The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.
This large female Leptophlebia spinner emerged from a nymph I was holding in my room one night. I didn't have time to photograph her and she molted into a spinner before I was home from work in the evening. So here she is as a spinner. I wish I had more photos at more angles, but she flew off and I couldn't find her.
This mayfly was collected from unknown in Wisconsin on May 18th, 2004 and added to Troutnut.com by Troutnut on January 25th, 2006.
