This is the first of it's family I've seen, collected from a tiny, fishless stream in the Cascades. The three species of this genus all live in the Northwest and are predators that primarily eat stonefly nymphs Merritt R.W., Cummins, K.W., and Berg, M.B. (2019).

Roger is right, IMO. Where & when was this fly collected? Size?

Hi Byron,
The latest photo is of a mayfly in an entirely different family from your first one. Do you have answers to my questions posted above?

Ento,
I know, but it also is up for identification. Pic. Is a mayfly from Argentina.
Given its speckled nature and that it is from a lake I thought Calibaetis. But it has large hind wings. Could it be related to the Calibaetis??
Thanks
