The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.
This female Hex dun emerged around 11 pm, one of relatively few on the water as I rushed back to the truck to beat an approaching thunderstorm. Her tails in reality were longer than shown in the picture, but they broke off.
This mayfly was collected from the Namekagon River in Wisconsin on June 18th, 2021 and added to Troutnut.com by Troutnut on June 20th, 2021.
