Lexias dirtea merguia


Tytler 1926 - The Black-Tip Archduke

Koh Samui only.

The two Lexias species found on Samui are impossible to tell apart on the wing. The most obvious difference is that this species has black tips to its antennae, and the other has orange tips. Both species show strong sexual dimorphism.

This is an uncommon forest species, and can often be found, in season, feeding of fallen fruit.
