Dry Season form of Common Bush Brown

The Common Bushbrown (Mycalesis perseus) is also known as Dingy Bush brown is a species of satyrine ies found in South Asia and Southeast Asia. It can be seen amid dry forest leaf litter inside NEERI urban forests. It is active mainly during mornings and evenings. It has jerky low flight among grasses and undergrowth. Prefers well wooden areas. Common bush brown is partial to tree sap, over ripe fruits, cattle dung while, males also visit damp patches. They are on the wings throughout the year. Appears mostly in drier areas.

Adults are dark brown with weak bands on hind wing, outer margin of hind wing irregular; lower surface brown to dark brown with a number of eye spots on both fore and hind wings, bands more obvious on both wings. Wing span is 38-55 mm. Wet and Dry season forms are different. Dry-season form of Male and female of this butterfly is quite similar. Upperside of the wings is dark to somewhat pale vandyke-brown in dry season and that is similar to wet season. Fore wing is with a white-centered, fulvous-ringed, black ocellus in interspace 2, and rarely a very small but similar ocellus is present in interspace 5. Median ocellus is generally smaller in common bush brown. Underside brown, more or less suffused with purple and irrorated with darker brown minute transverse strigae; the transverse discal band is obscure, often merely indicated by black dots at the veins, occasionally bordered outwardly by an ochraceous diffuse band. Ocelli are obsolescent, but when present they are mere minute dots their arrangement on the hind wing as it was in the wet-season form. Wings in dry season expand from 42-54 mm.
