Our summer fundraiser has arrived, and we need your help!
We depend on donations to keep Butterflies and Moths of North America freely available. If everyone who uses this resource makes a donation, we could cover our ongoing costs, develop new features, upgrade the system, and maybe even remove those pesky ads. Please make a one-time or recurring donation to show your support for this valuable source of information. Thank you!
Observation notes: On a large Mock Vervain bush bordering a small partially shaded trail, I spotted this brilliant yellow butterfly with a single dark spot on the dorsal forewing. It also exhibited delicate scarlet etching along the edge of the wings and some veining. There is also a distinctive, almost comma-shaped, point on the outside forward edge of the wing. On the same bush a Painted Lady and a Duskywing were also feeding together.
