PNW Moths is an interactive identification key to the more than 1,200 moth species featured on the Pacific Northwest Moths website (pnwmoths.biol.wwu.edu). Designed for people with no prior knowledge of moth identification, the key narrows the list of possible species in response to responses users give to easy-to-understand questions about seasonality, location, size, and color patterns.

PNW Moths has photos of all of the species known from the region in the families Drepanidae, Uraniidae, Lasiocampidae, Saturniidae, Sphingidae, Notodontidae, Erebidae, Euteliidae, Nolidae, and Noctuidae, and is updated regularly in response to new discoveries.

PNW Moths allows users to record information and photos from moth observations to their mobile device and upload their observations to the PNW Moths app server, making it a terrific resource for students, educators, naturalists, and anyone else interested in identifying moths in this region.
