The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.
This specimen unfortunately was blown away by the wind mid-way through the photographs, so I wasn't able to preserve it for an ID or get some of the other angles.
This stonefly was collected from Green Lake Outlet in Idaho on August 4th, 2020 and added to Troutnut.com by Troutnut on August 19th, 2020.
