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!

Coordinator notes: This ID is tentative. Andrew Warren's Oregon book was inconclusive about species status of chalcedona and colon, but said west of the Cascades pop[ulations included colon at subspecies status of chalcedona, which would be nominate colon the species. The distribution of the two species is problematic, I tend to accept colon as a species (I have wallacensis from the Umpqua River on the east side of the Cascades)-Ken Davenport
