This website, created by the National Agricultural Pest Information System, brings together information on more than 500 different exotic pests. You'll find maps of each invader's spread, pictures, descriptions and other information about each exotic pest. It's a great resource for information about all types of exotic pests. The site is a joint effort of Purdue University, USDA's Animal and Plant Health Inspection Service, the National Plant Board, and the Center for Environmental and Regulatory Information Systems.
