Common Pierrot (Castalius rosimon)
Last Observed: April 2016 – Koh Chang
Last Observed By: Michael Erik Maria Finder
The Common Pierrot is presumably named after the creepy and rather unpleasant Italian clowns of the same name. It’s black and white you see.
It actually has a really attractive pattern though with all kinds of leopard-like spots on a white background.
It is a South Asian native butterfly that is a member of the lycaenid family of butterflies.
