12-10-2020 BENIOPA, VALENCIA - WALL BROWN BUTTERFLY (Lasiommata megera)
The Wall Brown (Lasiommata megera) is a medium-sized butterfly (wingspan 36–50mm) with distinctive orange-brown wings, dark brown, zebra-like markings, and white-pupilled spots. Famous for basking on sunny, bare, stony areas (walls, paths, coastal cliffs), they have experienced a severe population decline in the UK and are now mostly found along the coast.
Key Facts About the Wall Brown
Appearance: Males are smaller and darker with a prominent, dark brown scent stripe (sex brand) on their forewings. Females are larger, with brighter orange coloring.
Behavior: They are rapid fliers, often seen fluttering close to the ground, but frequently bask on rocks, sunny walls, and dirt paths.
The imago flies from April to October in two or three generations depending on locality and altitude. The larva feeds on grasses in the genera Festuca, Bromus, Deschampsia, Poa, Dactylis and Brachypodium.
"The egg is pale green when first laid, and in shape it is almost spherical, but rather higher than broad; it is finely ribbed and reticulated, but unless examined through a lens it appears to be quite smooth. The caterpillar when full grown is whitish-green, dotted with white. From the larger of these dots on the back arise greyish bristles; the three lines on the back (dorsal and sub-dorsal) are whitish, edged with dark green; the line on the sides (spiracular) is white, fringed with greyish hairs; anal points green, hairy, extreme tips white. Head larger than the first ring (first thoracic segment), green dotted with white and hairy, jaws marked with brownish. The chrysalis is green, with yellow-tinted white markings on the edge of the wing covers and ridges; the spots on the body are yellowish, or sometimes white. Occasionally the chrysalids are blackish, with white or yellow points on the body". (South 1906)
Life Cycle & Habitat: They are found in hot, open, rocky environments, including coastal paths, quarries, and disused railway lines. They overwinter as caterpillars (larvae).
Broods: There are usually two to three generations per year, appearing from April through October.
Diet: Caterpillars feed on various grasses, including tor-grass, bent, and fescue species.
Conservation Status: This species has seen a massive, rapid decline (>80% since 1976), particularly inland.
They are sometimes confused with the Gatekeeper or Speckled Wood but are distinguished by their intense orange color and preference for rocky, open, barren habitats.

9-10-2020 MONTE CORONA, VALENCIA - NOMAD DRAGONFLY (FEMALE) (Sympetrum fonscolombii)
%20(Sympetrum%20fonscolombii)%2020.jpg)
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.
11-10-2020 GANDIA, VALENCIA - EURASIAN HOOPOE (Upupa epops)
The Eurasian hoopoe or common 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".
The Eurasian hoopoe is native to Europe, Asia and Africa. It is migratory in the northern part of its range. Some ornithologists consider the Madagascar hoopoes as a subspecies. The African hoopoe, subspecies U. e. africana, has sometimes been treated as a separate species.
The Eurasian hoopoe was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae. He cited the earlier descriptions by the French naturalist Pierre Belon and by the Swiss naturalist Conrad Gessner, both of which had been published in 1555. Linnaeus placed the Eurasian hoopoe with the northern bald ibis and the red-billed chough in the genus Upupa and coined the binomial name Upupa epops. The specific epithet epops in the Ancient Greek word for a hoopoe.
The muscles of the head allow the hoopoe's bill to be opened when it is inserted into the ground
The Eurasian hoopoe is a medium-sized bird, 25–32 cm (9.8–12.6 in) long, with a 44–48 cm (17–19 in) wingspan. It weighs 46–89 g (1.6–3.1 oz).[8] The species is highly distinctive, with a long, thin tapering bill that is black with a fawn base. The strengthened musculature of the head allows the bill to be opened when probing inside the soil. The hoopoe has broad and rounded wings capable of strong flight; these are larger in the northern migratory subspecies. The hoopoe has a characteristic undulating flight, which is like that of a giant butterfly, caused by the wings half closing at the end of each beat or short sequence of beats. Adults may begin their moult after the breeding season and continue after they have migrated for the winter.
The call is typically a trisyllabic oop-oop-oop, which may give rise to its English and scientific names, although two and four syllables are also common. An alternative explanation of the English and scientific names is that they are derived from the French name for the bird, huppée, which means crested. In the Himalayas, the calls can be confused with that of the Himalayan cuckoo (Cuculus saturatus), although the cuckoo typically produces four notes. Other calls include rasping croaks, when alarmed, and hisses. Females produce a wheezy note during courtship feeding by the male.
The Eurasian hoopoe is widespread in Europe, Asia, and North Africa and northern Sub-Saharan Africa. Most European and north Asian birds migrate to the tropics in winter. Those breeding in Europe usually migrate to the Sahel belt of sub-Saharan Africa. The birds predominantly migrate at night. In contrast, the African populations are sedentary all year. The species has been a vagrant in Alaska; U. e. saturata was recorded there in 1975 in the Yukon Delta. Hoopoes have been known to breed north of their European range, and in southern England during warm, dry summers that provide plenty of grasshoppers and similar insects, although as of the early 1980s northern European populations were reported to be in the decline, possibly due to changes in climate. In 2015, a record numbers of hoopoes were recorded in Ireland, with at least 50 birds recorded in the southwest of the country. This was the highest recorded number since 1965 when 65 individuals were sighted.
The hoopoe has two basic requirements of its habitat: bare or lightly vegetated ground on which to forage and vertical surfaces with cavities (such as trees, cliffs or even walls, nestboxes, haystacks, and abandoned burrows) in which to nest. These requirements can be provided in a wide range of ecosystems, and as a consequence the hoopoe inhabits a wide range of habitats such as heathland, wooded steppes, savannas and grasslands, as well as forest glades.
Hoopoes make seasonal movements in response to rain in some regions such as in Ceylon and in the Western Ghats. Birds have been seen at high altitudes during migration across the Himalayas. One was recorded at about 6,400 m (21,000 ft) by the first Mount Everest expedition.
In what was long thought to be a defensive posture, hoopoes sunbathe by spreading out their wings and tail low against the ground and tilting their head up; they often fold their wings and preen halfway through. They also enjoy taking dust and sand baths.

10-10-2020 MONTE CORONA, VALENCIA - EGYPTIAN BIRD GRASSHOPPER (Anacridium aegyptium)
Anacridium aegyptium, the Egyptian grasshopper or Egyptian locust, is a species of insect belonging to the subfamily Cyrtacanthacridinae.
A fairly common species, the Egyptian grasshopper is present in most of Europe, the Afrotropical realm, eastern Palearctic realm, the Near East, and North Africa, and has recently been observed in Cape Town, South Africa.
These grasshoppers inhabit trees and shrubs, scrub land, maquis, and orchards in warm and bright environments, at an elevation from sea level to 1,500 m.
Anacridium aegyptium is one of the largest European grasshoppers. Adult males grow up to 30–56 mm (1.2–2.2 in) long, while females reach 46–70 mm (1.8–2.8 in) in length. Their bodies are usually gray, brown, or olive-coloured, and their antennae are relatively short and robust. The tibiae of the hind legs are blue, while the femora are orange. The hind femora have characteristic dark marks. They are also easily identified by their characteristic eyes, which have vertical black and white stripes. Their pronota show a dorsal orange stripe and several small white spots. The wings are clear with dark marks.

8-10-2020 MONTE CORONA, VALENCIA - MEDITERRANEAN RECLUSE SPIDER (Loxosceles rufescens)
The Mediterranean recluse spider (Loxosceles rufescens) is a species of spider that originated in the Mediterranean region as its name implies, but can now be found in many parts of the world and is listed as one of the most invasive spiders worldwide. Usually dwelling in caves, this species will also inhabit basements and tunnels. The spider hunts at night and eats insects including silverfish and cockroaches, and they usually target smaller species.
Similar to other species in their genus, bites from L. rufescens can cause necrosis and, for some individuals, systemic damage due to the enzyme sphingomyelinase D. Pest control may be undertaken with similar strategies as used for the brown recluse spider.
Loxosceles rufescens is a cave-dwelling arachnid that is nearly indistinguishable in appearance from Loxosceles reclusa, the brown recluse spider. Individuals can be identified as medium-sized spiders distinguished by three pairs of two eyes organized in the shape of a triangle (spiders commonly have eight eyes), with a violin-shaped pattern on their cephalothorax. This spider belongs to the genus Loxosceles which contains many of the most dangerous spiders in the world. Both males and females grow to approximately 7–7.5 mm in length.
Loxosceles rufescens egg sacs contain approximately 40 eggs that each take a few weeks to hatch, depending on the temperature. The young spiders grow slowly and produce molts during their growing phase. These molts often have a pale ghostly appearance. Mediterranean recluse spiders typically live from one to three years. The webs of Mediterranean recluse spiders spin function as a daytime hiding spot and provide seclusion for the egg sacs. The webs are very thin and fragile, formed by strands of silk laid in a disorganized manner.
The Mediterranean recluse is listed as one of the most invasive species in the world. It is native to the Mediterranean area and western Asia, including parts of Europe and Northern Africa, and prefers warm temperatures and generally dry weather. Today, this spider has a global distribution due to increased human travel and the increase of transported goods.
This species has been introduced to Madagascar, southeast Asia from India to Japan, Australia, and numerous Atlantic and Pacific islands (including four in the Hawaiian archipelago) and in North America, it has been recorded in over 20 of the United States, widely scattered from California to Florida and north to Michigan, as well as Ontario, Canada.
In South Africa, only a single specimen was recorded from Cape Town in 1914.
8-10-2020 MONTE CORONA, VALENCIA - PINK BARRED EUBLEMMA MOTH (Eublemma cochylioides)
Eublemma cochylioides, the pink-barred eublemma, is a species of moth of the family Erebidae described by Achille Guenée in 1852.
It is found throughout the Old World countries (including France). Besides France, it can also be found in such European countries as Greece and Portugal, and on islands such as Crete and Cyprus. It is also common in Asian ones such as Hong Kong, India, Sri Lanka, Japan, and Taiwan, where it might migrate. When comes African migration the species resort to South Africa, from which it might migrate to such Australian islands as Fiji and Tonga, and including Queensland, New South Wales, and Western Australia.
The wingspan is about 20 millimetres (0.79 in). Male with no pit in the membrane of forewing towards apex, which is somewhat acute. Head and thorax ochreous white. Forewings with ochreous-white basal area, bounded by a very oblique fulvous line, beyond which the area is bright pink. Outer margin fulvous suffused. Two white spots can be seen near outer angle, with some black scaled on their outer edge. Hindwings pale, suffused with fuscous towards outer margin.
The larvae have been recorded on Elephantopus species and Prenanthes spinosa.
