Pseudo-Gray Drakes
This common name refers to only one family.
Mayfly Family Metretopodidae
These are pretty much always called Pseudo-Gray Drakes.
The mayflies of this family are large and elegant as adults and among the fastest-swimming of all mayfly species as nymphs. Sadly only one species (Siphloplecton basale) has been reported to produce fishable hatches, and even those are exceedingly rare.

Male Siphloplecton basale (Pseudo-Gray Drake) Mayfly Spinner
View 6 PicturesI went to great comical lengths to swipe this spinner from the air with a little aquarium net I carry with me while I'm fishing. Siphloplecton basale spinners fly fast and high over the riffles, and there are never very many of them, so they're difficult to catch.
