Both nymphs were identified to genus using Merritt, Cummins and Berg {2008) as well as Stewart and Stark's "Nymphs of North American Stonefly Genera (Plecoptera)" (2002). Identification to species is simple for Calineuria californica since it's the only species in the genus. Hesperoperla pacifica is almost as easy since there are only two species in the genus,H. hoguei and H. pacifica. I used Baumann and Stark's article "Hesperoperla hoguei, a new species of stonefly from California (Plecoptera: Perlidae)" to identify Hesperoperla pacifica. Their paper can be seen here: http://biostor.org/cache/pdf/45/13/be/4513bea08a52c948d6ed015eb7908ff3.pdf

Neither stonefly is common in the area of the Russian River I've been sampling but they are both common in smaller creeks that are tributaries to the river. They're most commonly found in riffles and glides with a moderate to fast current and a substrate of medium sized gravel and cobbles.

Don't know how I (or others) failed to comment on these stunning photos previously, but . . . wow!
