Arhopala bazalus explained

Arhopala bazalus, the powdered oakblue, is a lycaenid or blue butterfly first described by William Chapman Hewitson in 1852.^[1] 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 silveryreflection. In the female we notice a deep violettish-blue spot in the basal portions of the wings.^[2]
