Hi Dr Seow,

Thanks for the IDs, but was just wondering if there’s any chance the Potanthus could be a serina? As the sighting was from Dairy Farm Nature Park in Singapore and from what I understand P. mingo isn’t on our national checklist yet.

Hi Dr Seow,

No. In P. serina FW spot 5 is smaller than spot 4 (often by 1/2 in the male)
You can compare the 2nd pic (spot 4 & 5 equal) with the P. serina male in the link given.
P. serina is a larger skipper. Here is another example.

P. mingo is one of those less well known Potanthus because they all look alike.
There are several photos identifiable as mingo
I think it is not that rare but routinely labelled as omaha.
