Deramas jasoda jasoda

de Niceville 1889 - Silver-Marked Bluejohn

Koh Pha Ngan only.

This is a very rare species, found at the fringes of forests. Seen for the first time on the Island on 26 June 2012.

The photo of the male upperside shows that this is D. jasoda and not D. livens as originally thought. There is a small blue triangle shaped marking at the cell end on the forewing, which is not present in D. livens. This specimen was found dead at precisely the same location, 2 days after the live female shown was photographed. Coincidence suggests that they are the same species.
