Moved from Rhithrogena.

Rhithrogena sp.
Mulling over the very spotty information on Rhithrogena species, and decided this is much too large for R. jejeuna. Possibly it is R. gaspeensis, a large species whose larva is unknown.

 
Rhithrogena
It sounds like mayfly larvae need a good entomologist to sort them out.

Heptageniidae: Rhithrogena sp.
A very nice species, with the gills forming a ventral "sucker."
