Mayfly Species Rhithrogena undulata
These are often called Small Western Red Quills.
This is one of the two most common species of Rhithrogena.
This 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.
