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

Male Cinygmula ramaleyi (Small Western Gordon Quill) Mayfly Dun Pictures

This dun hatched out from a nymph in my aquarium on July 16th, after being collected July 10th. It is probably of the same species as this nymph, and this dun which also hatched from one of these seemingly identical nymphs.

This mayfly was collected from Nome Creek in Alaska on July 10th, 2011 and added to Troutnut.com by Troutnut on July 16th, 2011.
