TL Seow: Cheers.

Thanks Dr Seow for the explanations!

Would this then by P. omaha?

Would you consider the veins in this photo to be dark dusted?

Thanks!

[Psyche]

Yes. I would say they are P. omaha.
At least the HW veins continue as dark dusted crossing the marginal zone, to the margin.
Ideally the upperside HW would be available for confirmation.
Perhaps some gene introgression (hybrid element) in the male.
The female is more obvious comparing with typical P. ganda females.
P. ganda.

Ok thanks for clarifying Dr Seow.

Apologies for adding on but two more skippers for verification please.

Could this be Erionota thrax based on the almost straight termen and acute forewing apex?

Also, is the following sufficient to ID it to Astictopterus jama?

Thank you!

E. acroleuca is by far the commonest species in Singapore as its larva feeds on various palms while that of E. thrax & torus feed on Banana which would be a rare plant in Singapore.


E. acroleuca. Smaller than the other two. FW 25/27 mm.
Male antennal club wholly white above; female about half white.
FW margin straight.
HW patch constricted/narrowed in the upper half.

Can I add on this species.

Could this be Potanthus serina?
