**Female Drunella flavilinea (Flav) Mayfly Dun Pictures**

Classification

Kingdom Animalia (Animals)

» Phylum Arthropoda (Arthropods)

» Class Insecta (Insects)

» Order Ephemeroptera (Mayflies)

» Family Ephemerellidae (Hendricksons, Sulphurs, PMDs, BWOs)

» Genus Drunella (Blue-Winged Olives)

» Species flavilinea (Flav)

I can't be certain of the ID of this female dun, but I'm calling it Drunella flavilinea for three reasons: 1) the known abundance of "flavs" on the Henry's Fork, 2) clear differences in coloration from my confirmed specimens of Drunella coloradensis, which is the main lookalike, and 3) the habitat (a sizable river in a wide mountain valley, rather than a small, high-altitude stream) suggests it's not coloradensis.

This mayfly was collected from the Henry's Fork of the Snake River on July 31st, 2020 and added to Troutnut.com on August 16th, 2020.

I accidentally preserved this one in alcohol before remembering to do the length measurements, so I fished it out of the drink for this photo. Female Drunella flavilinea (Flav) Mayfly Dun from the Henry's Fork of the Snake River in Idaho

Looking for picture of successful Flav pattern. With materials list and explanation of any critical tying steps. Both dry and nymph.
