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: Unable to locate host plant/tree. Caterpillars are scaling the walls of our house and redwood fencing. I have observed at least 5 or 6 dozen individual 'pillars. Have been at this residence for 20 years. Only one neighbor has confirmed 'pillars at their location.

Coordinator notes: Tent caterpillar, almost certainly. I cannot see the white bristles to the side, but there should be some. Kelly
