6-9-2020 GANDIA MARJAL, VALENCIA - LITTLE EGRET (Egretta garzetta)

The Little Egret, Egretta garzetta, is a dainty heron adorned in pure white plumage. It is characterized by a slender black beak, long black legs, and, notably in the western race, yellow feet. This elegant bird is a sight to behold with its graceful neck and poised stance.

Adult Little Egrets measure between 55–65 cm in length with a wingspan of 88–106 cm, and weigh 350–550 g. Their plumage is predominantly white, though some may exhibit bluish-grey coloration. Breeding adults boast ornate nape plumes reaching about 150 mm, along with distinctive feathers on the breast and elongated scapulars. 

The bill and lores are black, with greenish-grey skin at the base of the lower mandible and around the eye, which houses a yellow iris. Legs are black with contrasting yellow feet, though juveniles may have greenish-black legs and duller feet. The subspecies E. g. nigripes is distinguished by yellow skin between the bill and eye, and blackish feet. 

6-9-2020 GANDIA MARJAL, VALENCIA - RED EARED SLIDER TERRAPIN (Trachemys scripta ssp. elegans)

The red-eared slider or red-eared terrapin (Trachemys scripta elegans) is a subspecies of the pond slider (Trachemys scripta), a semiaquatic turtle belonging to the family Emydidae. It is the most popular pet turtle in the United States, is also popular as a pet across the rest of the world, and is the most invasive turtle. It is the most commonly traded turtle in the world.

The red-eared slider is native from the Midwestern United States to northern Mexico, but has become established in other places because of pet releases, and has become invasive in many areas where it outcompetes native species. The red-eared slider is included in the list of the world's 100 most invasive species.

Invasive red-eared sliders cause negative impacts in the ecosystems they are introduced to because they have certain advantages over the native populations, such as a lower age at maturity, higher fecundity rates, and larger body size, which gives them a competitive advantage at basking and nesting sites, as well as when exploiting food resources. They also transmit diseases and displace the other turtle species with which they compete for food and breeding space.

Owing to their popularity as pets, red-eared sliders have been released or escaped into the wild in many parts of the world. This turtle is considered one of the world's worst invasive species. Feral populations are now found in Bermuda, Canada, Australia, Europe, Great Britain, South Africa, the Caribbean Islands, Israel, Bahrain, the Mariana Islands, Guam, Russia, and south- and far-east Asia. Within Great Britain, red-eared sliders have a wide distribution throughout England, Scotland, and Wales.

In Australia, it is illegal for members of the public to import, keep, trade, or release red-eared sliders, as they are regarded as an invasive species – see below. Their import has also been banned by the European Union as well as specific EU member countries. In 2015, Japan announced it was planning to ban the import of red-eared sliders, but it would probably not take effect until 2020.

https://www.inaturalist.org/observations/58832431

6-9-2020 GANDIA MARJAL, VALENCIA - HOUSE SPARROW (FEMALE) (Passer domesticus)

The house sparrow (Passer domesticus) is a member of the sparrow family Passeridae. This small bird typically measures around 16 cm (6.3 in) in length and weighs between 24–39.5 g (0.85–1.39 oz). The species exhibits sexual dimorphism, with females and young birds displaying pale brown and grey plumage, while males are characterized by more vibrant black, white, and brown markings.

Males can be identified by their bright black, white, and brown markings, with a distinctive black bib, white cheeks, and a grey crown. Females lack the striking head patterns of males and are predominantly buffish with softer coloration. Juveniles resemble adult females but are generally paler with less defined markings.

The house sparrow is highly adaptable and can thrive in both urban and rural environments. It is commonly found in close association with human habitation and avoids dense forests, grasslands, polar regions, and deserts far from human development.

Native to Europe, the Mediterranean Basin, and much of Asia, the house sparrow has been introduced to various regions worldwide, including parts of Australasia, Africa, and the Americas, making it one of the most widely distributed wild birds.

House sparrows are social birds, often seen in flocks. They exhibit a range of behaviors, including dust or water bathing and communal roosting. Males are known to be territorial around their nesting sites.

The house sparrow's vocalizations are predominantly variations of a simple chirping call. Males may sing or give an "ecstatic call" during the breeding season, and the species uses a variety of calls for different social interactions.

House sparrows are generally monogamous and may mate for life. They can breed in the season following their hatching and often produce multiple clutches per year, with each clutch containing up to five eggs. Nest sites are varied, with a preference for cavities.

The house sparrow can be confused with other seed-eating birds, such as the Eurasian tree sparrow, which has a chestnut crown and a black cheek patch.

An opportunistic feeder, the house sparrow's diet consists mainly of seeds from grains and weeds, but it also consumes insects and other invertebrates, especially during the breeding season when feeding young.

Despite its widespread distribution and abundance, the house sparrow has experienced declines in some areas. However, it is currently listed as Least Concern on the IUCN Red List.

23-5-2019 MANA POOLS, ZIMBABWE - SPOTTED HYENA (Crocuta crocuta)

The spotted hyena (Crocuta crocuta), also known as the laughing hyena, is a hyena species, currently classed as the sole extant member of the genus Crocuta, native to sub-Saharan Africa. It is listed as being of least concern by the IUCN due to its widespread range and large numbers estimated between 27,000 and 47,000 individuals. The species is, however, experiencing declines outside of protected areas due to habitat loss and poaching. Populations of Crocuta, usually considered a subspecies of Crocuta crocuta, known as cave hyenas, roamed across Eurasia for at least one million years until the end of the Late Pleistocene. 

The spotted hyena is the largest extant member of the Hyaenidae, and is further physically distinguished from other species by its vaguely bear-like build, rounded ears, less prominent mane, spotted pelt, more dual-purposed dentition, fewer nipples, and pseudo-penis. It is the only placental mammalian species where females have a pseudo-penis and lack an external vaginal opening.

6-9-2020 LA FONT EN CARROS, VALENCIA - SPOTTED FLYCATCHER (Muscicapa striata)

The Spotted Flycatcher, Muscicapa striata, is a modestly adorned yet charming small passerine bird belonging to the Old World flycatcher family. It is a migratory species, breeding across Europe and the Palearctic as far as Siberia, and spending the winter months in Africa and southwestern Asia. Despite its widespread presence, there is concern over its decline in certain areas.

Adult Spotted Flycatchers possess grey-brown upperparts and a somewhat pallid underbelly. Their crown and breast are streaked, which is the origin of their common name. They have short, black legs and a black bill shaped to suit their insectivorous diet. Juveniles can be distinguished by their browner plumage and the presence of spots on their upperparts.

These birds favor deciduous woodlands, parks, and gardens, particularly those with open spaces amidst trees.

The Spotted Flycatcher has a broad breeding range, extending from Europe to western Siberia and northwest Africa. During the non-breeding season, they migrate to southern Africa.

6-9-2020 VILLALONGA RESERVOIR, VALENCIA - WHITE FEATHERLEG DAMSELFLY (Platycnemis latipes)

https://www.inaturalist.org/taxa/109646-Platycnemis-latipes

6-9-2020 VILLALONGA RESERVOIR, VALENCIA - WILD BOAR (JUVENILE) (Sus scrofa)

The wild boar (Sus scrofa), also known as the wild swine, common wild pig, Eurasian wild pig, or simply wild pig, is a suid native to much of Eurasia and North Africa, and has been introduced to the Americas and Oceania. The species is now one of the widest-ranging mammals in the world, as well as the most widespread suiform. It has been assessed as least concern on the IUCN Red List due to its wide range, high numbers, and adaptability to a diversity of habitats. It has become an invasive species in part of its introduced range. Wild boars probably originated in Southeast Asia during the Early Pleistocene and outcompeted other suid species as they spread throughout the Old World.

As of 2005, up to 16 subspecies are recognized, which are divided into four regional groupings based on skull height and lacrimal bone length. The species lives in matriarchal societies consisting of interrelated females and their young (both male and female). Fully grown males are usually solitary outside the breeding season. The wolf is the wild boar's main predator in most of its natural range except in the Far East and the Lesser Sunda Islands, where it is replaced by the tiger and Komodo dragon respectively. The wild boar has a long history of association with humans, having been the ancestor of most domestic pig breeds and a big-game animal for millennia. Boars have also re-hybridized in recent decades with feral pigs; these boar–pig hybrids have become a serious pest wild animal in the Americas and Australia.

4-9-2020 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.

4-9-2020 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.

5-9-2020 VILLALONGA RESERVIOR, VALENCIA - COPPER DEMOISELLE DAMSELFLY (FEMALE) (Calopteryx haemorrhoidalis)

Calopteryx haemorrhoidalis is a species of damselfly in the family Calopterygidae known by the common names copper demoiselle and Mediterranean demoiselle.

This species is native to the western Mediterranean Basin in Europe (Iberia, southern France, Italy, Monaco) and North Africa (Algeria, Morocco, Tunisia). It is common in much of its range.

It lives along rivers and streams, but also in sunny larger waters. Though it may be affected by habitat changes such as water pollution.

Calopteryx haemorrhoidalis can reach a body length of about 45–48 millimetres (1.8–1.9 in). The abdomen length is of about 34–43 millimetres (1.3–1.7 in) in males, of 31–43 millimetres (1.2–1.7 in) in females. The length of the wings is of 23–32 millimetres (0.91–1.26 in) in males, of 25–37 millimetres (0.98–1.46 in) in the females.

The males have a dark, metallic shining body, the color of which can be red-violet, golden or copper-colored. On the underside of the last three abdominal segments there red area, the so-called "red lantern" (hence the Latin species name haemorrhoidalis, meaning "blood flow"). The wings of males show a large dark area, while the females have a brown band to the wing tip and a metallic-green to bronze-colored body, with a brown belt on the back.

The flight time of this species ranges from May to September. The males have a characteristic mating dance, showing the abdomen end and spreading their wings wide. The male of this species is territorial, defending sites where females may choose to lay eggs.

This species can hybridize with Calopteryx splendens.

1-9-2020 PARADOR TERUEL, ARAGON - CATALONIA WALL LIZARD (Podarcis liolepis)

The Catalonian wall lizard (Podarcis liolepis), often called the Columbretes wall lizard or sargantana bruna, is a slender, 15–20 cm long reptile native to Northeast Spain and Southern France. Known for being highly adaptable, these brownish, long-tailed lizards thrive on rocks, walls, and in human settlements from sea level to 2000m in the Pyrenees. 

Key Facts About the Catalonian Wall Lizard:

Appearance: They are slender with long tails (roughly two-thirds of total length) and narrow, tapered heads. Their color is usually grey-brown, often with faint, reticulated, or striped patterns, especially in females.

Habitat: They prefer sunny areas and are found in rocky areas, dry-stone walls, and buildings. They are highly adapted to climbing.

Distribution: Primarily found in Catalonia (Spain), extending to the Columbretes Islands and parts of Southern France.

Diet: They are insectivores, feeding on insects such as crickets and grasshoppers.

Behavior: They are diurnal (active during the day).

Subspecies: Significant variability exists, with identified forms like P. liolepis cebennensis (Southern France) and P. liolepis atratus (Columbretes Archipelago).

Status: Classified as "Least Concern" (LC) by the IUCN, though they face threats from habitat alteration.

Distinction: Formerly considered a subspecies of the Iberian wall lizard (Podarcis hispanicus), it is now recognized as a distinct species. 

4-9-2020 MONTE CORONA, VALENCIA - JUMPING SPIDER (Menemerus semilimbatus)

Menemerus 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 in 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.

Menemerus semilimbatus is a jumping spider, and jumping spiders are venomous, according to WebMD and Healthline. However, their venom is not considered dangerous to humans. While they can bite if they feel threatened, their venom is generally not strong enough to cause serious illness. 

3-9-2020 MONTE CORONA, VALENCIA - BROAD SCARLET DRAGONFLY (FEMALE) (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. 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.

A wide range of both running and standing waters, except those that are shaded. Adults may be found some distance from water in habitats ranging from desert to open woodland; absent from dense forest.

Crocothemis erythraea can reach a length of 33–44 millimetres (1.3–1.7 in). These dragonflies haves a flattened and rather broad abdomen. The adult male scarlet dragonfly has a bright scarlet red, widened abdomen, with small amber patches at the bases of the hindwings. Also the veins on the leading edges of the wings are red. Females and immatures are yellow-brown and have a conspicuous pale stripe along the top of the thorax.

https://www.inaturalist.org/taxa/49133-Vanessa-atalanta

1-9-2020 PARADOR TERUEL, ARAGON - CONTINENTAL STRIPED SHIELD BUG (Graphosoma italicum ssp italicum)

Graphosoma italicum italicum (often called the Italian striped bug or minstrel bug) is a 8–12 mm shield bug characterized by bright red and black longitudinal stripes, black antennae, and black legs. Common across Europe, it inhabits warm, sunny areas, feeding on Apiaceae (carrot family) plants and acting as aposematic to deter predators with its bad taste.

Key Facts on Graphosoma italicum italicum

Appearance: The body is almost circular with a large shield, featuring bright red ground color with six bold black bands on the pronotum.

Leg Color: A distinguishing feature of G. italicum is its mostly black legs, separating it from the similar G. lineatum, which has red legs.

Diet and Habitat: They are common in sunny, dry meadows and prefer feeding on the flowers of Apiaceae (umbellifers) such as fennel and wild carrot.

Behavior & Protection: Their vibrant red and black stripes serve as aposematic coloration (warning signals), indicating a foul taste to predators.

Life Cycle: They have one generation a year. Females lay about thirty yellowish, barrel-shaped eggs on vegetation.

Nymphs: Nymphs do not have the striped red/black pattern; they are generally brownish or grayish.

Geographical Range: Primarily in South Europe, though they are expanding north, with breeding populations recently found in the UK.

Distinction: Previously considered a subspecies of G. lineatum, it is now recognized as a distinct species (G. italicum), with G. italicum italicum being the common European form.

Pest Status:While mainly feeding on wild plants, they can occasionally cause damage to cultivated carrots and fennel by sucking plant fluids, leading to reduced plant vigor.

1-9-2020 LAGUNA DEL CANIZAR, ARAGON - EUROPEAN STONECHAT (FEMALE) (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.

This species is widely distributed across Europe, reaching as far east as Ukraine and the South Caucasus, and can also be found in parts of North Africa.

Stonechats are known for their lively presence, often perching conspicuously as they keep a vigilant eye on their surroundings. They exhibit a partial migratory pattern, with some populations moving southward to escape the colder winters.

The male stonechat's song is a delightful, high-pitched twitter, reminiscent of a dunnock's melody. Both sexes communicate with a distinctive call that evokes the sound of two stones being tapped together.

European stonechats are monogamous during the breeding season and commence their reproductive efforts at one year of age. They raise two to three broods per season, with the female constructing the nest and both parents tending to the young.

The European stonechat can be confused with the Siberian stonechat and the African stonechat, but genetic evidence supports their distinction as separate species.

These birds are adept insectivores, gleaning a variety of invertebrates from their environment to sustain themselves and their offspring.

1-9-2020 LAGUNA DEL CANIZAR, ARAGON - GREAT CRESTED GREBE (Podiceps cristatus)

The great crested grebe (Podiceps cristatus) is a member of the grebe family of water birds. The bird is characterised by its distinctive appearance, featuring striking black and white plumage, and elaborate courtship display that involves synchronised dances and displays.

The great crested grebe is the largest member of the grebe family found in the Old World, with some larger species residing in the Americas. They measure 46–51 cm (18–20 in) long with a 59–73 cm (23–29 in) wingspan and weigh 0.9 to 1.5 kg (2.0 to 3.3 lb).[8][9] It is an excellent swimmer and diver, and pursues its fish prey underwater. The adults are unmistakable in summer with head and neck decorations. In winter, this is whiter than most grebes, with white above the eye, and a pink bill.

The call is a loud barking rah-rah-rah. They can also produce a clicking kek call, and deep growls.

Juveniles are recognisable by their plumage, with their heads featuring alternating black and white stripes. They lose these markings when they become adults.

The great crested grebe feeds mainly on fish, but also small crustaceans, insects, small frogs and newts.

The great crested grebe has an elaborate mating display. Like all grebes, it nests on the water's edge. The nest is built by both sexes. The clutch averages four chalky-white eggs which average 54 mm × 37 mm (2.1 in × 1.5 in) in size and 42 g (1.5 oz) in weight. Incubation is by both parents and begins as soon as the first egg is laid. The eggs hatch asynchronously after 27 to 29 days. The precocial young are cared for and fed by both parents.

Young grebes are capable of swimming and diving almost at hatching. The adults teach these skills to their young by carrying them on their back and diving, leaving the chicks to float on the surface; they then re-emerge a few feet away so that the chicks may swim back onto them.

1-9-2020 SAN BLAS TERUEL, ARAGON - WESTERN BLACK-EARED WHEATEAR (Oenanthe hispanica)

The western black-eared wheatear (Oenanthe hispanica) is a wheatear, a small migratory passerine bird that was formerly classed as a member of the thrush family Turdidae, but is now considered to be an Old World flycatcher (family Muscicapidae). It was formerly (and still is by some authorities) considered conspecific with the eastern black-eared wheatear.

The breeding male has the forehead and crown white or nearly white, the mantle buff, and the wings blacker than those of the northern wheatear. The underparts are white tinged with buff. The back, upper tail coverts and most of the tail are white. A black mask extends from the ear coverts to the bill. The throat can be either black or white.

In autumn and winter the head and mantle are distinctly buff, as are the underparts (including the throat in non-black-throated individuals), but the buff varies in intensity. Except for the central pair, the tail feathers are much whiter than in the northern wheatear, the white on the inner web often extending to the tip.

The female is a browner bird, but has the characteristic white lower back, and her seasonal changes are less marked.

The male western black-eared wheatear can be distinguished from the male eastern black-eared wheatear by its more buff-tinged upperparts, giving it a less distinctly black-and-white appearance than the latter species, as well as having the black of the mask stopping at the base of the bill rather than extending slightly above. Black-throated individuals of this species have less black on the throat and face than on the eastern birds, and the black generally terminates less abruptly. Females of this species differ from their eastern counterparts in being warmer brown overall.

Global Distribution: The Western Black-eared Wheatear breeds in Southwestern and South-central Europe (including Spain) and Northwestern Africa. The Eastern Black-eared Wheatear breeds in Southeastern Europe, Asia Minor, and the Middle East.

Migration: Both are strongly migratory species, with the Western populations wintering in the West African Sahel and Eastern populations wintering primarily in East Africa.Habitat Preference: Both prefer open, rocky habitats, sparse grasslands, and scrublands, making sightings common in Mediterranean biomes.

2-9-2020 SIERRA DE ALBARRACIN, ARAGON - SOUTHERN WHITE ADMIRAL BUTTERFLY (Limenitis reducta)

Limenitis reducta, the southern white admiral, is a butterfly of the family Nymphalidae.

Subspecies

Limenitis reducta reducta Staudinger, 1901

Limenitis reducta herculeana Stichel, 1909

 

This species can be found in central and southern Europe (northern Iberia, southern and eastern France, Italy, the Balkans, and the Alps), in Western Asia, in Syria, the Caucasus and Iran. These butterflies live in light woodland, in woodland glades and in forest edge, at an elevation of 0–1,650 metres (0–5,413 ft) above sea level.

Limenitis reducta has a wingspan of 46–54 mm. The upperside of the wings is brown black with metallic blue shine, large transversal band of white markings and a submarginal line of small blue dots. The blue sheen varies with the angle of light. The ground colour of underside of the hindwings is red, with a silvery basal area, a row of white markings and a row of black spots. A few white cell spots are also present on the underside of the forewings. The caterpillars can reach a length of 27 millimetres (1.1 in). They are light green to dull green on the back, red brown on the underside. On the back there are numerous brown thorns.

This species is rather similar to Limenitis camilla, Neptis rivularis and Araschnia levana f. prorsa.

2-9-2020 SIERRA DE ALBARRACIN, ARAGON - GRAYLING BUTTERFLY (Hipparchia semele)

The Grayling butterfly (Hipparchia semele) is a medium-sized, highly camouflaged insect found across Europe. It prefers warm, sunny, and dry habitats with sparse vegetation and plenty of bare ground, such as sand dunes and heathlands.

Key Identification & Behavior

Camouflage: It is renowned for its "rock-like" mottled-brown underwings. When at rest, it keeps its wings closed, tilts its body to avoid casting a shadow, and tucks its forewings behind its hindwings to hide its eyespots.

Sunbathing: Rather than nectaring on flowers frequently, adults spend much of their time basking on bare stones or soil, angling their wings to absorb maximum heat.

Flight Style: It is a strong flyer with a distinctive looping and gliding pattern. While in flight, pale yellow-orange bands on the upper wings become visible.

Life CycleFlight Period: The adult butterflies are typically on the wing from July to early September.Eggs & Larvae: Spherical white eggs are laid singly on fine-leaved grasses growing in direct sunlight. The larvae feed at night, spending the winter hibernating in grass tussocks before maturing by June.

Pupation: Unlike many butterflies that attach to stems, the Grayling pupates in a silk-lined cavity just beneath the soil's surface.

Conservation StatusHabitats: While still widespread on coastlines and southern heaths, inland populations have suffered long-term severe declines due to habitat loss and changing land use.
