15-7-2025 AMSTERDAM ZOO, HOLLAND - ZEBRA LONGWING BUTTERFLY (Heliconius charithonia)

Heliconius charithonia, the zebra longwing or zebra heliconian, is a species of butterfly belonging to the subfamily Heliconiinae of the family Nymphalidae. It was first described by Carl Linnaeus in his 1767 12th edition of Systema Naturae. The boldly striped black and white wing pattern is aposematic, warning off predators. It is the state butterfly of Florida.

The species is distributed across South and Central America and as far north as southern Texas and peninsular Florida; there are migrations north into other American states in the warmer months.

Zebra longwing adults roost communally at night in groups of up to 60 adults for safety from predators. The adult butterflies are unusual in feeding on pollen as well as on nectar; the pollen enables them to synthesize cyanogenic glycosides that make their bodies toxic to potential predators. Caterpillars feed on various species of passionflower, evading the plants' defensive trichomes by biting them off or laying silk mats over them.

The zebra longwing, Heliconius charithonia (Linnaeus),was designated the state butterfly of Florida in 1996.  However, mass spraying of naled has decimated the zebra longwing population in Miami-Dade County, Florida. There has been mass collapse of the colonies with impacts on the balance of the ecosystem. Further studies are needed to evaluate any potential for recolonization.

15-7-2025 AMSTERDAM ZOO, HOLLAND - MOCKER SWALLOWTAIL BUTTERFLY (MALE ) (Papilio dardanus)

Papilio dardanus, the Saharan swallowtail, African swallowtail, mocker swallowtail or flying handkerchief, is a species of butterfly in the family Papilionidae (the swallowtails). The species is broadly distributed throughout Sub-Saharan Africa. The British entomologist E. B. Poulton described it as "the most interesting butterfly in the world".

Molecular studies have provided evidence that this species' closest relative is Papilio phorcas, with Papilio constantinus being the next closest (see images below). It is a member of the Papilio genus of which Papilio appalachiensis and Papilio xuthus are also members.

Papilio dardanus is the nominal member of the dardanus species group. The members of the clade are:

Papilio dardanus Brown, 1776

Papilio constantinus Ward, 1871

Papilio delalandei Godart, [1824]

Papilio phorcas Cramer, [1775]

Papilio rex Oberthür, 1886

15-7-2025 AMSTERDAM ZOO, HOLLAND - TIGER LONGWING BUTTERFLY (Heliconius hecale)

 Heliconius hecale, the tiger longwing, Hecale longwing, golden longwing or golden heliconian, is a heliconiid butterfly that occurs from Mexico to the Peruvian Amazon.

Tiger longwings (Heliconius hecale), can be found in Central America and further south in the Amazon. They are part of the most important tropical butterfly group for the study of diversity and genetics.

There are around 40 species in the Heliconius group, and they all have long wings with a variety of simple, striking patterns, often with a black background.

Longwings copy the patterns of more poisonous butterflies.

Each wing pattern has been tweaked by evolution to help the creature survive. Many of the longwings copy the patterns of related butterflies.

All the species thrive in the same range of environments and geographical areas. And the tiger longwings protect themselves from predators by mimicking the patterns of other, poisonous species very closely.

This mimicry changes depending on geographical area, but the tiger longwings are known to copy the ithomiine butterfly (Tithorea tarricina). Another black and orange species, it carries alkaloids in its body that make it distasteful to predators.

Birds end up avoiding both species because they are unable to spot the differences between them.

15-7-2025 AMSTERDAM ZOO, HOLLAND - PALE OWL BUTTERFLY (Caligo telamonius)

 Caligo telamonius is a brush-footed butterfly (family Nymphalidae). The species was first described by Cajetan von Felder and Rudolf Felder in 1862. It is found in southern North America, Central America, and South America.

Subspecies

Two subspecies belong to the species Caligo telamonius:

Caligo telamonius memnon

Caligo telamonius menus

15-7-2025 AMSTERDAM ZOO, HOLLAND - SILVER STUDDED LEAFWING BUTTERFLY (Hypna clytemnestra)

 Hypna is a butterfly genus of the family Nymphalidae. It is monotypic, containing only Hypna clytemnestra, the jazzy leafwing, marbled leafwing or silver-studded leafwing.

Hypna clytemnestra is the largest member of the tribe Anaeini. This "leafwing butterfly" is quite uncommon. The uppersides of the forewings are black, with a few white spots on the margins and two large white transverse bands. The uppersides of the hindwings are mainly brown. The undersides mimic dead leaves, ranging from dark brown to whitish. Larvae feed on Croton floribundus (Euphorbiaceae), while adults feed on rotting fruits.

Hypna clytemnestra can be found from Mexico to the Amazon basin.

This butterfly can be found in the lowlands or the foothills, at an elevation of about 100–1,200 metres (330–3,940 ft) above sea level.

16-7-2025 OOSTERPARK AMSTERDAM, HOLLAND - CARRION CROW (Corvus corone)

The Carrion Crow, Corvus corone, is a member of the Corvidae family and the genus Corvus. This bird is recognized by its entirely black plumage, which exhibits a green or purple sheen, particularly more vibrant than that of the Rook. The adult male, which can be seen moulting in places like the Jardin des Plantes in Paris, measures approximately 48–52 centimeters in length, with a wingspan ranging from 84 to 100 centimeters, and weighs between 400 and 600 grams. Juveniles display brownish feathers and blue eyes, which darken with age. To identify the Carrion Crow, look for its black bill, legs, and feet, which complement its dark plumage. It is smaller than the common raven and lacks the grey plumage of the hooded crow. When observing juveniles, note the brownish plumage and blue eyes, which will gradually change as the bird matures.

Carrion Crows are versatile in their choice of habitat. They can be found in urban areas, moorlands, woodlands, sea cliffs, and farmlands. They are often seen in proximity to human activity, where they can scavenge for food.

15-7-2025 AMSTERDAM ZOO, HOLLAND - GREY HERON

The Grey Heron (Ardea cinerea) is a statuesque wading bird belonging to the family Ardeidae. It is a familiar sight in both rural and urban settings, often seen standing stoically along the water's edge. An adult Grey Heron is a large bird, reaching up to 100 cm in height, with a wingspan between 155 to 195 cm. It weighs between 1 to 2 kg. The plumage is predominantly ashy-grey above, with a greyish-white underbelly and some black on the flanks. A striking feature is the white head and neck adorned with a broad black stripe that extends from the eye to the black crest. The beak is pinkish-yellow, long, and sharply pointed, while the legs are a brown hue.

When identifying the Grey Heron, look for the white head with the black supercilium and crest, the long grey neck, and the ashy-grey wings and back. The underparts are lighter, and the legs are long and brown. Juveniles can be distinguished by their duller grey neck and smaller crest. The beak is a useful indicator of age, being brighter in breeding adults.

Grey Herons are highly adaptable and can be found in a variety of watery habitats including lakes, rivers, ponds, marshes, and coastal environments. They require shallow waters for foraging or areas with shelving margins where they can wade.

15-7-2025 AMSTERDAM ZOO, HOLLAND - BURROWING OWL (Athene cunicularia)

The burrowing owl (Athene cunicularia), also called the shoco, is a small, long-legged, primarily terrestrial—though not flightless—species of owl native to the open landscapes of North and South America. They are typically found in grasslands, rangelands, agricultural areas, deserts, or any other open, dry area with low vegetation. They nest and roost in burrows, and, despite their common name, do not often construct these dwellings themselves, rather repurposing disused burrows or tunnels previously excavated and inhabited by other species, such as American badgers (Taxidea taxus), foxes (Vulpes sp.), ground squirrels or prairie dogs (Cynomys spp.), among others.

Unlike most owls, burrowing owls are often active during the day, although they tend to avoid the heat of midday. But, similar to many other species of owls, they are mostly crepuscular hunters, as they can utilize their night vision and attuned hearing to maximum potential during sunrise and sunset. Having evolved to live on open grasslands and prairie habitat (as well as badlands, chaparral and desert ecosystems), as opposed to dense forest, the burrowing owl has developed longer legs than other owls, a trait which enables it to sprint when pursuing its prey, not dissimilarly to the greater roadrunner, as well as providing momentum when taking flight; however, burrowing owls typically only become airborne for short bursts, such as when fleeing threats, and typically do not fly very high off of the ground.

The burrowing owl was formally described by Spanish naturalist Juan Ignacio Molina in 1782 under the binomial name Strix cunicularia from a specimen collected in Chile. The specific epithet is from the Latin cunicularius, meaning "burrower" or "miner". The burrowing owl is now placed in the genus Athene which was introduced by German zoologist Friedrich Boie in 1822.

The burrowing owl is sometimes classified in the monotypic genus Speotyto (based on an overall unique morphology and karyotype). Osteology and DNA sequence data, though, suggests that the burrowing owl is a terrestrial member of the little owls genus (Athene), thus it is placed in that group today, by most authorities.

A considerable number of subspecies have been described, though they differ little in appearance; the taxonomic validity of several is still up for debate. Most subspecies are found in or near the Andes and within the Antilles of the Caribbean Sea. Although distinct from each other, the relationship of the Florida subspecies, for instance, to (and its distinctness from) the Caribbean owls, is not quite clear.

15-7-2025 AMSTERDAM ZOO, HOLLAND - EURASIAN WREN (Troglodytes troglodytes)

The Eurasian wren (Troglodytes troglodytes), also known as the northern wren, is a diminutive bird, the sole representative of the wren family Troglodytidae found across Eurasia and Africa's Maghreb region. In Anglophone Europe, it is often simply referred to as the wren. This bird is characterized by its very short tail, typically held erect, a short neck, and a relatively long, thin bill. Its upperparts are russet brown, while the underparts are a paler buff-brown, complemented by a cream buff supercilium. Both sexes exhibit similar plumage.

The Eurasian wren can be identified by its compact, robust body, rounded wings, and notably short tail. It measures approximately 9 to 10 cm in length with a wingspan ranging from 13 to 17 cm, and weighs around 10 g. The plumage varies geographically, with some isolated populations exhibiting distinct coloration.

The Eurasian wren occupies a wide range of habitats, including cultivated and uncultivated areas with bushes and low ground cover, such as gardens, hedgerows, thickets, plantations, woodland, and reed beds. It is also found in more open spaces with bramble clumps or gorse, rough pastures, moorland, boulder-strewn slopes, rocky coasts, and sea cliffs.

This Palearctic species is widespread, with the nominate race breeding in Europe up to the northern latitudes of Norway and Sweden, and extending south to Spain, France, Italy, and southern Russia. It also breeds in Western Asia as far east as Syria and is represented by various subspecies across its range, including isolated island populations.

The Eurasian wren is a ceaselessly active forager, darting about in search of insects among dense vegetation or within crevices. It is known for its quick, jerky movements and propensity to stay close to the ground, often being flushed from under overhangs or banks. The wren may occasionally ascend to higher canopies but generally prefers lower strata near the ground.

15-7-2025 AMSTERDAM ZOO, HOLLAND - EMERALD ASH BORER (Agrilus planipennis)

The emerald ash borer (Agrilus planipennis), also known by the abbreviation EAB, is a green buprestid or jewel beetle native to north-eastern Asia that feeds on ash species (Fraxinus spp.). Females lay eggs in bark crevices on ash trees, and larvae feed underneath the bark of ash trees to emerge as adults in one to two years. In its native range, it is typically found at low densities and does not cause significant damage to trees native to the area. Outside its native range, it is an invasive species and is highly destructive to ash trees native to Europe and North America. Before it was found in North America, very little was known about the emerald ash borer in its native range; this has resulted in much of the research on its biology being focused in North America. Local governments in North America are attempting to control it by monitoring its spread, diversifying tree species, and through the use of insecticides and biological control.

15-7-2025 AMSTERDAM ZOO, HOLLAND - SUN BEETLE (Pachnoda marginata)

Pachnoda marginata is a beetle from the subfamily Cetoniinae with a large number of Pachnoda marginata is a beetle from the subfamily Cetoniinae with a large number of subspecies that lives in west and central Africa. They are sometimes used as food for terrarium animals. The adult beetles are 20–30 mm, the larvae are very small when they hatch, but can grow as long as 60 mm. (2.36 in.) It is commonly called the sun beetle or Congo chafer beetle.

The sun beetle comes in nine subspecies, the three common ones are: Pachnoda marginata aurantia, Pachnoda marginata marginata, Pachnoda marginata peregrina, with ranging colors. Pachnoda marginata aurantia comes from orange to a yellow-orange, some having a hue gradient towards the middle seen in diagram below. Pachnoda marginata marginata normally is red or crimson with little change between individuals. Pachnoda marginata peregrina, the more common amongst the subspecies, is a pale yellow or orange with brown spots; one spot being on the thorax and two spots on each elytra on each wing. that lives in west and central Africa. They are sometimes used as food for terrarium animals. The adult beetles are 20–30 mm, the larvae are very small when they hatch, but can grow as long as 60 mm. (2.36 in.) It is commonly called the sun beetle or Congo chafer beetle.

15-7-2025 AMSTERDAM ZOO, HOLLAND - LEMON PANSY BUTTERFLY

Junonia lemonias, the lemon pansy, is a common nymphalid butterfly found in Cambodia and South Asia. It is found in gardens, fallow land, and open wooded areas.

It is brown with numerous eyespots as well as black and lemon-yellow spots and lines on the upperside of the wings. The underside is a dull brown, with a number of wavy lines and spots in varying shades of brown and black. There is also an eyespot on the lower side of the forewing. The wet- and dry-season forms differ considerably in coloration and even shape. In the wet-season form the markings are distinct and vivid and the wing shape is a little more rounded. In the dry-season form the markings are obscure and pale especially on the underside and the wing margin is more angular and jagged. This helps it camouflage in the dried leaf litter.

The lemon pansy is a very active butterfly and can be seen basking with its wings open facing the sun. It sits very low to the ground and can be approached easily. It feeds with its wings half open. It is a fairly strong flier and flies close to the ground with rapid wingbeats and often returns to settle back in the same spots.

15-7-2025 AMSTERDAM ZOO, HOLLAND - CRIMSON PATCH BUTTERFLY (Chlosyne janais)

Chlosyne janais, the crimson patch or janais patch, is a common New World butterfly found from Colombia north through Central America and Mexico to southern Texas, with occasional sightings in southeastern Mexico and northern Texas. The dorsal and ventral wing surface is black with several undulating rows of small white spots on the medial forewings and along all outer wing margins. On each dorsal hindwing is a medial orange-red patch situated anteriorly. The ventral hindwings have a fragmented yellow proximal patch bordered by a thick postmedial band of red that does not reach the wing margins; maximum wingspan is 4.8–6.7 cm.

Adults inhabit the periphery of lowland tropical to subtropical forests, fields, and along streams, where they feed on flower nectar. Reproduction is continuous in the tropics, whereas in temperate areas several broods are produced from July to November. The caterpillars are grey white to green with several transverse rows of fleshly black spines; they feed primarily on acanthus shrubs, especially Anisacanthus wrightii and Odontonema callistachus (in Texas), upon which adult females lay their eggs.

The crimson patch can reach high numbers in the Rio Grande Valley, but the population is periodically killed off by cold snaps; the area is then recolonized by members of the Mexican population. A very similar species is the rosita patch (C. rosita), which is distinguished from the crimson patch by the former's lack of spots on the wing margins.

15-7-2025 AMSTERDAM ZOO, HOLLAND - LEMON MIGRANT BUTTERFLY (Catopsilia pomona)

Catopsilia pomona, the common emigrant or lemon emigrant, is a medium-sized pierid butterfly found in Asia and parts of Australia. The species gets its name from its habit of migration. Some early authors considered them as two distinct species Catopsilia crocale and Catopsilia pomona.

The species has pale and dark morphs in Australia. The form crocale has the antennae black and the form pomona has the antennae pinkish or red. The development of these forms has been linked to photoperiod and temperature during growth.

The eggs of the butterfly are laid on various species of plants including several Cassias. Other host plants include Butea monosperma, Cassia fistula, Bauhinia species, Pterocarpus indicus, Senna alata and Sesbania species. The eggs are usually laid singly on the underside, at the margin of the leaves. Each egg is white, bottle shaped, and ribbed vertically. The eggs hatch in 3–4 days.

15-7-2025 AMSTERDAM ZOO, HOLLAND - MALACHITE BUTTERFLY (Siproeta stelenes)

Siproeta stelenes (malachite) is a Neotropical brush-footed butterfly (family Nymphalidae). The malachite has large wings that are black and brilliant green or yellow-green on the upperside and light brown and olive green on the underside. It is named for the mineral malachite, which is similar in color to the bright green on the butterfly's wings. Typically, the wingspread is between 8.5 and 10 cm (3.3 and 3.9 in). The malachite is found throughout Central and northern South America, where it is one of the most common butterfly species. Its distribution extends as far north as southern Texas and the tip of Florida, to Cuba as subspecies S. s. insularis (Holland, 1916), and S. s. biplagiata, and south to Brazil.

Adults feed on flower nectar, rotting fruit, dead animals, and bat dung. Females lay eggs on the new leaves of plants in the family Acanthaceae, especially Ruellia. The larvae are horned, spiny, black caterpillars with red markings, The pupal stage is green, with sharp, gold spines that can puncture predators.

Malachites often are confused with the heliconiine Philaethria dido. They have similar coloration, but their wing shapes are different.

15-7-2025 AMSTERDAM ZOO, HOLLAND - CHOCOLATE PANSY BUTTERFLY (Junonia iphita)

Junonia iphita, the chocolate pansy or chocolate soldier, is a butterfly found in Asia.

The wingspan is about 5–6 cm (2.0–2.4 in) and the female can be told apart from the male by white markings on the oblique line on the underside of the hindwing. The wavy lines on the underside of the wings vary from wet- to dry-season forms.

Individuals maintain a territory and are usually found close to the ground level and often bask in the sun.

Upperside of both sexes brown of varying depths of colour. Forewing: cell with one pair of subbasal and one pair of apical transverse sinuous fasciae, the outermost defining the discocellulars; a short, broad, dark, oblique fascia beyond to vein 4, its inner margin diffuse, its outer sinuous but sharply defined; below vein 4 a sinuous, transverse, more faint fascia, followed by a discal blackish fascia, very broad and diffuse, below costa, bordered by a row of faint ocelli, and a postdiscal and a subterminal similar fascia following the outline of the termen. Hindwing with a slender blackish loop near apex of cellular area; a broad inwardly diffuse, outwardly well-defined short discal fascia in continuation of the one on the forewing; a series of postdiscal somewhat ochraceous ocelli with black pupils minutely centred with white; postdiscal and subterminal broad lines as on the forewing.

Underside brown, with very broad darker brown transverse fasciae, the interspaces between the markings irrorated (sprinkled) with purplish silvery scales. Forewing with two sinuous fasciae on basal half succeeded by a discal fascia, very broad at the costal margin and decreasing in width to the dorsum, bearing on its outer border a row of obscure ocelli. This is succeeded by a zigzag dark line, and sinuous subterminal and terminal lines; apex and tornal area suffused with purplish silvery. Hindwing: two irregular, very broad, dark brown, curved short fasciae near base; a straight, transverse, prominent, narrow ochreous-brown discal band defined outwardly by a black line; a transverse postdiscal dark brown fascia, widest in the middle and bearing outwardly a curved row of ochreous-brown white-centred ocelli, followed by a zigzag dark line in continuation of the one on the forewing; a subterminal somewhat diffuse dark fascia and a terminal dark line. Antennae, head, thorax and abdomen dark brown.

The eggs are often laid on the ground or on dry twigs near the host plants rather than on them. On hatching the larvae find their way to the host plants.

15-7-2025 AMSTERDAM ZOO, HOLLAND - ISABELLA'S LONGWING BUTTERFLY (Eueides isabella)

Eueides isabella, the Isabella's longwing or Isabella's heliconian, is a species of nymphalid butterfly, belonging to the Heliconiinae subfamily.

Eueides isabella is a large butterfly with a wingspan of 65–90 millimetres (2.6–3.5 in). The uppersides of the wings is dark brown, with orange bands and yellowish markings on the edges of the forewings. The undersides of the wings are quite similar to the uppersides, but the edges of the hindwings show a series of small blue spots.

The flight period extends to the whole year in the tropical habitat. They are active even in low light. Caterpillars are white and black covered by long black spines. They are gregarious and they primarily feed on Passiflora platyloba and Passiflora ambigua.

This species can be found from Mexico to the Amazon basin and the West Indies.

11-7-2025 MONTE CORONA, VALENCIA - FRENCH PAPER WASP (Polistes gallicus)

Polistes gallicus is a species of paper wasp found in various parts of Europe, excluding England, Denmark, and Scandinavia, from warmer climates to cooler regions north of the Alps. Nests of these social insects are created in these various conditions. The Polistes species use an oral secretion to construct their nests, which consist of a combination of saliva and chewed plant fibers. This structural mixture physically protects the nest from various harsh elements and from weathering over time.

P. gallicus, like other members of the subgenus Polistes (Polistes), has recognizable, bright yellow and black markings. They have smaller bodies than many of its allies that overlap in range, and their bodies are largely hairless. The species may be separated from allies through the following traits.

Females are identified by having 12 antennal segments and 6 abdominal segments. The antennae are orange and paler on the ventral surface than in many allies and have yellow-marked scapes. The malar space is short, under 0.75 times the distance between the lateral ocelli, and is black. They have slender mandibles that are mostly colored black with an excentric yellow spot on each. In contrast, the clypeus is yellow and often with a small but distinct black spot or band. As in many species within the subgenus, the mesoscutum has a pair of developed spots. Both the spots on the propodeum and continuous band on the fourth abdominal sternite are wide. Unlike species such as P. dominula, P. gallicus has a mostly black hypopygium.

Males are identified by having 13 antennal segments and 7 abdominal segments. The head is roughly triangular as viewed from the front with a curved clypeus. The apical half of the antennae is entirely orange-yellow, and the final segment is slightly under twice as long as wide. The pronotum has a yellow band that widens toward the sides as well as short, straight hairs. The mesosternum is largely yellow, more so than in some allies. Both the mesoscutum and scutellum typically have distinct spots. The abdomen has the final sternite entirely black.

10-7-2025 PARC DE SANT PERE GANDIA, VALENCA - 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.

With an upright posture, these flycatchers are often seen hunting from prominent perches, darting out to snatch flying insects and frequently returning to the same spot.

The call of the Spotted Flycatcher is a soft, high-pitched, and slightly descending 'tssssseeeeeppppp'.

The Spotted Flycatcher constructs an open nest in a recess, often against a wall, and is amenable to using open-fronted nest boxes. Clutches typically consist of 4-6 eggs. Remarkably, they exhibit excellent egg recognition, a likely evolutionary response to past parasitism by the common cuckoo.

The Mediterranean flycatcher, previously considered a subspecies, is similar in appearance but has been recognized as a separate species due to genetic differences.

As aerial insectivores, Spotted Flycatchers feed on flying insects, which they catch in mid-air from their vantage points.

10-7-2025 PARC DE SANT PERE GANDIA, VALENCA - EUROPEAN GREENFINCH (FEMALE) EUROPEAN GREENFINCH (Chloris chloris)

The European greenfinch, or simply greenfinch, is a small passerine bird belonging to the finch family Fringillidae. Exhibiting a predominantly green plumage with yellow accents on the wings and tail, the male is a vibrant sight, while the female and juveniles are more subdued with brownish tones. This bird measures approximately 15 cm in length with a wingspan ranging from 24.5 to 27.5 cm, resembling the size and shape of a house sparrow.

To identify the European greenfinch, look for its thick and conical bill, a characteristic of seed-eating birds. The male's plumage is a striking green with yellow flashes on the wings and tail, whereas the female and young birds are more muted with brownish backs. The male's display flight is akin to a butterfly, a dance to charm its mate.

The greenfinch favors woodland edges, farmland hedges, and gardens with dense vegetation for breeding. It nests in trees or bushes within these habitats.

This bird has a broad range across Europe, North Africa, and Southwest Asia. It is mainly sedentary, but some populations in the northernmost regions migrate southwards in colder months. The species has also been introduced to Australia, New Zealand, Uruguay, and Argentina.

The greenfinch is known for its social nature, often seen in flocks outside the breeding season. It exhibits a breeding season from March to June, with fledglings emerging in early July. The species is capable of producing multiple broods annually.

The song of the greenfinch is a delightful mix of trills and twitters, interspersed with distinctive wheezes, contributing to the rich tapestry of sounds in its natural environment.

The female greenfinch constructs the nest and incubates the eggs, typically laying 4-6 eggs per clutch. Eggs are incubated for about 13-14 days, with chicks being fed an insect larva-rich diet initially, followed by a seed paste as they grow.

Greenfinches have a varied diet consisting of seeds, berries, fruits, buds, flowers, and some arthropods. They forage in trees, bushes, and on the ground, adapting to available food sources.

The IUCN lists the European greenfinch as Least Concern, indicating a stable population despite some regional declines due to disease outbreaks.

10-7-2025 MONTE CORONA, VALENCIA - LEAFHOPPER ASSASIN BUG (Zelus renardii)

Zelus renardii, commonly known as the leaf hopper assassin bug, is a predacious insect contained within tribe Harpactorini. Diurnal and found on both wild and crop plants, Z. renardii has spread from its native habitats in western North and Central America into three other biogeographic regions across the globe.

Zelus renardii is considered a sister species to Z. cervicalis, as they share two unique characters: the lateral margins of dorsal phallothecal sclerite are recurved, and the medial process is strongly hooked apically.

The native range of Z. renardii extends over various climatic zones throughout mainland North and Central America at altitudes between 8m to 2000m above sea level. Native ranges include tropical, dry, semi-arid, arid, and Mediterranean climates. Additionally, Z. renardii also appears well suited to urban and disturbed areas, as it has been observed in suburban areas on both native and non-native herbaceous and woody plants, as well as common garden plants. Egg masses can frequently be found on vegetable plants. Z. renardii is also sympatric with Z. tetracantus over a large part of its range in western USA, Mexico, Guatemala, Jamaica, and other parts of Central America.

9-7-2025 MONTE CORONA, VALENCIA - EURASIAN RED SQUIRREL (Sciurus vulgaris)

The red squirrel (Sciurus vulgaris), also called Eurasian red squirrel, is a species of tree squirrel in the genus Sciurus. It is an arboreal and primarily herbivorous rodent and common throughout Eurasia.

The red squirrel has a typical head-and-body length of 19 to 23 cm (7.5 to 9.1 in), a tail length of 15 to 20 cm (5.9 to 7.9 in), and a mass of 250 to 340 g (8.8 to 12.0 oz). Males and females are the same size.[8]

The long tail helps the squirrel to balance and steer when jumping from tree to tree and running along branches and may keep the animal warm during sleep.

The coat of the red squirrel varies in colour with time of year and location. There are several coat colour morphs ranging from black to red. Red coats are most common in Great Britain; in other parts of Europe and Asia different coat colours coexist within populations, much like hair colour in some human populations. The underside of the squirrel is always white-cream in colour. The red squirrel sheds its coat twice a year, switching from a thinner summer coat to a thicker, darker winter coat with noticeably larger ear-tufts (a prominent distinguishing feature of this species) between August and November. A lighter, redder overall coat colour, along with the ear-tufts in adults and smaller size, distinguish the red squirrel from the eastern grey squirrel.

Red squirrels occupy boreal, coniferous woods in northern Europe and Siberia, preferring Scots pine, Norway spruce and Siberian pine. In western and southern Europe they are found in broad-leaved woods where the mixture of tree and shrub species provides a better year-round source of food. In most of the British Isles and in Italy, broad-leaved woodlands are now less suitable due to the better competitive feeding strategy of introduced grey squirrels.

In Great Britain, Ireland and in Italy, red squirrel populations have decreased in recent years. This decline is associated with the introduction by humans of the eastern grey squirrel (Sciurus carolinensis) from North America. However, the population in Scotland is stabilising due to conservation efforts.

The red squirrel is found in both coniferous forest and temperate broadleaf woodlands. The squirrel makes a drey (nest) out of twigs in a branch-fork, forming a domed structure about 25–30 cm (9.8–11.8 in) in diameter. This is lined with moss, leaves, grass and bark. Tree hollows and woodpecker holes are also used. The red squirrel is a solitary animal and is shy and reluctant to share food with others. However, outside the breeding season and particularly in winter, several red squirrels may share a drey to keep warm. Social organization is based on dominance hierarchies within and between sexes; although males are not necessarily dominant to females, the dominant animals tend to be larger and older than subordinate animals, and dominant males tend to have larger home ranges than subordinate males or females.

The red squirrel eats mostly the seeds of trees, neatly stripping conifer cones to get at the seeds within, fungi, nuts (especially hazelnuts but also beech, chestnuts and acorns), berries, vegetables, garden flowers, tree sap and young shoots. More rarely, red squirrels may also eat bird eggs or nestlings. A Swedish study shows that out of 600 stomach contents of red squirrels examined, only 4 contained remnants of birds or eggs.

Excess food is put into caches called "middens", either buried or in nooks or holes in trees, and eaten when food is scarce. Although the red squirrel remembers where it created caches at a better-than-chance level, its spatial memory is substantially less accurate and durable than that of grey squirrels. Between 60% and 80% of its active period may be spent foraging and feeding. The red squirrel exhibits a crepuscular activity pattern. It often rests in its nest in the middle of the day, avoiding the heat and the high visibility to birds of prey that are dangers during these hours. During the winter, this mid-day rest is often much briefer, or absent entirely, although harsh weather may cause the animal to stay in its nest for days at a time.

No territories are claimed between the red squirrels and the feeding areas of individuals overlap considerably.

9-7-2025 MONTE CORONA, VALENCIA - SATIN WAVE MOTH (Idaea subsericeata)

Idaea subsericeata, the satin wave, is a moth of the family Geometridae. The species was first described by Adrian Hardy Haworth in 1809. It is found from central and southern Europe, North Africa, Asia Minor to Transcaspia.

The species has a wingspan of 22–25 mm. The adults fly in one generation from June to July 

The ground colour is white with strong silky gloss, the lines grey, seldom strongly expressed, on the other hand usually all present, thus numbering five on the forewing and four on the hindwing; the outermost line (distal shading of subterminal) the oftenest absent; all except the median are parallel with the distal margin, but slightly wavy; the median on the forewing is usually somewhat oblique, but occasionally almost parallel with the others; that of the hindwing runs straighter across the wing, instead of following the curve of the strongly convex distal margin. Cellspots and terminal line wanting or rarely the former present, minute; fringe usually with a series of minute black dots at the base, which are sometimes in part, more rarely entirely obsolete. Forewing beneath often with a smoky suffusion, either basally or all over; median and postmedian lines present, often well developed; a small discal dot present. Hindwing beneath white, with discal dot and postmedian line. Male antennal ciliation little longer than diameter of shaft; hindtarsus short. Not on the whole an extremely variable species, except in size; there is, however, a great deal of trivial variation, i.e. as regards the absolute or relative strength of the several lines, the close proximity of the inner subterminal to the postmedian or their wider separation, the degree of suffusion of the under surface, etc. Second-brood specimens, besides being smaller seem to be on an average whiter beneath and are sometimes rounder winged. The oval egg has a depression in the middle of the upper end. The surface has small, flat recesses. It is initially light yellow and later turns bright orange with red spots.The caterpillar is relatively slender, the diameter decreasing a little at the front end. It is whitish grey, grey, grey-brown or brown and shows a slightly reddish dorsum. The surface looks wrinkled and is studded with fine warts. The dorsal line is relatively narrow, dark and is lined with dark dots. The lateral lines are yellowish white. The large head has a notch in the middle of the apex.The pupa is blackish brown to golden brown with greenish wing-sheaths . It is nine millimeters long and measures 2.9 millimeters in diameter. The cremaster is about as long as wide and is studded with four pairs of hook-shaped curved bristles.
