Pathysa aristeus hermocrates

C. & R. Felder 1865 - The Chain (Stripe) Swordtail

Koh Samui only.

A very rare species on Samui (though frequently encountered on the mainland), which appears to be single brooded, a rare phenomenon for butterflies in the tropics. There is a very similar species found on the mainland, further north, P. nomius, where the main distinguishing mark is that on the forewing, the thin pale submarginal line has the last spot but one from the top slightly dislocated out.

Mainly a forest species, usually found near water.
