Doubleday 1845 - The Courtesan

Koh Samui only.

A fascinating species. The female is polymorphic (has many different forms), of which three named ones have been found on Samui, so far. There are also innumerable intermediate forms which have not been named. The female forms mimic the distasteful Euploea (Crow) species of the family Danainae. Normally, a mimic will live in the same area as the model, but here we have two forms, f. isina and f. euploeoides which mimic Euploea radamanthus, a species not yet found on the Island, though is found just over the water on the mainland, near Donsak, and should be expected to be found here eventually.

This is primarily a species of secondary vegetation. Its hostplant is a very common weed on waste ground, though the butterfly, itself can, at no time, be described as common.
