Arhopala bazalus

Template:Short description Template:Speciesbox Arhopala bazalus, the powdered oakblue, is a lycaenid or blue butterfly first described by William Chapman Hewitson in 1852. It is found in Myanmar, mainland China, India (Assam, kerala and Sikkim), Indochina, Japan, the Philippines, and Taiwan.

Description

The male is almost without any blue lustre; both wings are of a dull dark brown colour, only in a certain light the upper surface exhibits a feebly bluish, somewhat silvery reflection. In the female we notice a deep violettish-blue spot in the basal portions of the wings.
