Ideopsis similis persimilis
Moore 1879 - The Blue Glassy Tiger
Koh Samui and Koh Pha Ngan.
This is one of the commonest butterflies on Samui. It is very similar to Ideopsis vulgaris, the main difference being the shape of some of the basal spots in spaces 2 & 3 on the forewing, which, in I. similis are elliptical and I. vulgaris, wedge shaped. Also, the cell-end spot is only slighly outwardly indented in I. similis, but deeply indented in I. vulgaris.
It can be found anywhere on the islands except for in deep forests.
