Male Rhithrogena undulata (Small Western Red Quill) Mayfly SpinnerMale Rhithrogena undulata (Small Western Red Quill) Mayfly Spinner View 13 PicturesThis male was collected at the same time as this female and is likely the same species.

It keys pretty clearly to Rhithrogena undulata using the key in Traver 1935, although the size is larger than expected for that species in that source.
