Female Ephemerella subvaria (Hendrickson) Mayfly SpinnerFemale Ephemerella subvaria (Hendrickson) Mayfly Spinner View 3 PicturesThis one's a bit bedraggled because it was rainy and I had a hard time keeping anything dry, including the container I was putting mayflies in. I was practically juggling up there balanced on a rock trying to catch mayflies and trout at the same time.

Ephemerella subvaria (Hendrickson) Mayfly NymphEphemerella subvaria (Hendrickson) Mayfly Nymph View 3 PicturesHere's another nymph with the strange brownish coloring rather than the olive I usually see for subvaria. I suspect it's the same species and it's just wide individual variation.
