I am in a bit confusion identifying this insect. Please help me providing its identity.
This looks a lot like the banana skipper, Erionota thrax, or a closely related butterfly belonging to family Hesperiidae.
It's does look like the banana skipper Erionota.. Can you indicate the host plant in which you reared?
Dear Syed Zahid Hasan,
It is most probably Erionota thrax, especially if it was found in rolled up banana leaf. I know the species from Indonesia.
Hope this helps,
for the coming year with NPPO of Suriname
Dear Syed Zahid Khan,
It is most certain that this is not the banana skipper, Erionota (Pelopidas) thrax.
Thank you, Matthew
I see from Butterflies of India that a common name of Ancistroides nigrita is the Chocolate demon!
Syed - A recent publication is referenced there too.
