Caterpillars

Web of Destruction: Caterpillar pests of concern to PNW Nurseries

How do you identify a caterpillar? These websites might be helpful.

USGS Northern Prairie Wildlife Research Center: What kind of caterpillar is this? This leads to more specific info for the PNW, including Caterpillars of Pacific Northwest Forests and Woodlands (written by OSU's Jeffrey Miller) and University of Idaho's caterpillar identification resource.

Web Images of North American Moth Species at Furman University's website in South Carolina also has some caterpillar identification photos.

If you know the host plant on which the caterpillar feeds, HOSTS - a database of the host plants of the world's Lepidoptera.

Another very nice site to identify moths in the United Kingdom is appropriately titled UK moths.
