The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.

Agnetina capitata (Golden Stone) Stonefly Nymph Pictures

I took a few closeup pictures of this stonely with my old camera and a microscope.

This stonefly was collected from Fall Creek in New York on November 15th, 2004 and added to Troutnut.com by Troutnut on April 12th, 2006.

The occipital ridge shows this specimen to be in the subfamily Perlinae. The distinctive head markings connote a form of Agnetina capitata I've seen in photos of Midwestern specimens. I'm not positive on this one as I can't vouch for the accuracy of the photos compared with it, but I hated to see this guy languish on the family page when it's clearly Perlinae.

Compare the pronotal and head markings with this specimen. Heck, the whole dorsum is a good match. It seems a credible site.
