Entomology

University of Wyoming Extension

Local Options

If you have an insect (or any other small arthropods) you would like to have identified you can take it to your local University of Wyoming Extension office. The knowledgeable personnel who work there can often identify insects, especially common pests immediately. Sometimes a species level identification can be made but often identification of the insect's Family is all that is necessary for good management recommendations. If the local UW Extension personnel can't help you they will then send the insect on to the University for identification.

A quik way to get an insect ID is to first send good in-focus photos of it to: insectid@uwyo.edu or 307-399-
9344 (photos sent via cell phones will often be reduced in resolution making it hard to see details). If I
can’t identify from the photos I will ask for a specimen(s).

If you need to, you can submit the insect, spider, or other arthropod with a completed Insect ID Form

• Make sure you obey postal regulations and pack the creature you are sending in such a way that it won't mold, rot, or be crushed before it gets to the University.
• Identifications will be done as soon as possible but if the personnel are out of the office doing research it may take a while to get a response.
• Please include an email or phone number as that helps you get a speedy response.
• Also include as much information about the insect sample as possible.
• If it is a plant pest, including a sample of damage it is causing the plant will aid identification.
• If the creature has bitten someone and there are any health concerns they should seek immediate medical attention rather than waiting for official identification the offending pest.
