers where worms cannot live.



17-9-2023 TABERNES, VALENCIA - HOUSE SPARROW (FEMALE) (Passer domesticus)


 Noisy and gregarious, these cheerful exploiters of man's rubbish and wastefulness have managed to colonise most of the world. The ultimate avian opportunist perhaps. Monitoring suggests a severe decline in the UK house sparrow population, recently estimated as dropping by 71 per cent between 1977 and 2008 with substantial declines in both rural and urban populations. While the decline in England continues, Breeding Bird Survey data indicate recent population increases in Scotland, Wales and Northern Ireland.

18-9-2023 GANDIA MARJAL, VALENCIA - GREY HERON (Ardea cinerea)

Grey herons are apex predators in their aquatic ecosystem. Fish, amphibians, crustaceans, and insects are caught in shallow water with the heron's long bill. It has also been observed catching and killing juvenile birds such as ducklings, and occasionally takes birds up to the size of a water rail or white-throated rail.s, rats, stoats and young rabbits are additionally caught.

Prey items vary in size from 1 cm-long fish and invertebrates, weighing less than 1g, to 30 cm-long carps and 57cm eels. While chicks tend to have smaller prey, individual prey caught by fully-grown Grey Herons commonly exceed 100g in weight and occasionally exceed 500g. One paper reports that an adult heron managed to catch and swallow sea trout weighing 680g. It may stand motionless in the shallows, or on a rock or sandbank beside the water, waiting for prey to come within striking distance. Alternatively, it moves slowly and stealthily through the water with its body less upright than when at rest and its neck curved in an "S". It is then able to straighten its neck and strike with its bill very quickly. Small fish are swallowed head first, and larger prey and eels are carried to the shore where they are subdued by being beaten on the ground or stabbed by the bill. They are then swallowed or have hunks of flesh torn off. For prey such as small mammals and birds or ducklings, the prey is held by the neck and either drowned, suffocated, has its neck snapped with the heron's beak, or is bludgeoned against the ground or a nearby rock, before being swallowed whole. The bird regurgitates pellets of indigestible material such as fur, bones, and the chitinous remains of insects. The main hunting periods are around dawn and dusk, but it is also active at other times of the day. At night it roosts in trees or on cliffs, where it tends to be gregarious.


 

18-9-2023 XERACO, VALENCIA - BROAD SCARLET DRAGONFLY (MALE) (Crocothemis erythraea)

The scarlet dragonfly (Crocothemis erythraea) is a species of dragonfly in the family Libellulidae. Its common names include broad scarlet, common scarlet-darter, and scarlet darter.

The scarlet dragonfly is a common species in southern Europe and throughout Africa. It also occurs across western Asia as far as southern China.[1] It is a very rare vagrant in Britain. Its first record in the country was at Hayle Kimbro Pool, The Lizard, Cornwall, on 7 August 1995. Since then there have been a few further records at scattered locations throughout Britain.


 

18-9-2023 XERACO, VALENCIA - CATALONIA WALL LIZARD (Podarcis liolepis)


Podarcis liolepis, the Columbretes wall lizard or Catalan wall lizard, is very similar to the other lizards in the genus Podarcis. This species was formerly described as a subspecies of the Iberian wall lizard, but has now been elevated to species status.

18-9-2023 XERACO, VALENCIA - LAMENTING GRASSHOPPER (Eyprepocnemis plorans)


Eyprepocnemis plorans, the lamenting grasshopper, is a species of insect in the family Acrididae. It is the type species of the genus Eyprepocnemis, and is found in Africa, parts of the Middle East, and southern Europe. It typically inhabits wetlands and other moist habitats.

This is a medium-sized grasshopper, with females growing to a length of about 4.5 cm (1.8 in), while males are slightly smaller. The general colour is greyish-brown. The head and prothorax have a central dark band edged with paler stripes. The eye has a longitudinal dark streak, a characteristic shared by Anacridium aegyptium, Heteracris annulosa and Heteracris adspersa. The femurs of the hind legs have greenish, blue and yellow striations, and the hind tibia have reddish or bluish iridescence, and black and white spines.


Eyprepocnemis plorans is native to much of Africa, parts of the Middle East such as Iran, and southern Europe, where it is present in southern Greece, southern Italy, Sicily, Sardinia and southern Spain. It seems to be expanding its range northwards in Italy, possibly as a result of putative climate change. It usually occurs in wetlands, reed beds, freshwater and salt marshes, riverside vegetation, coastal vegetation and man-made habitats. It appreciates vertical-growing stems such as reeds, and habitats with tall forbs mixed with lower-growing plants.

18-9-2023 XERACO, VALENCIA - MEDITERRANEAN SKIPPER BUTTERFLY (Gegenes nostrodamus)

17-9-2023 MONTE CORONA, VALENCIA - OLD WORLD WEBWORM MOTH (Hellula undalis)

Hellula undalis, the cabbage webworm or Old World webworm, is a moth of the family Crambidae. It is a widespread species which is found from Europe across Asia to the Pacific. It was first described from Italy.

The wingspan is about 18 mm. Adult moths have fawn forewings, each with sinuous pale lines and a kidney-shaped mark. The hindwings are a uniform grey darkening at the margins.

The larvae feed on a wide range of plants, mainly of the family Brassicaceae. Recorded food plants include broccoli, crucifers, head cabbage, Chinese cabbage, spoon cabbage, daikon radish, horseradish, mustard, radish and turnip. It is considered a serious agricultural pest. The larvae initially bore into the stem of growing shoots, later instars mine the leaves and leaf stems. It makes a web of silk around the feeding area which accumulates frass. The caterpillar is 12–15 mm long and is whitish with pinkish-brown longitudinal stripes.

Pupation occurs within this silken shelter. The pupa is formed in a loose cocoon of webbed-together particles of soil or other matter and is about 8 mm long, shining pale brown with a dark stripe on the back.

16-9-2023 MONTE CORONA, VALENCIA - BARBARIAN GRASSHOPPER (Calliptamus barbarus)

Calliptamus barbarus is a species of short-horned grasshopper in the family Acrididae. It is found in the Palearctic.

Calliptamus barbarus or Costa's rose wing is a right-winged insect from the family locust (Acrididae). The scientific name of this species was first validly published in 1836 by Oronzio Gabriele Costa.

The Barbarian grasshopper is not toxic and does not usually pose a threat to human health. There is no need to be overly concerned.

The Barbarian grasshopper feeds on plants and usually does not cause a major problem. However, If you observe the number getting larger, you need to take it seriously.


 

16-9-2023 MONTE CORONA, VALENCIA - BLUE ROCK THRUSH (FEMALE) (Monticola solitarius)


The blue rock thrush is a starling-sized bird, 21–23 cm (8.3–9.1 in) in length with a long slim bill. The breeding male of the nominate subspecies is unmistakable, with all blue-grey plumage apart from its darker wings. Females and immatures are much less striking, with dark brown upperparts, and paler brown scaly underparts. The male of the subspecies M. s. philippensis has rufous-chestnut plumage from the mid-breast down to the undertail. Both sexes lack the reddish outer tail feathers of rock thrush.

The male blue rock thrush sings a clear, melodious call that is similar to, but louder than the call of the rock thrush.

15-9-2023 MONTE CORONA, VALENCIA - SPINY TOAD (JUVENILE) (Bufo spinosus)

Bufo spinosus is a large and robust toad with a snout-vent length of 58.6 - 112 mm in males and 65 - 180 mm in females. Its head is relatively broad, and the region between the eyes is either flat or slightly concave. The snout is short and rounded. The tympanum is subtly visible and rounded, and its diameter does not exceed half the eye. The parotoid glands are large, elongated, and divergent at the posterior end. The eyes are prominent with a horizontally oval pupil. The skin is warty on the back and granular on the underside. Its warts usually end in a keratinized tip, resulting in a spiny appearance, though not all individuals express this. These keratinized warts are especially prominent between the corner of the mouth and the parotoid. The fingers, of which the third is the longest, are short. No information is available on the relative finger lengths. There are two palmar tubercles on the hands. The hind limbs are webbed, and have a pair of metatarsal tubercles, with the internal metatarsal tubercle being larger than the external metatarsal tubercle. No information is available on the relative toe lengths. There is a pair of subarticular tubercles on the hands and the feet that may be fused in older adults.


 

15-9-2023 MONTE CORONA, VALENCIA - WAVE MOTH (Scopula submutata)


 Scopula submutata, the Mediterranean lace border, is a moth of the family Geometridae. It is found in southern Europe, North Africa and the Near East. The habitat consists of open, dry grassland and rocky slopes.

The wingspan is 20–25 millimetres (0.79–0.98 in). There are two generations per year, with adults on wing from May to October.

The larvae feed on Thymus species and Origanum vulgare.

15-9-2023 MONTE CORONA, VALENCIA - HALF EDGED WALL JUMPING SPIDER (Menemerus semilimbatus)


 enemerus 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.

Menemerus semilimbatus is a Mediterranean species widely distributed in Europe, southern Asia and in Africa. In the Americas, it has been reported for Argentina, Chile, Ecuador and USA.

These spiders are synanthropic living in gardens and inside and on the outside of houses. It is usually found on the walls of buildings where it stalks its prey.



14-9-2023 MONTE CORONA, VALENCIA - EUROPEAN MANTIS (FEMALE) (Mantis religiosa)

The European mantis (Mantis religiosa) is a large hemimetabolic insect in the family of the Mantidae ('mantids'), which is the largest family of the order Mantodea (mantises). Their common name praying mantis is derived from the distinctive posture of the first pair of legs that can be observed in animals in repose. It resembles a praying attitude. Both males and females have elongated bodies with two pairs of wings. The most striking features that all Mantodea share are a very mobile, triangular head with large compound eyes and their first pair of legs (the 'raptorial legs'), which is highly modified for the efficient capture and restraint of fast-moving or flying prey.


 The great variation in the coloration of M. religiosa from different shades of yellow, brown, green, and sometimes black has been the cause of numerous hypotheses and studies for over 100 years. However, no generally accepted answer about reason, benefit, or mechanism of the coloration or the change of coloration has been found.

Di Cesnola observed in 1904 that green mantids were found on fresh green grass, whereas brown individuals seemed to prefer brown grass burned by the sun. When forced to change the location as to no longer match their coloration, almost all the ‘not matching’ animals were killed by predators such as birds. This indicates a camouflaging purpose of the coloration.
Przibram also observed in 1907 that a change in temperature can trigger a change in coloration: animals that hatched in a cold environment turned green after moulting when heat and sunlight were provided. Without the change in temperature and only a change in the color of the background, no change in coloration occurred. This finding contradicts with Di Cesnola, who claims to have observed the animals within the same time and location (and therefore the same temperature).

12-7-2023 MONTE CORONA, VALENCIA - BAGWORM MOTH (Placodoma ragonoti)


The Psychidae (bagworm moths, also simply bagworms or bagmoths) are a family of the Lepidoptera (butterflies and moths). The bagworm family is fairly small, with about 1,350 species described. Bagworm species are found globally, with some, such as the snailcase bagworm (Apterona helicoidella), in modern times settling continents where they are not native.

Another common name for the Psychidae is "case moths", but this is just as well used for the case-bearers (Coleophoridae). The names refer to the habits of caterpillars of these two families, which build small protective cases in which they can hide. The bagworms belong to the superfamily Tineoidea, which is a basal lineage of the Ditrysia (as is Gelechioidea, which includes case-bearers). This means that the bagworms and case-bearers are only as closely related to each other as either is to butterflies (Rhopalocera).

Most bagworms are inoffensive to humans and inconspicuous; some are occasional nuisance pests. However, a few species can become more serious pests, and have caused significant damage e.g. to wattle (Acacia mearnsii) in South Africa and orange (Citrus × sinensis) in Florida. If detected early, picking the cases from the trees while in their pupa stage is an effective way to check an infestation; otherwise, insecticides are used. One bagworm species, the fangalabola (Deborrea malgassa) of Madagascar, is in some places encouraged to breed on wattle trees, because its pupae are collected as a protein-rich food.

12-9-2023 BOLOGNA, ITALY - RIVER COOTER TURTLE (Pseudemys concinna)


The river cooter (Pseudemys concinna) is a species of freshwater turtle in the family Emydidae. The species is native to the central and eastern United States, but has been introduced into parts of California, Washington, and British Columbia.

The river cooter basks on logs or sun-warmed rocks, and is frequently found in the company of other aquatic basking turtles (sliders and painteds) sometimes piled up on top of each other. All are quick to slip into the water if disturbed. Diurnal by nature, P. concinna wakes with the warming sun to bask and forage. It can move with surprising speed in the water and on land. It is not unusual for it to wander from one body of fresh water to another, but many individuals seem to develop fairly large home ranges, which they seldom or never leave. It sleeps in the water, hidden under vegetation. In areas that are quite warm it remains active all winter, but in cooler climates can become dormant during the winter for up to two months, in the mud, underwater. It doesn't breathe during this time of low metabolism, but can utilize oxygen from the water, which it takes in through the cloaca. The river cooter prefers to be well hidden under aquatic plants during the winter dormancy period or while sleeping each night.

12-9-2023 BOLOGNA, ITALY - FALSE MAP TURTLE (Graptemys pseudogeographica)


The false map turtle (Graptemys pseudogeographica) is a species of turtle endemic to the United States. It is a common pet species. Two subspecies are recognized, including the nominotypical subspecies described here.

The false map turtle is a strong swimmer and prefers rivers and large creeks with moderate currents, containing aquatic vegetation, as well as snags or floating logs. They are also comfortable in deep and swift water. The turtles are present in oxbow lakes and sloughs, but are absent from lakes, ponds, or small streams. Basking is important to these turtles, and they may even be found on steep, slippery snags.

12-9-2023 BOLOGNA, ITALY - POND SLIDER TERRAPIN (Trachemys scripta),

The pond slider (Trachemys scripta) is a species of common, medium-sized, semiaquatic turtle. Three subspecies are described, the most recognizable of which is the red-eared slider (T. s. elegans), which is popular in the pet trade and has been introduced to other parts of the world by people releasing it to the wild. Hatchling and juvenile pond sliders have a green upper shell (carapace), yellow bottom shell (plastron), and green and yellow stripes and markings on their skin. These patterns and colors in the skin and shell fade with age until the carapace is a muted olive green to brown and the plastron is a dull yellow or darker. Some sliders become almost black with few visible markings. The carapace is oval with a bit of rounding and a central crest with knobs, but these features soften and fade with age, adults being smoother and flatter. For determining an adult slider's sex, males typically have much longer front claws than adult females, while females usually have shorter, more slender tails than males. Their lifespans range from 20 to 50 years.

12-9-2023 BOLOGNA, ITALY - WHITE LEGGED DAMSELFLY (Platycnemis pennipes)


The white-legged damselfly or blue featherleg (Platycnemis pennipes) is a damselfly of slow-flowing, muddy waters. It occurs from the Atlantic to Siberia and is often abundant throughout its range.

This species favours unshaded slow-flowing sections of muddy rivers with abundant floating vegetation. it has been recorded in tidal rivers and the larvae seem well able to tolerate brackish water. It also occurs in muddy streams but is rare in lakes or ponds of any sort.

 In north-west Europe, it is mostly confined to flowing waters.

Mating is preceded by the male displaying his white legs in a fluttering display flight in front of females. Elongated eggs are laid whilst in tandem, into emergent stems and especially the underside of floating leaves. The larvae live amongst bottom debris and emerge after two years.


After emerging, adults tend to congregate in the shelter of tall vegetation, although some immatures wander away from water and have been found five kilometres away from the nearest breeding site. 

12-9-2023 BOLOGNA, ITALY - EUROPEAN 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 natural range spans much of the mainland Europe except from the north and very south and extends to Turkey. It occurs as introduced populations in southern Britain where one such population in the seaside town of Ventnor on the Isle of Wight has become somewhat famous, and also in North America. There has been some scientific debate as to whether the populations in Southern England represent the northern edge of their native range.

9-9-2023 MONTE CORONA, VALENCIA - MEDITERRANEAN KATYDID (Phaneroptera nana)

Phaneroptera nana, common name southern sickle bush-cricket, is a species in the family Tettigoniidae and subfamily Phaneropterinae. It has become an invasive species in California where it may be called the Mediterranean katydid.

This bush cricket is native to mainland Europe, the Near East and North Africa. The Indo-Malayan species Phaneropera subcarinata, described by Bolívar, is morphologically similar to P. nana, and was classified under the P. nana name by Carl Brunner von Wattenwyl. As an invasive species, it has spread to the San Francisco Bay Area and may be widespread in the Los Angeles Basin, with records of its presence in California dating from at least 1952. In addition, it has been recorded in South America and hypothesized in the Annals of Carnegie Museum to have spread via shipping.

It mainly inhabits sunny and dry habitats, especially shrubs and low branches of trees.
