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


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

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

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

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

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


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

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

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

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


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

12-9-2023 BOLOGNA, ITALY - EUROPEAN WALL LIZARD (Podarcis muralis)

Podarcis muralis (common wall lizard) is a species of lizard with a large distribution in Europe and well-established introduced populations in North America, where it is also called the European wall lizard. It can grow to about 20 cm (7.9 in) in total length. The animal has shown variation in the places it has been introduced to. Fossils have been found in a cave in Greece dating to the early part of the Holocene.


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

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

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

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

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


9-9-2023 MONTE CORONA, VALENCIA - PREDACEOUS WASP (genus Liris)


Liris is a genus of solitary, ground-nesting, predaceous wasps, containing over 300 species. It contains two subgenera: Leptolarra and Motes, with most of the species falling within subgenus Leptolarra.


9-9-2023 MONTE CORONA, VALENCIA - COMMON MAQUIS GRASSHOPPER (Pezotettix giornae)


Pezotettix giornae is a species of 'short-horned grasshoppers' belonging to the subfamily Pezotettiginae (similar to and previously placed in the Catantopinae).

This very little grasshopper is present in Southern Europe (and parts of Central Europe), North Africa and in the Near East.

Pezotettix giornae, mating couple
This species inhabits meadows of lowlands, forest edges, xerotherm areas of plains and southern slopes of stony mountains.

The adult males grow up to 11–14 millimetres (0.43–0.55 in) long, while the females reach 12–18 millimetres (0.47–0.71 in) of length. The basic coloration of the body varies from light brown to greyish. The eyes are relatively large and the sides of thorax sometimes show a white or darker longitudinal stripe. The wings are scaly, oval, very short, reaching only the middle of the second rear segment, so they are unable to fly and resemble nymphs (brachyptery). Nymphs are usually green in the early stages.

This immature stages of this species develop in summer, passing through six instars. Adults can be encountered from June through November in the Mediterranean. They mate in autumn and in winter and often overwinter as adults. In this case they can be found by March.

9-9-2023 MONTE CORONA, VALENCIA - ROUGH HAIRED LAGRIA BEETLE (Lagria hirta)


 Lagria hirta is a species of beetles in the family Tenebrionidae.

The species name hirta comes from the Latin hirtus meaning rough hair or rough wool, referring to the coarse, fuzzy appearance of the beetle.

This species is present in Europe, in North Africa (Algeria, Morocco), in Russia (Western and Eastern Siberia), in Israel, Turkey, Iran, Iraq, Paraguay, South America Kazakhstan, Turkmenistan, Uzbekistan and Tajikistan.

It prefers areas with sandy soils. It can be found in open woods, in deciduous forests, in forest clearings, forest edges, in grasslands and wet meadows, but also in dry valleys and wet areas.

Lagria hirta can reach a length of 7–8 millimetres (0.28–0.31 in). These beetles have a soft and elongated body and a head and thorax brown or shiny black. The relatively elongated elytra are yellowish-brown and covered by dense fine light yellowish-brown hairs. The rest of the body is also hairy, but they are less clearly visible. Antennae, underside of body and legs are black. The eyes are remarkably large and round. Antennae are composed with eleven segments.

The elytra of the females are more extended backward than in the males and the female's abdomen looks from above wider than in the males. The male, in addition to its slimmer body, is distinguished from the females by their larger eyes and by the length of the last segment of the antennae, which is nearly twice the corresponding segment in the female. The hind wings are transparent.

The fully formed beetles can be seen from late May to September. The adult beetles feed on nectar and pollen. Females lay the eggs in the soil where they hatch after about eight days. The larvae live in the humus where they feed on decaying vegetables. After having overwintered larvae pupate in early summer of the next year and a new generation of beetles will then developed.

9-9-2023 MONTE CORONA, VALENCIA - COMMON VERVAIN (Verbena officinalis)


Verbena officinalis, the common vervain or common verbena, is a perennial herb native to Europe. It grows up to 70 cm high, with an upright habitus. The lobed leaves are toothed, and the delicate spikes hold clusters of two-lipped mauve flowers.

This plant prefers limey soils; it is occasionally grown as an ornamental plant but perhaps more often for the powerful properties some herbalists ascribe to it. Propagation is by root cuttings or seed. It is widely naturalised outside its native range, for example in North America.

Common vervain has been held in high esteem since classical antiquity; it has long been associated with divine and other supernatural forces, and it has an equally long-standing use as a medicinal plant. Herbal capsules are used as a soporific drug in much the same way as for the better known valerian.

Verbena officinalis herb has been used in the traditional Austrian medicine internally (as tea or liqueur) for treatment of infections and fever. Medical use of Common Vervain is usually as a herbal tea; Nicholas Culpeper's 1652 The English Physitian discusses folk uses. "Vervain", presumably this species, is one of the original 38 Bach flower remedies, prescribed against "over-enthusiasm". In the modern era, it is sometimes considered a powerful "ally" of poets and writers, as its relaxing effects can relieve writer's block. It cannot be considered safe to use during pregnancy as it might cause miscarriages.

While common vervain is not native to North America, it has been introduced there and the Pawnee have adopted it as an entheogen enhancer and in oneiromancy, and is often referred to as the North American version of Calea zacatechichi.

In western Eurasia, the term "verbena" or "vervain" usually refers to this, the most widespread and common member of the mostly American genus occurring there. It was called "tears of Isis" in Ancient Egypt, and later on "Juno's tears". In Ancient Greece, it was dedicated to Eos Erigineia. In the early Christian era, folk legend stated that Common Vervain was used to staunch Jesus' wounds after his removal from the cross; hence names like "Holy Herb" or (e.g. in Wales) "Devil's bane"

Because of the association with the Passion of Christ, it came to be used in ointments to drive out and repel "demonic" illness. Vervain flowers are engraved on cimaruta, Italian anti-stregheria charms. In the 1870 The History and Practice of Magic by "Paul Christian" (Jean-Baptiste Pitois) it is employed in the preparation of a mandragora charm

Hazlitt's Faiths and Folklore (1905) quotes Aubrey's Miscellanies (1721): "Vervain and Dill / Hinder witches from their will."

A Royal Navy Arabis-class sloop of the World War I era was named HMS Verbena, and in World War II a Group 1 Flower-class corvette bore the same name; a Group 2 vessel of the latter class was called HMS Vervain. The only Verbena widely found in England in a native state is common vervain, though it is just as possible that the names reference the popular ornamental verbenas, such as the garden vervain.

9-9-2023 MONTE CORONA, VALENCIA - CRICKET BAT ORBWEAVER (Mangora acalypha)


Mangora acalypha, also known by its common name cricket-bat orbweaver, is a species of spider in the family Araneidae, found throughout the Palearctic realm. This species was originally described by Charles Athanase Walckenaer in 1802 as Aranea acalypha.

Mangora acalypha is common in meadows, forests and gardens.

7-9-2023 MONTE CORONA, VALENCIA - HARVESTMAN SPIDER (Cosmobunus granarius)


 

7-9-2023 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.

This quite common species is present in most of Europe, the Afrotropical realm, eastern Palearctic realm, the Near East, and North Africa, and recently seen 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.

7-9-2023 MONTE CORONA, VALENCIA - BLUE ROCK THRUSH (FEMALE) (Monticola solitarius)

The blue rock thrush (Monticola solitarius) is a species of chat. This thrush-like Old World flycatcher was formerly placed in the family Turdidae. It breeds in southern Europe, northwest Africa, and from Central Asia to northern China and Malaysia. The blue rock thrush is the official national bird of Malta (the word for it in Maltese being Merill) and was shown on the Lm 1 coins that were part of the country's former currency.


29-8-2023 EL SALER, ALBUFERA - BARN SWALLOW (Hirundo rustica)


The barn swallow (Hirundo rustica) is the most widespread species of swallow in the world. It appears to have the largest natural distribution of any of the world's passerines, ranging over 251 million square kilometres globally. It is a distinctive passerine bird with blue upperparts and a long, deeply forked tail. It is found in Europe, Asia, Africa and the Americas. In Anglophone Europe it is just called the swallow; in northern Europe it is the only common species called a "swallow" rather than a "martin".

There are six subspecies of barn swallow, which breed across the Northern Hemisphere. Four are strongly migratory, and their wintering grounds cover much of the Southern Hemisphere as far south as central Argentina, the Cape Province of South Africa, and northern Australia. Its huge range means that the barn swallow is not endangered, although there may be local population declines due to specific threats.

The barn swallow is a bird of open country that normally nests in man-made structures and consequently has spread with human expansion. It builds a cup nest from mud pellets in barns or similar structures and feeds on insects caught in flight. This species lives in close association with humans, and its insect-eating habits mean that it is tolerated by humans; this acceptance was reinforced in the past by superstitions regarding the bird and its nest. There are frequent cultural references to the barn swallow in literary and religious works due to both its living in close proximity to humans and its annual migration. The barn swallow is the national bird of Austria and Estonia.

29-8-2023 RACO DE OLLA, ALBUFERA - LITTLE RINGED PLOVER (Charadrius dubius)


The little ringed plover (Charadrius dubius) is a small plover. The genus name Charadrius is a Late Latin word for a yellowish bird mentioned in the fourth-century Vulgate. It derives from Ancient Greek kharadrios a bird found in river valleys (kharadra, "ravine"). The specific dubius is Latin for doubtful, since Sonnerat, writing in 1776, thought this bird might be just a variant of common ringed plover.

Adult little ringed plovers have a grey-brown back and wings, a white belly and a white breast with one black neckband. They have a brown cap, a white forehead, a black mask around the eyes with white above and a short dark bill. The legs are flesh-coloured and the toes are all webbed.

This species differs from the larger ringed plover in leg colour, the head pattern, and the presence of a clear yellow eye-ring.


 Their breeding habitat is open gravel areas near freshwater, including gravel pits, islands and river edges across the Palearctic including northwestern Africa. They nest on the ground on stones with little or no plant growth. Both males and females take turns incubating the eggs.

They are migratory and winter in Africa. These birds forage for food on muddy areas, usually by sight. They eat insects and worms.

6-9-2023 CATARROJA, ALBUFERA - GREY HERON (Ardea cinerea)


The grey heron (Ardea cinerea) is a long-legged wading bird of the heron family, Ardeidae, native throughout temperate Europe and Asia, and also parts of Africa. It is resident in much of its range, but some populations from the more northern parts migrate southwards in autumn. A bird of wetland areas, it can be seen around lakes, rivers, ponds, marshes and on the sea coast. It feeds mostly on aquatic creatures which it catches after standing stationary beside or in the water, or stalking its prey through the shallows.

Standing up to 1 metre (3 ft 3 in) tall, adults weigh from 1 to 2 kg (2 to 4 lb). They have a white head and neck with a broad black stripe that extends from the eye to the black crest. The body and wings are grey above and the underparts are greyish-white, with some black on the flanks. The long, sharply pointed beak is pinkish-yellow and the legs are brown.

The birds breed colonially in spring in heronries, usually building their nests high in trees. A clutch of usually three to five bluish-green eggs is laid. Both birds incubate the eggs for around 25 days, and then both feed the chicks, which fledge when 7-8 weeks old. Many juveniles do not survive their first winter, but if they do, they can expect to live for about 5 years.

In Ancient Egypt, the deity Bennu was depicted as a heron in New Kingdom artwork. In Ancient Rome, the heron was a bird of divination. Roast heron was once a specially prized dish; when George Neville became Archbishop of York in 1465, 400 herons were served to the guests.

6-9-2023 DEVESES, VALENCIA - EAST IBERIAN PSAMMODROMUS LIZARD (Psammodromus edwarsianus)

The East Iberian sand racer or East Iberian psammodromus (Psammodromus edwarsianus) is a species of lizards in the family Lacertidae. It is found in Spain and France.

This small uncommon lizard, is one of three Psammodromus species of lizards that is found in Spain and France. (Others being P. hispanicus (mainly found in the central peninsular strip) and P. occidentalis (mainly found in the Western peninsular strip)) P. edwarsianus is predominately found on the Eastern side of Spain and Southern France. (The Eastern peninsular, mainly land areas bordering onto the Mediterranean Sea).

Habitat: Scrubland, planted with short grasses and low growing shrub plants, also open meadows with gentle slopes littered with large stones and rocks, that can be used for shelter. This is a very small lizard and life expectancy is no more than around two years.

This lizard is active here in Southern Spain all year round (images below were taken in the month of December). It tends to move in short fast bursts for cover into shrubs or under stones, but will also stay motionless for a while, thus relying on its markings and colouration for stealth mode.

Mating season begins in March till July, 2 to 5 eggs are laid, and buried in the soil. Incubation lasts between 8 to 9 weeks. August to September, can see a second laying of eggs.

These delicate small Lizards mainly prey on various insects and grubs, especially larvae (caterpillars) of lepidoptera (butterflies and moths), also small beetles and their larvae, Spiders and grasshoppers will all be on the lizard’s menu as well.

They become prey themselves to multiple predators, like Sea-Birds, Raptors, Shrikes and Egrets, also, Foxes and the larger lizards will also take the opportunity to prey on this small lizard.

As to date, (16.08. 2022) no official protection laws for this species are yet in place, which I personally find disapointing. 

6-9-2023 ULLAL DE BALDOVI, ALBUFERA - VIOLET DROPWING DRAGONFLY (MALE) (Trithemis annulata)


 Rithemis annulata is a robust medium-sized species with a wingspan of 60 mm (2.4 in). The mature male has a dark red head and a yellow labium with brown central spot. The eyes are red with white spots on the rear edge, and the frons is dark metallic purplish-red. The prothorax is violet with slightly darker longitudinal stripes. The membranous wings have distinctive red veins, the pterostigma is orange-brown and there is a large orange-brown splash at the base of the hind wings. The abdomen is fairly broad and is pinkish-violet, with purple markings on the top of each segment and blackish markings on the terminal three segments. Females are a similar size to males but the thorax is brownish and the abdomen is yellow with dark brown markings. The wings of females lack the red veins of males but have similar orange-brown patches. It is very similar in appearance to the red-veined dropwing (Trithemis arteriosa), but that species has a more slender abdomen and a wedge-shaped black area on either side of the tip of the abdomen.

6-9-2023 ULLAL DE BALDOVI, ALBUFERA - SMALL WHITE BUTTERFLY (Pieris rapae)

Pieris rapae is a small- to medium-sized butterfly species of the whites-and-yellows family Pieridae. It is known in Europe as the small white, in North America as the cabbage white or cabbage butterfly,[note 1] on several continents as the small cabbage white, and in New Zealand as the white butterfly. The butterfly is recognizable by its white color with small black dots on its wings, and it can be distinguished from P. brassicae by its larger size and the black band at the tip of its forewings.

The caterpillar of this species, often referred to as the "imported cabbageworm", is a pest to crucifer crops such as cabbage, kale, bok choy and broccoli. Pieris rapae is widespread in Europe and Asia; it is believed to have originated in the Eastern Mediterranean region of Europe, and to have spread across Eurasia thanks to the diversification of brassicaceous crops and the development of human trade routes. Over the past two centuries, it spread to North Africa, North America, New Zealand, and Australia, as a result of accidental introductions.

Mediterranean species: southern Europe and northern Africa. In France, especially in the south.


 

5-9-2023 MONTE CORONA, VALENCIA - SPINY TOAD (JUVENILE) (Bufo spinosus)


 The spiny toad, spiny common toad, or giant toad (Bufo spinosus) is a species of toad native to the Iberian Peninsula, southern France, extreme northeastern Italy, and North Africa (Morocco, Algeria, and Tunisia). There is an isolated population in Jersey in the Channel Islands. For much of the 20th century, it was considered either a synonym or a subspecies of common toad Bufo bufo, but it is now classified as a separate species.

4-9-2023 POTRIES, VALENCIA - VIOLET DROPWING DRAGONFLY (MALE) (Trithemis annulata)


 Trithemis annulata, known commonly as the violet dropwing, violet-marked darter, purple-blushed darter or plum-coloured dropwing, is a species of dragonfly in the family Libellulidae. It is found in most of Africa, in the Middle East, in the Arabian Peninsula and southern Europe. These insects are called dropwings because of their habit of immediately lowering their wings after landing on a perch. Males of this species are violet-red with red veins in the wings while females are yellow and brown. Both sexes have red eyes.

4-9-2023 POTRIES, VALENCIA - HOVERFLY (Ceriana vespiformis)

Ceriana vespiformis is a species of hoverfly. It is a typical wasp mimic, is 10–11 mm long, and has very long antennae for a hoverfly.

C. vespiformis has been reported in mature oak forest and from Mediterranean scrub, where adults visit flowers to feed on nectar. Larvae are found in white mulberry (Morus alba) sap. Adult are seen in Southern Europe from late May to September.

This species' range is mainly Mediterranean (Southern Europe and North Africa). Specimens have been found in Spain, Portugal, France, Italy, Albania, Croatia, Greece, Romania, Turkey, Lebanon, Israel and parts of North Africa. Two specimens have been found in the Netherlands.

4-9-2023 ADOR, VALENCIA - EURASIAN KESTREL (Falco tinnunculus)

The common kestrel (Falco tinnunculus) is a bird of prey species belonging to the kestrel group of the falcon family Falconidae. It is also known as the European kestrel, Eurasian kestrel, or Old World kestrel. In the United Kingdom, where no other kestrel species commonly occurs, it is generally just called "kestrel".

This species occurs over a large range. It is widespread in Europe, Asia, and Africa, as well as occasionally reaching the east coast of North America. It has colonized a few oceanic islands, but vagrant individuals are generally rare; in the whole of Micronesia for example, the species was only recorded twice each on Guam and Saipan in the Marianas.

3-9-2023 MONTE CORONA, VALENCIA - MEDITERRANEAN MANTIS (ADULT) (Iris oratoria)

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

In Germany, M. religiosa is listed as Gefährdet [endangered] on the German Red List on the basis of an assessment from 1998. It is not supposed to be caught or held as a pet. At a global level, it is assessed by the IUCN as least concern.

2-9-2023 MONTE CORONA, VALENCIA - MEDITERRANEAN MANTIS (FEMALE) (Iris oratoria)

Iris oratoria, known by the common name Mediterranean mantis (or less frequently iris mantis), due to humans first studying it in lands around the Mediterranean Sea, is a species of praying mantis. Its range is expanding in the Middle East, Western Asia and the United States.

The Mediterranean mantis is known for two distinctive behaviours, apart from the ambush hunting common to other mantids: cannibalism and deimatic or threat displays. The sexual cannibalism of mantids known in popular culture occurs in roughly one quarter of all intersexual encounters of I. oratoria.

When the mantis is under attack, it sets in motion a complex series of actions which combine to form a startling deimatic display. The mantis turns to face the aggressor, rears up by arching its back, curls its abdomen upwards (dorsiflexion), raises and waves its forelimbs, raises its wings to displays the large brightly coloured eyespots on the hindwings, and stridulates by scraping the edge of its hindwings against its tegmina, the leathery front wings.


2-9-2023 MONTE CORONA, VALENCIA - LARGE PSAMMODROMUS LIZARD (JUVENILE) (Psammodromus algirus)

Psammodromus algirus, known commonly as the Algerian psammodromus or the large psammodromus, is a species of lizard in the family Lacertidae. The species is found in southwestern Europe and northwestern Africa.

Psammodromus algirus is found in North Africa (Morocco, Algeria, and Tunisia) and in Southwestern Europe (Iberian Peninsula: Portugal, Spain, Andorra, Gibraltar; southernmost France, and Italy near Lampedusa).

The IUCN assessment from 2009 treats Psammodromus algirus nollii and Psammodromus algirus ketamensis as full species and restricts Psammodromus algirus to North Africa.

P. algirus typically occurs in dense bushy vegetation, but it can also venture to more open areas. It can be found at at elevations up to 2,600 m (8,500 ft) above sea level, but it is more common at lower elevations.

Psammodromus algirus mainly feeds on terrestrial arthropods, specifically Orthoptera, Formicidae, Coleoptera, Hemiptera, and Araneae.

1-9-2023 MONTE CORONA, VALENCIA - SOUTHERN GREEN STINK BUG (Nezara viridula)

Nezara viridula, commonly known as the southern green stink bug (USA), southern green shield bug (UK) or green vegetable bug (Australia and New Zealand), is a plant-feeding stink bug. Believed to have originated in Ethiopia, it can now be found around the world.[1] Because of its preference for certain species of legumes, such as beans and soybeans, it is an economically important pest on such crops.

The adult males can reach a body length (from front to elytral apex) of about 12.1 millimetres (0.48 in), while females are bigger, reaching a size of about 13.1 millimetres (0.52 in). The body is usually bright green and shield-shaped and the eyes are usually reddish, but they may also be black. There is a row of three white spots on the scutellum. They differ from the similar green stink bug (Chinavia hilare) by the shape of their scent gland openings, which are short and wide in N. viridula, and narrow and long in the green stink bug.

Nezara viridula reproduces throughout the year in tropics. In temperate zones this species presents a reproductive winter diapause, associated with a reversible change of body colouration from green to brown or russet.

When ready to mate N.viridula sound 100 Hz vibration with a "tymbal" composed of a fused first and second terga (not to be confused with tymbal of cicadas) that allow bi-directional communication to any Nezara standing on the same plant so they could find each other. The female lays 30 to 130 eggs at a time, in the form of an egg mass glued firmly to the bottom of a leaf. The eggs are barrel-shaped, with an opening on the top. The eggs take between 5 and 21 days to develop, depending on the temperature. The newborn larvae gather near the empty eggs and do not feed until three days later, after the first moult. They moult five times before reaching maturity, increasing in size each time. Each instar stage lasts about a week, except for the last one before the metamorphosis, which is a day longer. Up to four generations can develop in one year, with eggs developing into adults in as few as 35 days in mid-summer. Up until their third moult the larvae aggregate together on the host plant, the purpose of this aggregation is probably pooling of chemical defenses against predators, for example ants.


 

1-9-2023 MONTE CORONA, VALENCIA - SCHILLING'S ROPALID

In contrast to other rhopalids, Chorosoma schillingi and Myrmus miriformis are rather hairless as adults and elongate in shape. This species in particular is very long and narrow, leading to possible confusion with some mirid grass bugs. Note however the membranous wings and ocelli.

A straw-coloured species with very long legs and antennae, C. schillingi is superbly camouflaged as it walks slowly amongst grasses. It is usually brachypterous, the wings reaching half the length of the adomen.

This species has a southerly and mainly coastal distribution, and is found locally in dunes and tall grasslands between Norfolk and Anglesey, feeding on various grasses including marram.

Adult August-September

Length 14-16 mm
