Capnia umpqua - voucher specimens in alcohol - Capnia umpqua - Male Female
Healdsburg, Russian River, Sonoma County, California, USA
February 2, 2013
Size: 5.5-6 mm body length
Many Capnia nymphs are still not described so the ID is tentative, based on association with adults (thumbnails below). Genus was determined with Merritt, Cummins and Berg (2008) as well as Stewart and Stark (2002). Species of nymphs is tentatively determined from Stewart and Drake's "Larvae of five species of the winter stonefly genus Capnia (Plecoptera: Capniidae) from California". Adults were identified to genus using Merritt, Cummins and Berg (2008), and to species using Baumann and Stewart's "What is Capnia umpqua Frison? (Plecoptera: Capniidae) distribution and variation of terminalia". Female on left, male on the right.

"...the ID is tentative"
this requires clarification: why is it tentative if you have the reared adults of both sexes?

 
rearing of Capnia umpqua
Sorry, should have been more clear. I haven't reared them. Nymphs and adults were collected in the same area at the same time.

 
oh! in that case, images should be unlinked
please note that only images of the same individual may be linked, it's an important rule; this means that your large original series should be broken down into 5 separate series; i did this rather tricky job here, cross-referencing them the best i could -- please see edited Remarks at the first image of each series, and note the format used to insert thumbnails [thumb:xxxx] and footnote links [cite:xxxx]

 
Capnia update
I appreciate your work on the Capnia series. Must have been a pain. I'll try not to make the same mistake again.

 
yeah, it was a pain...
...but i don't mind having some pain as long as you post all those nice things that augment the guide, and i'm sure you'll learn all those pesky technical minutiae soon.
keep them coming!

 
well, I've got...
...plenty more and I'm not afraid to inflict them on other people.
