Heya guys....Really Really sorry for being too late...Today i will be discussing about COMMON CROW BUTTERFLY.
COMMON CROW BUTTERFLY(Euploea core):Itis a common butterfly found in South Asia. In India it is also sometimes referred to as the Common Indian Crow, and in Australia as the Australian Crow. It belongs to the Crows and Tigers subfamily of the Nymphalidae (Brushfooted butterflies).The Common Crow is the most common representative of its genus Euploea.The Common Crow (Euploea core) is a glossy black butterfly with brown underside with white marks along the outer margins of the wing. The wingspan is about 8-9 cm and the body also has prominent white spots.
MALE COMMON CROW BUTTERFLY:Male's upperside dark brown, broadly paler along terminal margins; Fore and hind wing with subterminal and terminal series of white spots; on fore wing the former more or less oval, curved inwards opposite apex, the latter series often incomplete, not reaching apex, the spots smaller; often there is a small costal spot, and very rarely a spot in apex of cell and one or more discal spots; on the hind wing the inner series of spots are elongate, the outer conical. Underside similar, but ground-colour more uniform; cell, costal and discal spots on both fore and hind wing nearly always present.
MALE COMMON CROW
FEMALE COMMON CROW BUTTERFLY:Female's hindwing broadly ovate. Upperside dark brown, broadly paler along the terminal margins, especially on the fore wing. Fore wing with more or less incomplete and obsolescent series of subterminal and terminal small white spots, and a powdering of violaceous-white scales at apex, varying very considerably in extent from a mere trace of violaceous between the veins to a large and very conspicuous patch occupying the whole of the apex. Hind wing with a subterminal series of oval or inwardly conical and terminal series of more rounded white spots. Underside paler brown, the white spots larger, more clearly defined. Fore wing not violaceous at apex, a spot (sometimes absent) in apex of cell, and two or three discal spots. Hindwing: a spot in apex of cell, also sometimes absent, and a discal series of five small spots beyond. Antennae, head, thorax and abdomen very dark brown, and, the antennae excepted, sparsely spotted with white.
FEMALE COMMON CROW
HABITAT AND HABITS:It is found everywhere in India right up into the mountains till 8000 feet. Occasionally it swarms in the low, wet, jungles of South India due to the abundance of its foodplants which are spread over three orders of plants.The butterfly, being protected by its inedibility has a leisurely flight. It is often seen flying about shrubs and bushes in search of its host plants. It visits a large variety of flowering plant species.
LIFECYCLE OF COMMON CROW
EGGS:Eggs are laid on the underside of young leaves of the host plants. The egg is shiny white, tall and pointed, with ribbed sides. Just before hatching the eggs turn greyish with a black top.
CATERPILLAR:The caterpillar is cylindrical, vividly coloured and smooth. It has alternate white and dark brown or black transverse bands.The caterpillar bears four tentacle-like appendages, three towards the front and one at the back. All of them are curved backward at the tips.
PUPA:The pupa of this species is shiny golden in color. The wing margins are marked with broad colourless bands. The abdomen has a row of black spots on each segment. The cremaster is black. The pupa later turns black.
