Euthalia monina monina
Fabricius 1787 - The Malay Baron
Koh Samui and Koh Pha Ngan.
A most unusual species in which the male is polymorphic. It is normally females which show this particular character. Strangely, this polymorphism appears to be limited to Neomalaya only, although the species is far more widespread. A third named form, f. gardineri, which is similar to f. monina, but the blue is replaced by brown, has yet to be found on the Island.
The butterfly is very common, and can be found in forests and forest edges.
