Pteronarcys californica

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

Troutnut is a project started in 2003 by salmonid ecologist Jason "Troutnut" Neuswanger to help anglers and fly tyers unabashedly embrace the entomological side of the sport. Learn more about Troutnut or support the project for an enhanced experience here.

Female Leucrocuta hebe (Little Yellow Quill) Mayfly Dun Pictures

I found this dun on the same piece of stream as a similar spinner, probably of the same species.

This mayfly was collected from Mystery Creek #43 in New York on September 19th, 2006 and added to Troutnut.com by Troutnut on October 4th, 2006.

Haven't checked any keys to verify, but most of the little late-season Cahill-looking duns are Leucrocuta. If I had to guess at the species, I'd say hebe (Little Yellow Quill). It is probably the most common L. spp. in the East and has a long hatching period that extends well into the fall.

I would also agree that the spinner you photographed is the same species.
