Our summer fundraiser has arrived, and we need your help!
We depend on donations to keep Butterflies and Moths of North America online and free. 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: Was visiting Pikes Peak State Park near McGregor, IA. It was a crisp, sunny fall day, with temperatures in the low 50s. I sent photos to the Iowa State University Entomology Department to help with identification. I at first believed it to be a Milbert’s Tortoiseshell, but the university believed it was a Compton’s.
