This page includes an automated list of specimens in need of more detailed identification. Because my academic specialty is salmonid behavior and I'm not an entomologist by training, I can only partially keep up with accurately identifying all the invertebrates I collect. I haven't had time to develop the at-a-glance familiarity experts have with many western species, and keying them out is often time-consuming or impossible from photographs, even with all the closeups I take. So I still rely on the generous volunteer help of more experienced entomologists to keep up with specific IDs. This page is intended to facilitate that help and prevent specimens from falling through the cracks.


If you can help with an improved ID on any of the specimens listed, please comment on the specimen page or shoot me an email at jason@troutnut.com with the specimen ID number (visible in its URL) and identification. If you can provide the rationale for the identification in a public comment, so others can learn more from it, that's ideal -- but feel free to just drop the name if you're busy and you're somebody I already know and trust to get it right.


Each list is prioritized with the specimens most recently added to the site appearing first, regardless of collection date.
