Think this is a Grey Sailor

Getting rusty at my ID :P, looks like a Neptis leucoporos cresina (Grey Sailor)

Look like a Common Sailor to me. :-)

Thanks CP ,

Looks like it is a Common sailor , it lacks the white stripe across the abdomen... and the triangular cell 'spot' is not elongated.

Soon Chye ,

I think the 3rd picture in the Grey Sailor Checklist is a Common Sailor too..

Thanks, will take a look & correct
