Encyclopedia
The White-bar Bushbrown (Mycalesis anaxias) is a species of satyrid
butterfly found in South
and Southeast Asia
. In South Asia, it inhabits Sikkim
, eastwards through the hill-ranges to Assam
, Cachar, Myanmar
and Tenasserim. Also in Southern India, in the Nilgiris
and Travancore
.
Wet-season form: male and female: Upperside dull van dyke-brown, paler in the female; subterminal and terminal fine lines on both fore and hind wings fulvescent: cilia brown. Fore wing with an oblique white preapical short band not quite reaching either the costa or the termen. Underside : fore wing: basal area up to the white band, and in a transverse line from lower end of band to dorsum, blackish brown ; terminal margin beyond broadly paler brown; a white-centred fulvous-ringed black ocellus in interspace 2, and two preapical, smaller similar ocelli, followed by a very sinuous subterminal and a straighter terminal dark brown line. Hind wing: basal two-thirds blackish brown, terminal border broadly paler, bearing normally seven ocelli similar to those on the fore wing, and subterminal and terminal dark brown lines.
Dry-season form.— Upperside as in the wet-season form. Underside differs in the ocelli being indistinct or absent, and the subterminal and terminal dark lines on both fore and hind wing absent or very faint; the terminal margins are broadly rufescent brown, fading inwardly into lilacine, the oblique white bar on the fore wing outwardly diffuse- Antennae, head, thorax and abdomen dark brown; the antennae ochraceous towards apex.
Wingspan: 51–60 mm. Male sex-mark in form 1.
