Female
Ephemerella
(Hendricksons, Sulphurs, PMDs) Mayfly Spinner
View 8 Pictures
I'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.
