Female Ephemerella dorothea infrequens (Pale Morning Dun) Mayfly Spinner View 9 PicturesI'm calling this one Ephemerella dorothea infrequens because it was collected along with two males that positively ID to that species.

Added to Troutnut.com by Troutnut on July 18, 2019

Female Formicidae (Ants) Ant Adult View 6 PicturesThis specimen began with wings, but they were lost during handling. The reddish abdomen was semi-translucent and almost seemed to glow in the sunlight, and big brown trout were going crazy for them.

Collected August 22, 2018 from Mystery Creek #227 in Montana
Added to Troutnut.com by Troutnut on June 13, 2019

Female Suwallia pallidula (Sallfly) Stonefly Adult View 6 PicturesI didn't key this one out under the microscope, but I just keyed a similar one from Montana and this one matches the macroscopic appearance closely enough that I'm guessing it's the same thing.
