29-5-2020 GANDIA MARJAL, VALENCIA - SPOTTED FLYCATCHER (Muscicapa striata)

Spotted flycatchers are one of our summer migrants that spend the winter in Africa. They are one of the latest migrants to reach us, with a few trickling into the country from late April and most arriving from mid-May.

Despite arriving relatively late, spotted flycatchers manage to rear two broods of young before departing at the end of August. The success of the second clutch is increased by fewer eggs being laid, meaning less mouths to fill. They will nest in gardens but the nest is usually well hidden on ledges or behind climbing plants.

Spotted flycatchers prefer large flying insects, including flies and butterflies. However, if the weather is cool and insects aren’t flying, they will take smaller invertebrates from leaves and branches. If poor weather persists, many nests fail as these smaller invertebrates tend to be eaten by the parents rather than fed to the young.

In order to reduce the chances of their invertebrate prey escaping, spotted flycatchers have a series of modified feathers, like bristles, down the sides of the bill. They have also adapted to catch stinging insects. They rub the sting end on their perch to remove it, making the prey safe to eat.

The spotted flycatcher is red listed due to its rapid and consistent population decline with an 89 per cent decrease between 1967 and 2012. Evidence suggests that this is due to poor annual survival rates of first year birds, but conditions in their wintering grounds in Africa may also have contributed to the decline.

29-5-2020 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.

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.

29-5-2020 GANDIA MARJAL, VALENCIA - GREYLAG GOOSE (Anser anser)

The Greylag Goose (Anser anser) is a large and robust member of the waterfowl family Anatidae, easily recognized by its mottled and barred grey and white plumage. It boasts an orange beak, pink legs, and a sizeable stature, measuring between 74 and 91 centimeters in length and weighing an average of 3.3 kilograms. This species is the progenitor of most domestic goose breeds and exhibits a wide distribution across Europe and Asia.

Adult Greylag Geese have a rotund body, a thick and long neck, and a large head and bill. Their legs and feet are pink, and their bill is orange or pink with a white or brown nail. The wingspan ranges from 147 to 180 centimeters. Males are typically larger than females, and the eastern subspecies rubirostris is larger than the nominate subspecies. The plumage is greyish brown with a darker head and paler underparts, with black spotting that varies among individuals. Juveniles can be identified by their lack of black speckling and greyish legs.

29-5-2020 GANDIA MARJAL, VALENCIA - EURASIAN COOT (Fulica atra)

The Eurasian coot, Fulica atra, also known as the common coot or Australian coot, is a distinctive waterbird with a slaty-black body, a glossy black head, and a striking white bill topped with a white frontal shield. This bird is a member of the Rallidae family, which includes rails and crakes. Both sexes exhibit similar plumage, making them indistinguishable in the field.

Adult Eurasian coots measure 36–38 cm in length with a wingspan of 70–80 cm. Males are slightly heavier than females, weighing around 890 g compared to the females' 750 g. The species is characterized by its white bill and frontal shield, which contrast sharply with its all-black body. Juveniles are paler with a whitish breast and lack the facial shield, which develops fully by one year of age.

The Eurasian coot is found on freshwater lakes and ponds and has adapted well to urban environments, often seen in city parks and gardens with water bodies.

This bird has a broad range across the Old World, including Europe, Asia, Australia, New Zealand, and parts of North Africa. It is a resident in milder regions but migrates south and west from much of Asia during winter.

The Eurasian coot is less secretive than many rails, often visible on open water or grasslands. It is territorial and aggressive during the breeding season, with both parents defending their territory. In non-breeding seasons, coots may form large flocks. They are reluctant flyers, preferring to run across water surfaces, and are known for bobbing their heads while swimming.

29-5-2020 GANDIA PLAYA, VALENCIA - SAND STOCK (Malcolmia littorea)

Sand Stock (Malcolmia littorea) is a hardy perennial shrublet of the cabbage family (Brassicaceae). It is famous for its vibrant, star-shaped purple-pink flowers and can be found native to the coastal sand dunes and rocky shores of the western Mediterranean and Atlantic coasts (including Spain, Portugal, France, and North Africa).

Key Facts at a Glance

Physical Characteristics: Stems grow about 10-40 cm long. Its woody base is covered in ash-white hairs (trichomes). Leaves are elliptical, sometimes dentate, and lean on the stalks.

Flowers: Displays blooms with 4 heart-shaped petals (ranging from lilac-pink to bright purple) and distinct stamens. They give off an amazing, sweet scent.

Habitat: Endemic to harsh, dry, and salty coastal dunes. It plays an important role in fixing sand and stabilizing coastal ecosystems.

Blooming Season: Primarily flowers in spring (February to May), though in some western areas it can bloom through early summer.

Conservation Status: Thrives in hardiness zones 7 to 10. However, due to coastal development and habitat loss, it is considered endangered and highly protected in several areas, such as the dunes of Galicia.

29-5-2020 GANDIA MARJAL, VALENCIA - EUROPEAN SERIN (MALE) (Serinus serinus)

The European serin, or simply the serin (Serinus serinus), is a diminutive member of the finch family, Fringillidae. This sprightly bird is the smallest within its family, closely related to the Atlantic canary. It is characterized by its short tail and a length that spans a mere 11 to 12 centimeters. The serin's plumage is a tapestry of nature's palette, with upper parts dappled in dark-streaked greyish green and a conspicuous yellow rump. The underparts are a canvas of yellow breast and white belly, both adorned with heavy streaks.

When attempting to identify the European serin, look for the male's radiant yellow face and breast, which stand out against the greenish backdrop of its feathers. The male also boasts yellow wing bars and yellow tail sides, which can be quite helpful in distinguishing it from similar species. Both sexes share a buzzing trill of a song that resonates through their Mediterranean habitats.

The European serin is partial to open woodland and cultivated areas, often with a sprinkling of conifers. These environments provide the perfect backdrop for breeding and foraging.

This species has a breeding range that extends across southern and central Europe and into North Africa. Populations along the southern and Atlantic coasts tend to be resident, while those in the north are migratory, seeking warmer climates in southern Europe during the winter months.

29-5-2020 GANDIA MARJAL, VALENCIA - YELLOW IRIS (Iris pseudacorus)

Iris pseudacorus (yellow flag iris) is a bright yellow, semi-aquatic perennial plant. Though often used in water gardens for its beauty, it is a highly invasive species, especially in North America, that spreads rapidly via rhizomes and seeds to crowd out native vegetation. It thrives in wetlands, pond edges, and wet soils.

Key Facts About Yellow Iris (Iris pseudacorus):

Invasive Nature: Listed as a high-risk invasive species and noxious weed in many areas, as it forms dense mats and ruins wetlands.

Identification: Features bright yellow flowers, often with purple-brown veining on the petals, that bloom from April to July. The leaves are long, flat, and sword-like.

Habitat: Commonly found in wetlands, fens, coastal areas, marshes, and along banks of rivers and streams.

Highly Toxic: The roots and leaves are poisonous, causing skin irritation, blistering, and severe illness if consumed by humans or livestock.

Reproduction: Spreads through seeds (which can float on water) and hardy rhizomes.

Uses: Used as an ornamental plant in gardens but often escapes into the wild. It is also used to filter nutrients like phosphorus and nitrogen out of water in specialized water treatment systems.

Removal Advice: Due to the risk of leaving behind root fragments that can regrow, manual removal can be difficult and should be done with care, ensuring the plant is not composted but sent to a landfill.

Background and Ecological ImpactOrigin: Native to Europe, North Africa, and Asia.

Appearance: They can grow up to 2-6 feet tall. The seed pods are large, green, and turn brown, containing many seeds that can float for extended periods to establish new colonies.

Wildlife Impact: Yellow iris can quickly become a monoculture, reducing biodiversity in wetlands, as noted in the Yellow Flag Iris (Iris pseudacorus)

29-5-2020 GANDIA MARJAL, VALENCIA - BEAR'S BREECHES (Acanthus mollis)

Acanthus mollis, commonly known as bear's breeches, sea dock, bear's foot plant, sea holly, gator plant or oyster plant, is a species of plant in the family Acanthaceae and is native to the Mediterranean region. It is a leafy, clump-forming perennial herb, with a rosette of relatively large, lobed or toothed leaves, and purplish and white flowers on an erect spike.

Acanthus mollis is a leafy, clump-forming perennial herb with tuberous roots. It has a basal rosette of dark glossy green, lobed or divided, glabrous leaves 50 cm (20 in) long and 30 cm (12 in) wide on a petiole 20–30 cm (7.9–11.8 in) long. The flowers are borne on an erect spike up to 200 cm (79 in) tall emerging from the leaf rosette. The sepals are purplish and function as the upper and lower lips of the petals, the upper lip about 4 cm (1.6 in) long and the lower lip 3 cm (1.2 in) long. The petals are about 4–4.5 cm (1.6–1.8 in) long and form a tube with a ring of hairs where the stamens are attached. Flowering occurs in summer and the fruit is a sharply-pointed capsule about 2 cm (0.79 in) long containing one or two brown seeds about 14 mm (0.55 in) long and 8 mm (0.31 in) wide.

Although native to the eastern and central Mediterranean, Acanthus mollis has spread throughout much of western Europe and certain parts of the Americas, Australia, Syria[ and New Zealand, where it is regarded as invasive.

Acanthus mollis is entomophilous, pollinated only by bees or bumble bees large enough to force their way between the upper sepal and the lower, so that they can reach the nectar at the bottom of the tube.

29-5-2020 MONTE CORONA, VALENCIA - BURNET MOTH (Zygaena lavandulae)

Zygaena lavandulae is a species of moth in the family Zygaenidae.

This species can be found in Southern France, eastern Spain, Portugal and Italy (only in central and western Liguria), as well as North Africa, including Morocco.

Zygaena lavandulae has a wingspan of 31–36 millimetres (1.2–1.4 in) in males and of 35–37 millimetres (1.4–1.5 in) in females. The head is black. The thorax is black with a white collar. Also the abdomen is black, with a slight blue gloss. Forewings are bluish, with five red spots surrounded with black or dark blue. Hindwings are bluish-black with a very large distal red spot. Colorations of the females are rather similar to males, but their forewings are usually bluish-green, with larger spots.

These moths mainly inhabit rocky places, dry woods and grove rich grasslands. They are present in the Maquis shrubland, characterized by the widespread presence of Cistus species.

There is one generation per year (univoltine). The larvae feed on Dorycnium pentaphyllum and Anthyllis cytisoides. They develop until April without real dormancy. Adults are on wing from April to June.

28-5-2020 VILLALONGA RESERVOIR, VALENCIA - SPOTTED FLYCATCHER (Muscicapa striata)

Spotted flycatchers are one of our summer migrants that spend the winter in Africa. They are one of the latest migrants to reach us, with a few trickling into the country from late April and most arriving from mid-May.

The spotted flycatcher is red listed due to its rapid and consistent population decline with an 89 per cent decrease between 1967 and 2012. Evidence suggests that this is due to poor annual survival rates of first year birds, but conditions in their wintering grounds in Africa may also have contributed to the decline.

Spotted flycatchers are fairly drab birds, with brown-grey upperparts. Below they have dull white plumage with pale streaking, and there is streaking on the head. Juveniles are similar but have pale spots on their upperparts. Despite their dull appearance, they are easy to spot as they like to perch on exposed posts or branches from which they catch their prey.

As well as looking plain, the spotted flycatcher’s song is pretty unremarkable. It is squeaky, mostly unmelodic and very soft. The squeaky part of the song is part of its territorial defence, and the more musical sequences are aimed at potential mates.

28-5-2020 VILLALONGA RESERVOIR, VALENCIA - SMALL PINCERTAIL DRAGONFLY (Onychogomphus forcipatus)

Onychogomphus forcipatus, the small pincertail, green-eyed hooktail, or green-eyed hook-tailed dragonfly, is a species of dragonfly belonging to the family Gomphidae.

This quite common and widespread dragonfly is present in most of Europe, in North Africa (Algeria, Morocco, Tunisia), and in West/Central Asia (Armenia, Azerbaijan, Iran, Kazakhstan, and Turkmenistan).

These dragonflies usually inhabit clean rivers with a little faster running water and gravel or sandy banks. Occasionally they are also present at large lakes.

The adults of Onychogomphus forcipatus grow up to 6 centimetres (2.4 in) long, with a wingspan of 5.5–7.5 centimetres (2.2–3.0 in). The eyes of these medium-sized dragonflies are widely separated and grey-to-green. The two black lines on the side of the thorax are relatively narrow and touch the midline. It has a yellow line on the vertex and two cells above the anal triangle. The abdomen in males is fitted with three hooks of large size (anal appendages). Cercoids may be dark and have a subterminal tooth. The base of the hindwing is angled in males and rounded in females.

This species is rather similar to Onychogomphus uncatus. The two species can be distinguished on the basis of the shape and extension of the black markings, especially on the thorax and on the last abdominal segments.

Adults can be encountered close to running water and lakes from June through September. In Southern Europe, the emergence period typically begins in April. In Cyprus, the flight season of the subspecies O. f. albotibialis is from late March to October. This subspecies is classified as a Near-threatened species. After the mating the females lay about 500 eggs into the water. Larvae dig and live buried in the bottom. Their life cycle from egg to imago lasts about 3–5 years.

Appearance & Identification

Eyes: Separated, typically grey to green in color.

Body: A base yellow color overlaid with black markings. The black lines on the side of the thorax are thin and wavy.

Appendages: Males feature prominent, curved anal appendages resembling sugar tongs, which give the species its common name.

Lookalikes: It is easily confused with the Large Pincertail (Onychogomphus uncatus), which generally has bright blue eyes and thicker black markings on the thorax.

28-5-2020 VILLALONGA RESERVOIR, VALENCIA - EPAULET SKIMMER DRAGONFLY (MALE AND FEMALE MATING) (Orthetrum chrysostigma)

Orthetrum chrysostigma, the epaulet skimmer, is a species of dragonfly in the family Libellulidae. It is found in Algeria, Angola, Benin, Botswana, Burkina Faso, Cameroon, Central African Republic, Chad, the Democratic Republic of the Congo, Ivory Coast, Egypt, Equatorial Guinea, Ethiopia, Gambia, Ghana, Guinea, Israel, Kenya, Liberia, Libya, Malawi, Mali, Mauritania, Morocco, Mozambique, Namibia, Niger, Nigeria, Senegal, Sierra Leone, Somalia, South Africa, Sudan, Tanzania, Togo, Uganda, Zambia, Zimbabwe, and possibly Burundi as well as Canary Islands, and Portugal. It was recorded in the Maltese Islands in 2010.

Its natural habitats are subtropical or tropical moist lowland forests, dry savanna, moist savanna, subtropical or tropical dry shrubland, subtropical or tropical moist shrubland, rivers, intermittent rivers, shrub-dominated wetlands, swamps, freshwater lakes, intermittent freshwater lakes, freshwater marshes, intermittent freshwater marshes, and freshwater springs. The adults prey on various flying insects. The bodies of adult males are blue, and those of young and females are yellow and brown.

28-5-2020 VILLALONGA RESERVOIR, VALENCIA - COPPER DEMOISELLE DAMSELFLY (MALE) (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.

27-5-2020 MONTE CORONA, VALENCIA - FUNNEL WEAVER SPIDER (Lycosoides coarctata)

Textrix is a genus of funnel weavers first described by Carl Jakob Sundevall in 1833. They have a mainly European distribution, with one species in Ethiopia. The type species of the genus is Textrix denticulata.

The spiders in the genus Textrix have a strongly recurved posterior row of eyes with the medial eyes larger than the lateral eyes. They have a narrow head which is distinct from the thorax. These spiders may resemble wolf spiders as they are often recorded running about in sunshine, but their long and segmented posterior spinners are very marked and identify them as funnel web weavers.

As of August 2023 it contains six species:

Textrix caudata L. Koch, 1872 – Macaronesia, Northern Africa, Southern Europe, Syria

Textrix chyzeri de Blauwe, 1980 – Hungary, Croatia, Bosnia and Herzegovina, Montenegro, Bulgaria

Textrix denticulata (Olivier, 1789) (type) – Europe, Turkey

Textrix nigromarginata Strand, 1906 – Ethiopia

Textrix pinicola Simon, 1875 – Portugal to Italy

Textrix rubrofoliata Pesarini, 1990 – Spain, France, Italy

27-5-2020 MONTE CORONA, 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.

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.

27-5-2020 MONTE CORONA, VALENCIA - FLUFFY HACKLED ORBWEB SPIDER (Uloborus walckenaerius)

Uloborus walckenaerius, also known as the feather-legged spider, is a cribellate spider in the family Uloboridae. Like all spiders in this family, they do not have venom glands and immobilize their prey with over 140 m of thread. They are named in honor of Charles Athanase Walckenaer.

It is commonly known as the fluffy hackled orb-web spider.

Adult females have a body length of 3.5–6 mm (0.14–0.24 in), males 3–4 mm (0.12–0.17 in). They have a dark grey prosoma, covered with white hairs, leaving some dark bands uncovered. They have eight eyes, arranged in two almost parallel rows of four, with the anterior lateral eyes on the front corners of the head. The abdomen is greyish-white in colour, with a continuation of the pattern on the carapace. It bears a brown median line, with alternating white and brown bands on either side. There are fluffy white tufts of hair on the white bands, which are very distinct from the side. The legs range from dark grey-brown to reddish-brown, with faint, white annulations. The front two pairs of legs are significantly longer than the rear pairs.

Uloborus walckenaerius has a widespread distribution throughout the Palearctic region and has been introduced to Cape Verde, Saint Helena, and South Africa.

The spider lives in warm, open terrain, like heathland, and weaves horizontal cribellate orb webs close to the ground. A stabilimentum is sometimes present, and the spider hangs beneath the hub.

27-5-2020 MONTE CORONA, VALENCIA - CONEHEAD MANTIS (Empusa pennata)

Empusa pennata, or the conehead mantis, is a species of praying mantis in genus Empusa native to the Mediterranean Region. It can be found in Portugal, Spain, southern France, Italy and on the mediterranean coasts of Morocco, Algeria, Tunisia, Libya, Turkey and Egypt. Because of its cryptic nature, or also possibly because of its fragmented, low-density populations, it is rarely encountered in the wild.

Empusa pennata generally has a large, thin body with a low mass, as well as a large pair of wings used for flight. They are mostly found in perennial herbs and scrubs. There are three ways for these insects to find mates: chemical, acoustic, and visual signals. Some predatory insects like mantises rely on cryptic colouration; they use this camouflage to protect themselves from predators and capture prey.

This species of mantis, although similar in size to the common European mantis (Mantis religiosa), is easily distinguished by the protrusion from its crown. Both males and females possess this tall extension from birth, giving them a very 'alien' appearance.

They live in dry, warm environments and use their cryptic colouring of either greens and pinks or various shades of brown to keep hidden from predators. Females may grow to a length of 10 cm, while males are shorter and slimmer. Males have distinctive ‘feather’-type antennae. Empusa pennata overwinters as a nymph and reaches the adult stage by spring. Its eggs develop quickly, especially in the summer months.

25-5-2020 MONTE CORONA, VALENCIA - SPECKLED WOOD BUTTERFLY (Pararge aegeria)

The speckled wood (Pararge aegeria) is a butterfly found in and on the borders of woodland areas throughout much of the Palearctic realm. The species is subdivided into multiple subspecies, including Pararge aegeria aegeria, Pararge aegeria tircis, Pararge aegeria oblita, and Pararge aegeria insula. The color of this butterfly varies between subspecies. The existence of these subspecies is due to variation in morphology down a gradient corresponding to a geographic cline. 

The background of the wings ranges from brown to orange, and the spots are either pale yellow, white, cream, or a tawny orange. The speckled wood feeds on a variety of grass species. The males of this species exhibit two types of mate locating behaviors: territorial defense and patrolling. The proportion of males exhibiting these two strategies changes based on ecological conditions. The monandrous female must choose which type of male can help her reproduce successfully. Her decision is heavily influenced by environmental conditions.

26-5-2020 MONTE CORONA, VALENCIA - JUNE BEETLE (Anoxia australis)

Melolonthinae is a subfamily of the scarab beetles (family Scarabaeidae). It is a very diverse group; distributed over most of the world, it contains over 11,000 species in over 750 genera. Some authors include the scarab subfamilies Euchirinae and Pachypodinae as tribes in the Melolonthinae.

Unlike some of their relatives, their habitus is usually not bizarre. They resemble the Rutelinae in being fairly plesiomorphic in outward appearance. Like in many Scarabaeidae, males have large fingered antennae, while those of the females are smaller and somewhat knobby. In the Melolonthinae, this sexual dimorphism is particularly pronounced. Many species have striking – though rarely brilliant or iridescent – hues and bold patterns of hairs.

Being often quite sizeable and swarming in numbers at certain times, for example the Amphimallon, Phyllophaga and Polyphylla "June beetles" or the Melolontha cockchafers – all from tribe Melolonthini – feature widely in folklore. Some Melolonthinae are economically significant pests. Other than the Melolonthini, the most diverse tribes are the Ablaberini, Liparetrini, Macrodactylini, Tanyproctini and Sericini.

Melolonthinae adults range from 3 to 58 mm in length and are usually brown or black in colour. Some species are shiny, while many are covered in setae or scales. The clypeus, a structure on the head above the mouthparts, is not armed with teeth. There are two antennae, each with 7 to 10 segments, of which the last 3 to 7 segments are elongate and form a club, and the antennal bases are usually concealed from above. The scutellum is exposed at the base of the elytra. The margins of the elytra are straight instead of strongly curved. Each leg ends in a pair of tarsal claws that are often toothed or double.

Larvae are C-shaped with a white/cream body and a darker, well-sclerotised head. They can be distinguished from other scarabaeid larvae by the galea and lacinia either partly fused proximally or fitting tightly together, the mandibles lacking stridulatory areas, the apical segment of the antenna about as wide as its penultimate segment, and the anal cleft usually Y-shaped or angulate.

The Melolonthinae life cycle has the four stages of egg, larva, pupa and adult, similar to other beetles. Eggs are laid in soil, which is also where the larval and pupal stages occur. Adults occur above ground. The larval stage is long and may last up to two years, whereas the adult stage is short and lasts only a few days or weeks.

Larval melolonthines feed on plant roots and humus. Known host plants include grasses, clover and sugarcane. Adults may (e.g. Automolius, Diphucephala, Heteronyx, Liparetrus, Phyllotocus and Sericesthis) or may not feed (e.g. Antitrogus and Rhopaea). Adults that feed do so on the leaves of trees, such as eucalypts, or on flowers or pollen.

Adults are usually crepuscular or nocturnal, but the flower- and pollen-feeding species are often diurnal. They are often attracted to light.

In feeding species, adults gather on trees and this helps them find each other to mate. In non-feeding species, virgin females emit a sex pheromone so that males can find them.

Larvae of Sericesthis spp. are pasture pests, while larvae of Dermolepida albohirtum, Antitrogus and Lepidiota are sugarcane pests. Lepidiota stigma is another sugarcane pest and also attacks corn, sorghum and various fruits. Adults of Phyllophaga spp. can sometimes cause complete defoliation of deciduous trees.

25-5-2020 VILLALONGA TUNNELS, VALENCIA - IBERIAN GREEN FROG (Pelophylax perezi)

The Perez's frog (Pelophylax perezi), also known as Iberian waterfrog, Iberian green frog or Coruna frog, is a species of frog in the family Ranidae. It is native to southern France, Portugal, Spain, and has been introduced to the Canary and Balearic Islands, Madeira, the United Kingdom, and the Azores. In the Iberian Peninsula it is widespread and common.

Its natural habitats are temperate forests, temperate shrubland, Mediterranean-type shrubby vegetation, rivers, intermittent rivers, swamps, freshwater lakes, intermittent freshwater lakes, freshwater marshes, intermittent freshwater marshes, sandy shores, arable land, and urban areas. It is not considered threatened by the IUCN. A medium-sized, stout frog; snout-vent length is usually from 40 to 70 mm, but sometimes is longer than 10 cm (Docampo and Milagrosa-Vega 1988; González de la Vega 1988). The head is as long as wide, with prominent eyes located in dorsal position very close to each other. The tympanum is well marked, about 1/2 to 3/4 the eye diameter (Salvador and García-París 2001). Toes have well developed webbing. Skin is either smooth or slightly rough, with well-formed dorsolateral folds.

25-5-2020 VILLALONGA TUNNELS, VALENCIA - GIANT WATER SCAVENGER BEETLE (Genus Hydrophilus)

Giant water scavenger beetles (genus Hydrophilus) are among the largest aquatic beetles, with some adults reaching up to 50 mm (2 inches) in length. They are completely aquatic in their adult stage, using specialized fringed hind legs to row through stagnant freshwater, and they are also strong flyers that migrate between ponds.

Habitat & Diet: They inhabit stagnant ponds and marshes. Adults are scavengers that primarily consume decaying organic matter and algae, while the larvae are voracious predators that hunt small invertebrates like snails and mosquito larvae.

Breathing Technique: Unlike other water insects, they hang suspended from the surface headfirst. They extend their antennae to break the surface film and trap a fresh bubble of air against their fuzzy underbelly, which looks like a silvery coating underwater.

Life Cycle & Eggs: Females lay up to 140 eggs in a waterproof, silken cocoon that typically features a protruding "mast" for ventilation. This cocoon is either attached to underwater vegetation, floated on the water surface, or carried by the female.

25-5-2020 MONTE CORONA, VALENCIA - GREAT TIT (Parus major)

The great tit (Parus major) is a small passerine bird, easily recognized by its black head and neck, striking white cheeks, olive upperparts, and vibrant yellow underparts. This bird is the most widespread species in the genus Parus, found across Europe, the Middle East, Central Asia, and parts of North Africa.

Males are characterized by their bright plumage, with a black bib that extends down the belly, bordered by a lemon-yellow breast. Females and juveniles are similar but have duller coloration. The black line down the belly is also narrower and sometimes broken in these birds.

Great tits favor a variety of woodland habitats, including deciduous and mixed forests, forest edges, and even urban parks and gardens. They are also found in riverine woodlands and, in some regions, boreal taiga.

This species is resident throughout its range, which extends from the Iberian Peninsula to the Amur Valley, and from Scandinavia to the Middle East. It is generally non-migratory, except in harsh winters when it may move to more temperate areas.

Great tits are known for their intelligence and adaptability. They exhibit a range of foraging behaviors and can solve problems with insight learning. They are also cavity nesters and are monogamous, with both parents involved in raising the chicks.

The great tit has a repertoire of up to 40 calls and songs, with the male being particularly vocal. A common call resembles the phrase "teacher, teacher," which is used to proclaim territory.

Breeding occurs once a year, with the female laying up to 12 eggs in a cavity nest. The female incubates the eggs alone, but both parents feed the chicks. In most years, the pair will raise two broods.

The great tit can be confused with other members of the Parus genus, but its distinctive coloration and song usually make it easy to identify.

In summer, the diet is predominantly insectivorous, while in winter, it expands to include seeds and berries. Great tits are adept at handling large food items and are known to visit bird feeders in urban areas.

The great tit is classified as Least Concern by the IUCN, with a stable and widespread population estimated to be between 300 and 1,100 million birds. It has adapted well to human changes in the environment and is not currently at risk.

25-5-2020 VILLALONGA TUNNELS, VALENCIA - SISAL (Agave sisalana)

Agave sisalana, commonly known as sisal, is an evergreen succulent native to Mexico. Renowned for its stiff, durable fibers used in rope, twine, and textiles, the plant thrives in tropical and subtropical climates, boasting a lifespan of 7 to 10 years before flowering and dying. 

Plant Anatomy & Growth

Appearance: Features a dense rosette of stiff, sword-shaped leaves that grow up to 1.5 to 2 meters tall. The leaf edges are smooth or have very minute teeth, ending in a prominent, sharp terminal spine.

Lifespan: The plant lives for 7 to 10 years, producing about 200 to 250 commercially viable leaves.

Lifecycle: It blooms only once in its lifetime, sending up a massive 5 to 6-meter flowering stalk (inflorescence) with yellowish-green flowers. The plant dies after flowering, but regenerates via basal suckers and small bulbils on the stalk.
