Female Ephemerella (Hendricksons, Sulphurs, PMDs) Mayfly SpinnerFemale Ephemerella (Hendricksons, Sulphurs, PMDs) Mayfly Spinner View 8 PicturesI've seen Ephemerella invaria with green egg sacs and Ephemerella subvaria with yellow one. This one seems too large for dorothea. So what is it? I'm not sure.

Many females of this species were gathered in tight clouds to lay their eggs over the riffles in a mid-sized Pocono stream right at dusk. It would have been a fishable spinner fall if I'd stuck around to wait for them.

Female Leptophlebia (Black Quills and Blue Quills) Mayfly DunFemale Leptophlebia (Black Quills and Blue Quills) Mayfly Dun View 7 PicturesI collected this mayfly after user Al514 tipped me off to the presence of some Leptophlebia mayflies I didn't seem to have yet with his ID request of a male dun. This seems to be of the same species. I also collected a female spinner. Based on that spinner, I can tell that this is either Leptophlebia cupida or Leptophlebia nebulosa, but I can't tell which.

Unfortunately none of the specimens I collected made it through the hot, sunny day very well. So the pictures aren't great, but they're better than nothing.
