The Insect Identification Service is part of Oregon State University Plant Clinic. Insects, arthropods, and their damage are identified. It provides services for the public, but encourages those interested in having a sample identified to first contact their county office of the OSU Extension Service.
Consult the website for sample submission instructions.
