6-10-2020 MONTE CORONA, VALENCIA - CARPET MOTH (Subfamily Larentiinae)
Larentiinae is a subfamily of moths containing roughly 5,800 species that occur mostly in the temperate regions of the world. They are generally considered a subfamily of the geometer moth family (Geometridae) and are divided into a few large or good-sized tribes, and numerous very small or even monotypic ones which might not always be valid. Well-known members are the "pug moths" of the Eupitheciini and the "carpets", mainly of the Cidariini and Xanthorhoini. The subfamily was described by Philogène Auguste Joseph Duponchel in 1845.
But the Larentiinae characteristically tend to have much longer foreleg tarsi and hindleg tibiae than their relatives, and also have hairy or toothed extensions on the upperside sections of the transtilla; their caterpillars often have the abdominal prolegs reduced already (as is typical for the more advanced geometer moths), and the Larentiinae's tympanal organs have a unique and characteristic structure.
Carpet moths in the subfamily Larentiinae (family Geometridae) are small-to-medium-sized moths known for intricate, wavy, carpet-like patterns on their wings. While named for their appearance, most Larentiinae larvae feed on plants, not household fabrics, distinguishing them from destructive Tineidae "carpet moths". They are widely distributed, particularly in temperate regions.
Key Facts about Larentiinae "Carpet" Moths.
Appearance: They are generally small, with wingspans often around \(20\text{mm}\), featuring complex brown, green, or grey transverse, wavy lines.
Behavior: Adults are often attracted to light.Diet & Habitat: While many species are named for their wing patterns, their caterpillars typically feed on specific host plants (e.g., knotweeds) rather than household materials.
Diversity: This is a large subfamily within the Geometridae family, comprising roughly 5,800 species, including specialized groups like "pug moths".
Confusion with Pests: They are often confused with the Tapestry Moth (Trichophaga tapetzella), which is a separate species in the Tineidae family that actually feeds on wool, fur, and carpets.
6-10-2020 MONTE CORONA, VALENCIA - PUG MOTH (Genus Eupithecia)
Eupithecia is the largest genus of moths of the family Geometridae, and the namesake and type genus of tribe Eupitheciini. Species in the genus are, like those of other genera in the tribe, commonly known as pugs. The genus is highly speciose, with over 1400 species, and members of the genus are present in most of the world with exception of Australasia. Roughly a quarter of described Eupithecia species occur in the Neotropical realm, where they have an especially high species diversity in the montane rain forests of the Andes. The genus includes a few agricultural pest species, such as the currant pug moth, Eupithecia assimilata, which is a pest on hops, and the cloaked pug moth, Eupithecia abietaria, which is a cone pest in spruce seed orchards.
Adult specimens of Eupithecia are typically small, often between 12 and 35 mm, with muted colours, and display a large amount of uniformity between species. As a result, identification of a specimen as part of genus Eupithecia is generally easy, but identifying the exact species is difficult and often reliant on examination of the dissected genitals. Most species share a characteristic resting pose in which the forewings are held flat at a right angle to the body—that is, the costal margins of both forewings form a more-or-less horizontal line—while the hindwings are largely covered by the forewings. They are generally nocturnal.

5-10-2020 GATA DE GORGOS, ALICANTE - SHORT HORNED GRASSHOPPER (Genus Calliptamus)
Calliptamus is a genus of medium-sized, short-horned grasshoppers belonging to the family Acrididae and subfamily Calliptaminae. Known for their stout bodies and often red or pink hind wings, these insects are primarily distributed across the Mediterranean Basin, Europe, Africa, and Asia, reaching as far as Japan.
Here are the key facts about the genus Calliptamus:
Species and Classification
Number of Species: The genus includes approximately 17 recognized species.
Key Species: The most well-known species are Calliptamus italicus (Italian Locust), Calliptamus barbarus (Barbary Grasshopper), Calliptamus plebeius (Canarian pincer grasshopper), and Calliptamus wattenwylianus.
Identification Challenges: Identification is difficult because morphological characteristics vary greatly depending on habitat (plain, desert, mountain) and region. Identification often requires examining the male genitalia (aedeagus).

23-5-2019 MANA POOLS, ZIMBABWE - BLACK KITE (Milvus migrans)
%2010.jpg)
The black kite (Milvus migrans) is a medium-sized bird of prey in the family Accipitridae, which also includes many other diurnal raptors. It is thought to be the world's most abundant species of Accipitridae, although some populations have experienced dramatic declines or fluctuations. Current global population estimates run up to 6 million individuals.
Unlike others of the group, black kites are opportunistic hunters and are more likely to scavenge. They spend much time soaring and gliding in thermals in search of food. Their angled wing and distinctive forked tail make them easy to identify. They are also vociferous with a shrill whinnying call.
The black kite is widely distributed through the temperate and tropical parts of Eurasia and parts of Australasia and Oceania, with the temperate region populations tending to be migratory. Several subspecies are recognized and formerly had their own English names. The European populations are small, but the South Asian population is very large.
Black kites can be distinguished from red kites by the slightly smaller size, less forked tail (visible in flight), and generally dark plumage without any rufous. The sexes are alike though the male is a little smaller and less aggressive (this is the case in most birds of prey). They weigh on average 735 grams. The upper plumage is brown but the head and neck tend to be paler. The patch behind the eye appears darker. The outer flight feathers are black and the feathers have dark cross bars and are mottled at the base. The lower parts of the body are pale brown, becoming lighter towards the chin. The body feathers have dark shafts giving it a streaked appearance. The cere and gape are yellow, but the bill is black (unlike that of the yellow-billed kite). The legs are yellow and the claws are black. They have a distinctive shrill whistle followed by a rapid whinnying call. Males and females have the same plumage but females are longer than males and have a little larger wingspan. Their wingspan is around 150 cm.
The species is found in Europe, Asia, Africa and Australia. The temperate populations of this kite tend to be migratory while the tropical ones are resident. European and central Asian birds (subspecies M. m. migrans and black-eared kite M. m. lineatus, respectively) are migratory, moving to the tropics in winter, but races in warmer regions such as the Indian M. m. govinda (small Indian/pariah kite), or the Australasian M. m. affinis (fork-tailed kite), are resident. In some areas such as in the United Kingdom, the black kite occurs only as a wanderer on migration. These birds are usually of the nominate race, but in November 2006 a juvenile of the eastern lineatus, not previously recorded in western Europe, was found in Lincolnshire.
Black kites are most often seen gliding and soaring on thermals as they search for food. Their flight is buoyant and the bird glides effortlessly, changing directions easily. They will swoop down with their legs lowered to snatch small live prey, fish, household refuse and carrion, for which behaviour they are known in British military slang as the shite-hawk. They are opportunist hunters and have been known to take birds, bats, and rodents. They are attracted to smoke and fires, where they seek escaping prey. Kites are also known to spread fires by picking and dropping burning twigs so as to flush prey, leading to them being known in some circles as "firehawks". The Indian populations are well adapted to living in cities and are found in densely populated areas.
4-10-2020 MONTAVERNER, VALENCIA - EUROPEAN STONECHAT (Saxicola rubicola)
The European stonechat, Saxicola rubicola, is a small, charming passerine bird, once thought to be a member of the thrush family but now placed within the Old World flycatcher family, Muscicapidae. This species exhibits a striking sexual dimorphism, with males donning a black plumage with vibrant orange throats and females wearing a more subdued brown.
Males in their summer plumage are unmistakable with their black heads, orange throats, and white bellies. They also sport a distinctive white half-collar and small white patches on the wings and rump. Females, on the other hand, are predominantly brown with less pronounced white wing patches. Both sexes have notably short wings, which are shorter than those of their migratory relatives.
The European stonechat favors heathlands, coastal dunes, and open grasslands dotted with shrubs, brambles, and heather. These habitats provide the perfect backdrop for their active foraging and breeding behaviors.
4-10-2020 MONTAVERNER, VALENCIA - EUROPEAN RABBIT (Oryctolagus cuniculus)
%2020.jpg)
The European rabbit is smaller than the European hare and Mountain hare and lacks black ear tips, as well as having proportionately shorter legs. The fur of the European rabbit is generally greyish-brown, but this is subject to much variation. The guard hairs are banded brown and black, or grey, while the nape of the neck and scrotum are reddish. The chest patch is brown, while the rest of the underparts are white or grey. A white star shape is often present on kits' foreheads but rarely occurs in adults. The whiskers are long and black, and the feet are fully furred and buff-coloured. The tail has a white underside, which becomes prominent when escaping danger. This may act as a signal for other rabbits to run. Moulting occurs once a year, beginning in March on the face and spreading over the back. The underfur is completely replaced by October-November. The European rabbit exhibits great variation in colour, from light sandy to dark grey and completely black. Such variation depends largely on the amount of guard hairs relative to regular pelage.
%2021.jpg)
European rabbits are found in southwestern Europe (including Portugal, Spain, and western France) and in northwest Africa (including Morocco and Algeria). Their ideal habitat consists of short grasslands with secure refuge (such as burrows, boulders, hedgerows, scrub, and woodland) near feeding areas. In large coniferous plantations, European rabbits only occur in peripheral areas and along fire breaks and rides.
European rabbits are herbivores (graminivores) and coprophages. They eat a wide variety of herbage, especially grasses, favoring the young, succulent leaves and shoots of the most nutritious species. Hungry rabbits in winter may eat tree bark and blackberries. Like other leporids, European rabbits also consume their own fecal pellets, which are filled with protein-rich bacteria.
4-10-2020 MONTAVERNER, VALENCIA - RED LEGGED PARTRIDGE (Alectoris rufa)
%2020.jpg)
The red-legged partridge, Alectoris rufa, is a plump gamebird belonging to the pheasant family, Phasianidae. It is colloquially known as the French partridge, setting it apart from the English or grey partridge. Exhibiting a light brown back, grey breast, and buff belly, this bird is easily recognized by its white face with a striking black gorget. The flanks are adorned with rufous streaks, and it stands on characteristically red legs. When startled, it may choose to run, but it can also take to the air with rounded wings for short distances.
Adults display a sandy-brown upper body, a pinkish-buff belly, and a pale grey breast. A black gorget with bold rufous and black flank bars, a cream throat, pink legs, and a red bill and eye ring are distinctive features. The eye is encircled by a bright red ring, adding to its striking appearance.
The red-legged partridge favors dry lowlands for breeding, such as farmland and open stony areas. It nests on the ground and can be found cohabiting with wild rabbits.
%2021.jpg)
Originally from southwestern Europe, including France, Iberia, and northwest Italy, the red-legged partridge has been introduced and naturalized in parts of England and Wales. It forms flocks outside the breeding season and is a non-migratory terrestrial species.
This bird is known for its preference to run rather than fly when disturbed. However, it is capable of short flights if necessary. It is a sociable species, forming flocks when not breeding.
The red-legged partridge vocalizes with a distinctive three-syllable call, which can be phonetically described as "ka-chu-chu."
%2022.jpg)
The species is known to breed in dry lowland areas, laying eggs in a ground nest. It has the remarkable ability to breed two clutches simultaneously.
The rock partridge (Alectoris graeca) is very similar in appearance and occupies southeastern Europe, replacing the red-legged partridge there.
Primarily seed-eating, the red-legged partridge's diet also includes insects, which are particularly important for the protein needs of the young.
The red-legged partridge is currently classified as Near Threatened by the IUCN, with concerns about its decline across its range due to habitat loss and overhunting.

2-10-2020 MONTE CORONA, VALENCIA - WAVE MOTH (idaea cervantaria)
1.4 to 2.2 cm wingspan. Straw-coloured, with yellowish wings with scattered dark, brown or greyish scales. On each wing it has a wavy line with small pointed spots, pointing backwards. Sometimes these details are barely noticeable. Between these lines and the rear edge, it has dark spots that may have a light wavy stripe. It has a spot on each wing but those on the front wings may go unnoticed.
There are other similar species that are impossible to distinguish externally, so for a correct and safe identification, genital analysis must be used. Several of them have been found in the province of Malaga, although I. cervantaria is currently the most common and the only one that has been observed in urban environments.
The caterpillars feed on dry leaves of herbaceous plants and in captivity on petals of different Asteraceae and sea alder (Lobularia maritima), the latter common in our province, especially in sunny areas of the limestone mountains, and occasionally used in gardening for the showiness of its inflorescences.

30-9-2020 EL HONDO, MURCIA - EURASIAN COOT (Fulica atra)
%2020.jpg)
The Eurasian coot, Fulica atra, also known as the common coot or Australian coot, is a distinctive waterbird with a slaty-black body, a glossy black head, and a striking white bill topped with a white frontal shield. This bird is a member of the Rallidae family, which includes rails and crakes. Both sexes exhibit similar plumage, making them indistinguishable in the field.
Adult Eurasian coots measure 36–38 cm in length with a wingspan of 70–80 cm. Males are slightly heavier than females, weighing around 890 g compared to the females' 750 g. The species is characterized by its white bill and frontal shield, which contrast sharply with its all-black body. Juveniles are paler with a whitish breast and lack the facial shield, which develops fully by one year of age.
%2021.jpg)
The Eurasian coot is found on freshwater lakes and ponds and has adapted well to urban environments, often seen in city parks and gardens with water bodies.
This bird has a broad range across the Old World, including Europe, Asia, Australia, New Zealand, and parts of North Africa. It is a resident in milder regions but migrates south and west from much of Asia during winter.
The Eurasian coot is less secretive than many rails, often visible on open water or grasslands. It is territorial and aggressive during the breeding season, with both parents defending their territory. In non-breeding seasons, coots may form large flocks. They are reluctant flyers, preferring to run across water surfaces, and are known for bobbing their heads while swimming.
1-10-2020 MONTE CORONA, VALENCIA - PUG MOTH (Eupithecia semigraphata)
Eupithecia semigraphata is a moth in the family Geometridae. It is found from most of Europe (except the Netherlands, Ireland, Great Britain, Denmark, Fennoscandia, the Baltic region and Portugal) to the Caucasus and Armenia. It is also present on the Canary Islands and North Africa.
The wingspan is about 18–20 mm. Adults are on wing from late June to August in one generation per year.
The larvae feed on the flowers of Calamintha (including Calamintha nepeta and Calamintha sylvatica), Hypericum, Origanum and Thymus species. The species overwinters in the pupal stage.
1-10-2020 MONTE CORONA, VALENCIA - YELLOW BELLE MOTH (Aspitates ochrearia)
%2020.jpg)
Aspitates ochrearia, the yellow belle, is a moth in the family Geometridae. The species was first described by Pietro Rossi in 1794. It is found in western and southern Europe, as well as North America.
The wingspan is 25–34 mm. Adults are on wing from April to June and again from August to September in two generations per year.
The larvae feed on various herbaceous plants, including Daucus carota and Plantago coronopus. The larvae can be found from April to June. The species overwinters in the larval stage. Pupation takes place in spring.
30-9-2020 MONTE CORONA, VALENCIA - GRASS EGGAR MOTH (Lasiocampa trifolii)
Lasiocampa trifolii, the grass eggar, is a moth of the family Lasiocampidae first described by Michael Denis and Ignaz Schiffermüller in 1775 and found in Europe.
It is found in Europe in coastal dunes.
Eggs are laid on leaves close to the ground, hatch in the autumn, and the young larvae hibernate. The larvae feed on grasses, various shrubs and deciduous trees, such as oak, European beech, poplar and Calluna.[citation needed] The cocoon is formed on the ground.
Adults' wingspan is 40–55 mm and it flies from June to September depending on the location (in Britain it is on the wing in August). They fly during the day, but also at night, and will come to a light. The female is larger than the male.
29-9-2020 MONTE CORONA, VALENCIA - JASMINE MOTH (Palpita vitrealis)
Palpita vitrealis, common name jasmine moth or white pearl, is a species of moth of the family Crambidae.
This species occurs worldwide, including Africa (Equatorial Guinea, Gambia, Kenya, Sierra Leone, South Africa),Asia, Australia and Europe. In Europe, it is mainly found in southern Europe, but may be found further north.
The wingspan of Palpita vitrealis can reach 27–31 mm. The body and the wings are translucent with a slight sheen. Eyes are large and reddish-brown. On the upper edge of the forewings is present a rather broad orange or brown border. The forewings also show two black spots in the middle. Legs are white and brown ringed.
These moths mainly fly from August till late October, depending on the location. They feed on nectar of various flowers, including ivy and buddleia. This species shows a migratory nature. The larvae are initially yellow, later becoming green. They can grow to a length of about 2 cms. They feed on the leaves of the host plants, mainly jasmine (Jasminum officinale), privet (Ligustrum species), Forsythia, Arbutus unedo and european olive (Olea europaea). In Africa the preferred host plants are Sida rhombifolia, Grewia, Helicteres isora, Schima noronhae and Randia scortechinii. The larvae are considered a pest of olive fields, as they attack the leaves and fruits. The final instar of the larvae spins some leaves together and form a silky cocoon to pupate.
30-9-2020 EL HONDO, MURCIA - 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.
Grasshoppers are in general polyphagous, eating vegetation from many different plant sources. Eyprepocnemis plorans feeds mainly on grasses and sedges. The female deposits an egg pod in the ground and the eggs hatch in the spring. The nymphs undergo five moults, becoming more similar to the adult insect at each developmental stage; they do not undergo metamorphosis and mature in the summer. In parts of the range many adults survive the winter. This species is rather wary and is a good flier.
The karyotype of this grasshopper includes a number of B chromosomes (extra chromosomes) and exhibits a very widespread polymorphism; populations in Spain show about 40 different variations in B chromosomes, resulting in an increase in the frequency of chiasmas.
During spermatogenesis in E. plorans, the autosomal chromosomes achieve complete synapsis, but the single X sex chromosome always remains unsynapsed. The autosomal chromosomes are transcriptionally active during the leptotene to zygotene stages of meiosis, whereas the X chromosome is inactive throughout meiosis likely because of specific epigenetic modifications.

30-9-2020 EL HONDO, MURCIA - YELLOW DOT ISOPOD (Porcellio ornatus)
Porcellio ornatus are, fast-breeding, large (up to 2.5 cm) Spanish isopods known for vibrant yellow-spotted, "High Yellow," and "Witch's Brew" color morphs. Popular for hobbyists due to their active, visible nature, they require dry, well-ventilated setups with 1/3-1/4 damp areas. They are excellent, non-picky cleaners but need high protein and calcium.
Key Facts & Care Information
Origin & Habitat: Native to Spain and North Africa (Tunisia), they prefer semi-arid environments, acting as a "dry-loving" species.Appearance: These are large, somewhat thin, and elongate isopods, often featuring high-yellow spots on a grayish, or in some localities (like "Nord"), white-skirted, base color.
Behavior: Unlike some shy species, P. ornatus are active during the day, frequently exploring their enclosure, making them excellent display animals. They tend to gather in groups.
