Online Insect Identification Tool

This online insect identification tool is brought to your by the UW-Madison Department of Entomology and the UW-Madison Insect Diagnostic Lab.

Visit the right sidebar to search through 200+ Wisconsin insects by name, type, or by photo.  While certain insects can be found across the country, many insects can be region-specific.  Thus, this online tool is most relevant for residents of Wisconsin and the Great Lakes Region.  If you aren’t able to identify your particular insect or would like additional information, visit the main Insect Diagnostic Lab website.

In addition, there are a number of UW-Extension factsheets and other resources available for insect pests under the “pest resources” menu.
