Dart

Yes, cannot tell anything. Still, exciting to put up a new species. Keep an eye out for more opportunities for detailed photos of this butterfly, see if you can really nail it down. Dave

You should go ahead and put niobe up as an ID. I am seeing the difference now, in the much darker niobe, even though everything else is the same. Dave

Woe! I can't tell the difference between niobe and omaha. But, given your location, I would definitely say you were right. Pity you didn't get a photo of the underside, as there are two sub-species. A good piece of detective work - well done :) Dave

Similar with my spotting, Potanthus flavus, http://www.projectnoah.org/spottings/32892012

I think it is Dark Palm Dart Telicota ancilla (Herrich-Schäffer, 1869)
