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: Two caterpillars on whorled milkweed, Asclepias verticillata, on a limestone glade/woodland complex. It was sunny in the mid-70's. Surrounding plants are woodland sunflower, big bluestem, river oats grass and blue sage.
