Delias eucharis,[1] the common Jezebel,[2][3] is a medium-sized pierid butterfly found in many areas of south and southeast Asia, especially in the non-arid regions of India, Bangladesh, Sri Lanka, Indonesia, Myanmar[3][2][4] and Thailand.

[4][5] On the underside, the forewings are similar but the black edging to the veins much broader, the upper two interspaces beyond the postdiscal transverse band tinged with yellow.

[4] Upper and undersides similar to those in the male, but the black edging to the veins and the postdiscal transverse bands on both forewings and hindwings are much broader.

[4] The common Jezebel are nomadic in behaviour and are found in a variety of environment including, but not limited to, temperate hill forests, tropical rainforests, dry open woodlands, and beach hinterlands.

The females can be seen flying amongst the trees in search of its food plants, while the males are more frequently observed visiting flowers for nectar.

Due to this habit apparently, it has evolved a dull upperside and a brilliant underside so that birds below it recognise it immediately while in flight and at rest.

Unlike most butterflies this species lays as many as twenty or thirty eggs on one leaf, in parallel rows, with equal intervals, and the larvae continue in some measure gregarious to the last, so that a large number of pupae are often found, at a little distance from each other, on a wall, or the trunk of a tree.

It is attached to the underside of a leaf or branch or any other suitable surface by a strong tail pad and a tight body band.

[7] This butterfly's ability to form dense aggregations as caterpillars and to feed on Loranthus has led to suggestions that they could be used for control of these mistletoes.
