In comparing the larva of this with that of M. biggsii there is some differences.

M. biggsii from BC checklist.
http://www.butterflycircle.com/check..._L4_8mm_01.jpg


In M. biggsii larva there is a black squarish patch in segment 5 which would be the 2nd abdominal segment.


In your larva the black area extend from segment 5 to 6 (abdominal segment 2 & 3.)


This suggest your butterfly is not M. biggsii, assuming the larva & the adult are the same.



TL Seow: Cheers.
