The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.
This Baetisca obesa dun hatched out in my aquarium from nymphs collected a couple weeks earlier.
This mayfly was collected from the Neversink River (aquarium-raised) in New York on May 23rd, 2007 and added to Troutnut.com by Troutnut on June 4th, 2007.
