Ranitas Pitadoras

Evidentemente, sigo sin poder hacer fotos de insectos.

Llueve a diario aquí en Montalbán.

Los jardínes se llenan de ranas, algo que no sucedió el año pasado.

Saludos.

Aún sin tiempo para clasificar insectos...

Pero sigo encontrando ranas...

Estoy sin tiempo para clasificar insectos...

Ciertamente estoy sin tiempo para dedicarme a la clasificación de insectos (mis favoritos). De hecho, estoy sin tiempo de tomar tantas fotos como quisiera.

Por los momentos, esta rana que apareció en los muebles de mi casa... :(

Saludos,

Dryas iulia Fabricius, 1775.

Kingdom: Animalia
Phylum: Arthropoda
Class: Insecta
Order: Lepidoptera
Family: Nymphalidae
Subfamily: Heliconiinae
Tribe: Heliconiini
Subtribe: Heliconiiti
Genus: Dryas -- Hübner, 1807
Species: D. iulia
Binomial name: Dryas iulia --(Fabricius, 1775)


Identification: Dryas iulia (incorrectly spelled julia), commonly called the Julia Butterfly or Julia Heliconian, is a species of brush-footed butterfly. The sole representative of its genus Dryas, it is native from Brazil to southern Texas and Florida, and in summer can sometimes be found as far north as eastern Nebraska. Over 15 subspecies have been described.

Wings colored orange (brighter in male specimens) with black markings; this species is somewhat unpalatable to birds and belongs to the "orange" Batesian mimic complex

Life history: This butterfly is a fast flier and frequents clearings, paths, and margins of forests and woodlands. It feeds on the nectar of flowers, such as lantanas (Lantana) and Shepherd's-needle (Scandix pecten-veneris). Its caterpillars feeds on leaves of passion vines including Passiflora affinis and Yellow Passionflower (P. lutea) in Texas.

Flight: All year in tropical habitats.

Wing span: Ranges from 82 to 92 mm

Heliconius erato hydara - Hewitson, 1867(Crimson-patched Longwing)

Phylum: Arthropoda - Arthropods
Class: Insecta - Insects
Order: Lepidoptera - Butterflies and Moths
Superfamily: Papilionoidea - Butterflies (excluding skippers)
Family: Nymphalidae - Brushfooted Butterflies
Subfamily: Heliconiinae - Heliconians and Fritillaries
Genus: Heliconius
Species: erato
Sub Species: hydara

Introduction:
This widespread, geographically variable butterfly (see map 2 below) is involved in Müllerian mimicry with the concordantly variable Heliconius melpomene over most of its range. Only H. erato chestertonii Hewitson does not have a corresponding H. melpomene co-mimic. That race, from the upper Cauca valley of Colombia, is a co-mimic of H. cydno weymeri Staudinger.

Etymology: ERATO was one of the nine Muses, the goddesses of music, song and dance. Her name means "the lovely" or "beloved" from the Greek word eratos. In Classical times, when the Muses were assigned specific artistic spheres, she was named Muse of erotic poetry and mimic imitation and represented holding a lyre (ERATO).

Characteristics:
Early stages: Eggs are yellow and approximately 1.5 x 0.9 mm (h x w). Females usually place eggs singly on growing shoots of the host plant. Mature larvae have a white body with black and orange spots, black scoli, and yellow head; length is around 1.3 cm. Caterpillars are solitary (Brown, 1981). Pupae are brown with gold spots on the dorsum, the thorax is strongly bowed and has short abdominal spines. The head has long head horns and the antennae have many short black spines (Brown, 1981; DeVries, 1997).

Geographical Distribution:
Heliconius erato is widespread throughout Central America and South America. The map below shows an approximate representation of the geographic distribution of this species. The original data used to draw these maps are derived from Brown (1979) which is available at Keith S. Brown Jr. (1979). Ecological Geography and Evolution in Neotropical Forests.

Februa Cracker - Hamadryas februa - HÜBNER, 1823

Kingdom: Animalia
Phylum: Arthropoda
Class: Insecta
Order: Lepidoptera
Family: Nymphalidae
Sub-family: Nymphalinae
Scientific name: Hamadryas februa

Introduction:
There are 20 members of the genus Hamadryas, commonly known as Crackers due to the ability of the males of several species to produce a clearly audible sound which is similar to the crackling of bacon in a frying pan.

The sound is produced as the butterflies take off, and is made by twanging a pair of spiny rods at the tip of the abdomen against bristles on the valvae ( the male's anal claspers ). Only males can produce the sound, but both sexes can detect it - their wings have tiny hollow cells covered in membranes which vibrate in response to sound and stimulate nerve endings. The purpose of the sound is not fully understood : it may deter competing males from occupying the same territory, and may also act as a trigger to initiate the first response from a female during courtship.

Hamadryas butterflies use their ears to detect crackling noises made by territorial males. The sound is made by twanging 2 tiny prongs on the tip of the abdomen against bristles on the valvae. The males habitually bask on tree trunks, where they wait to intercept passing females.

All Hamadryas species have a beautiful calico pattern on the upperside. In many there is a series of submarginal ocelli on the hindwings, and distinct kidney-shaped stigmata in the discal cells of fore and hind wings. In several species such as februa and glauconome the ground colour is greyish and the pattern acts as an extremely effective camouflage against the bark of trees. In other species such as amphinome, laodamia and velutina the wings are velvety black with a blue sheen and a pattern of bright blue spots.

Most Hamadryas species are found only in Central and South America, although 8 have been recorded sporadically in the southern USA.

Hamadryas februa is the commonest and most widespread species, found from southern Texas to Uruguay and Paraguay.

Habitats:
This species is found in degraded rainforest and deciduous forest habitats, including orchards and the forested margins of cattle ranches, at altitudes between sea level and about 800 metres.

Adult behaviour:
In common with other Hamadryas species februa can often be seen basking on tree trunks, in a head-downward position and with the wings flattened against the bark. They will bask in this position for long periods to await potential mates. They commonly settle at a height of about 2 metres but if disturbed by humans they fly up and resettle higher up, either on the same tree or on another nearby. They remain high in the trees until the intruder leaves, and then descend the tree trunk in a series of short flights, dropping a short distance each time until after several minutes they resume their original position.

The butterflies are active from sunrise to sunset, and are rarely seen away from tree trunks, but also sometimes bask on rock faces or tree foliage. On a few occasions I have also seen them settling on the ground in lightly vegetated forest clearings.
