Pacific Northwest Moths is a comprehensive source of information about more than 1,200 species of moths.

Drawing from the knowledge of moth experts and specimen records from the region’s major insect collections, this site features detailed species accounts, high resolution photographs, and an interactive identification key for every Pacific Northwest moth species within the families Drepanidae, Uraniidae, Lasiocampidae, Saturniidae, Sphingidae, Notodontidae, Erebidae, Euteliidae, Nolidae, and Noctuidae.

Explore this site to identify a moth that you have found, or to learn about the amazingly diverse moths of our region. Because the site also works on mobile devices, it serves as an electronic field guide to the region's moths!

New Map Feature!: Each species account now has a filter under the map, allowing you to reduce the map data to only the locations (red dots) from which we have one or more photos of that moth species.
