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: A massive number of tent caterpillars were observed on Antelope Bitterbrush (Purshia tridentata) in Plumas National Forest. The same caterpillars were observed in Lassen National Forest.
