30-7-2017 CENTRAL PARK, BUDAPEST - BANDED ORANGE HELICONIAN BUTTERFLY (Dryadula phaetusa)

Dryadula is a monotypic genus of the butterfly family Nymphalidae. Its single species, Dryadula phaetusa, known as the banded orange heliconian, banded orange, or orange tiger, is native from Brazil to central Mexico, and in summer can be found rarely as far north as central Florida. Its wingspan ranges from 86 to 89 mm, and it is colored a bright orange with thick black stripes in males and a duller orange with fuzzier black stripes in females.

It feeds primarily on the nectar of flowers and on bird droppings; its caterpillar feeds on passion vines including Passiflora tetrastylis. It is generally found in lowland tropical fields and valleys.

This species is unpalatable to birds and belongs to the "orange" Müllerian mimicry complex.

Prior to their mating season, males of this species congregate by the hundreds on patches of moist soil that contain mineral salts, a behavior known as mud-puddling. When they cannot find such deposits, the insects visit various animals to drink salty secretions from their skin and nostrils.

The genus Dryadula Michner, 1942, is monotypic; the type species is Papilio phaetusa Linnaeus, 1758 (Syst. Nat. 10 ed., 1: 478). The type locality, given as "Indiis", is supposed to refer to the West Indies or northern South America.

30-7-2017 CENTRAL PARK, BUDAPEST - 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.

30-7-2017 CENTRAL PARK, BUDAPEST - ATLAS MOTH (Attacus atlas)

Attacus atlas, the Atlas moth, is a large saturniid moth endemic to the forests of Asia. The species was described by Carl Linnaeus in his 1758 10th edition of Systema Naturae.

The Atlas moth is one of the largest lepidopterans, with a wingspan measuring up to 24 cm (9.4 in) and a wing surface area of about 160 cm2 (≈25 in2). It is only surpassed in wingspan by the white witch (Thysania agrippina) and Attacus caesar, and in wing surface area by the Hercules moth (Coscinocera hercules). As in most silk moths, females are noticeably larger and heavier than males, while males have broader antennae.

Atlas moths are named after Atlas, the Titan of Greek mythology (due to their size). In Hong Kong, the Cantonese means "snake's head moth", referring to the prominent extension of the forewing that resembles the head of a snake.

Their habitat is primarily dry tropical forests, secondary forests, and shrublands across South Asia, East Asia, and Southeast Asia, including Borneo.

In India, Atlas moths are cultivated for their silk in a non-commercial capacity. Unlike silk produced by the related domestic silkmoth (Bombyx mori), Atlas moth silk is secreted as broken strands and is therefore less desirable. This brown, wool-like silk, known as fagara, is thought to have greater durability. Atlas moth cocoons are sometimes used as small pocket change purses in Taiwan. There is ongoing research as to whether the silk of the Atlas moth can be used as a substitute for common silks. The quality of the heavier cocoons, less restrictive rearing conditions and competent properties of the fibers, makes the silk produced by the Atlas moth a potential alternative for common silks. A study concluded that the silk fibers of the atlas moth had about an 80% higher density of cells and growth compared to the silk fibers of the silk moth.

28-7-2017 MONTE CORONA, VALENCIA - CROSS ORBWEAVER SPIDER (Araneus diadematus)

The spider species Araneus diadematus is commonly called the European garden spider, cross orbweaver, diadem spider, orangie, cross spider, and crowned orb weaver. It is sometimes called the pumpkin spider, although this name is also used for a different species, Araneus marmoreus. It is an orb-weaver spider found in Europe, where it is native, and North America, where it was introduced.

A. diadematus has a holarctic distribution throughout Europe and across North America, from southern Canada to Mexico, and from British Columbia to Newfoundland.

Individual spiders' colourings can range from extremely light yellow to very dark grey, but all A. diadematus spiders have mottled white markings across the dorsal abdomen, with four or more segments forming a cross. The markings are formed in cells filled with guanine, which is a byproduct of protein metabolism.

Adult females range in length from 6.5 to 20 mm (0.26 to 0.79 in), while males range from 5.5 to 13 mm (0.22 to 0.51 in). Occasionally, the female will eat the male directly after mating. 

The legs of orb-weaver spiders are specialized for spinning orb webs. The webs are built by the larger females, which hang head down in the center of the web or remain hidden in nearby foliage, with one claw hooked to a signal line connected to the main orb, waiting for a disturbance to signal the arrival of prey. Prey is then quickly wrapped in silk and bitten, and the prey may hang on the web to be stored for later consumption. The initial bite serves to paralyze the prey and minimize the danger of the spider herself being stung or bitten, and the enzymes thus injected serve to begin liquefaction of the prey's internal structures.

Alongside the use of the web to capture other prey, the spiders are also cannibals and prey on each other, but this only happens just before, during, or just after sexual activity. They attack based on their size, sexual experience, and hunger levels.

A. diadematus is a reclusive creature and only bites humans if cornered or otherwise provoked. It responds to a disturbance by vibrating rapidly in its web until it becomes a blur, a reaction that is assumed to confuse potential predators.
