ID requested for Unknown caterpiller
GREETINGS FROM INDIA!!!!
Dear Sir/Madam,
I am sending herewith some early stages images of unknown hesperiid butterfly. Specimen collected from Kolkata, West Bengal, India. You are requested to check the same and give us the ID. (I guessed its a Pelopidas species but not sure for which butterfly).
Regards,
Rajib Dey
Attached Images
Caterpillar identification is particularly difficult because so little is known about them.
However the head markings are nearly identical to the pale form of the 5th instar of Hyarotis adrastus.
The facial triangle is small & above are two pale parallel bands.
The mouth parts are flanked by bulges like bulging cheeks.
The dark form has the central zone above the triangle dark brown.

H. adrastus in India showing only the dark 5th instar.

The pupa is different though.
My guess is probably another Hyarotis.
The next commonest in India is H. microstictum .

Thanks a lot Sir. I am just asking one thing for my knowledge. If I go for journal publication on about it then is this required for genital dissection to approved the specimen, please guide. Indian Entomologist suggest me that Sir W.H. Evans (1949) states that as per genital based.
