Purdue Public Health and Medical Entomology: Diseases such as West Nile virus and Lyme Disease cause considerable human mortality and morbidity. Public education is the key to the prevention and control of vector-borne diseases. The goal of the Purdue Public Health Entomology Program is to reduce transmission of vector-borne diseases through public education. We offer a variety of educational materials and training opportunities to help the public learn about vectors, vector-borne diseases, and their control.

Caterpillars, Butterflies, and Moths
OK, there are oodles of books and websites that are devoted to identifying adult moths and caterpillars. But very few are dedicated to the lowly caterpillar, which you kind of need to have around if you want to have butterflies and moths. Here are a few sites I've found to be useful.
