This one seems to lead to Couplet 35 of the Key to Genera of Perlodidae Nymphs and the genus Isoperla, but I'm skeptical that's correct based on the general look. I need to get it under the microscope to review several choices in the key, and it'll probably end up a different Perlodidae.
This is one of the most common Rhyacophila species in the East and Midwest, and it was reported by the Leonards as the most common in the Lower Peninsula of Michigan.
In 14 records from GBIF, adults of this species have been collected during May (57%) and June (43%).
