Celastrina albocoeruleus
Celastrina albocoeruleus, the albocerulean, is a small butterfly found in India that belongs to the lycaenids or blues family. Description Male upperside, forewing: blackish brown, a central patch that occupies the lower apical portion of the cell and the basal halves of interspaces 2 and 3 white; lightly suffused with iridescent lilacine (lilac-coloured) blue; this colour is intensified and spreads upwards over the dark brown along the basal portion of the costa, inwards right up to the base of the wing, downwards over three-fourths of the dorsal area from base and outwards from the white patch towards the termen; the ground colour occupies the apex very broadly, and posteriorly forms a broad border to the termen. Hindwing: lilacine blue, base and costal margin broadly suffused with fuscous; a large subapical patch diffusely white; finally, an anteciliary line black. Cilia of both forewings and hindwings white, turning to brown towards the apex of the forewing. Underside: white, the terminal markings generally prominent in other forms, more or less obsolescent in both forewings and hindwings in all specimens that the writer has seen. Forewing: the slender short line on the discocellulars and the discal transverse series of short detached lines pale brown,
