The focus is to document the variety of caterpillars and larvae that inhabit Southwestern United States; Arizona, California, Colorado, Nevada, New Mexico, Oklahoma, Texas and Utah. This makes up about one forth of the United States. Since Texas is also counted in the Southeastern states; caterpillars in Louisiana, Mississippi, and Arkansas are welcome.
