Arhopala hercules

Arhopala hercules is a butterfly in the family Lycaenidae. It was described by William Chapman Hewitson in 1862. It is found in the Australasian realm. Above the male is deep ultramarine, of a pure colour though with but slight lustre. In the typical form from Celebes the under surface shows an intensely lustrous greenish tinge, only the postmedian transverse band is well developed, quite straight; proximally to it some scattered spots.
