Common Sergeant Butterfly Athyma perius

The Common Sergeant Butterfly is native to South and Southeast Asia. The topside is black with white bars and spots whereas the underside is bright tan with white and black markings.

Male and female have a similar appearance. The topside looks similar to several other tropical butterflies, related and unrelated. In particular its topside is similar to the Sailer butterflies of the same region (which also have a tan underside but have no black spots on the third bar) and the female Orange-banded Shoemaker of the Americas (without the rust spots).

The orange-tan underside with black spots on the third white row (also shown on the dark topside). The body is dark on top but white on the underside.
