Sulfur spinner c. 9mm caught in spider web 7:00
I believe this to be Ephemerella invaria rather than E. dorothea. Both can be on this river this time of year. These 2 specimens were 8-9mm, a bit larger than dorothea usually get. Note these are two different individuals - a male dun and a female spinner - but both are invaria, I believe. 3 tails, yellow/olive or yellow/brown body. These two photos were both taken the next morning, after each had spent the night my refrigerator. See earlier photo of the dun, taken a few minutes after capture, which shows a much more yellow body color.

Reddish brown body, a touch of yellow. Grey wings. Note the projecting bump on leading edge of hind wing. 3 tails ,striped, reddish brown.
Decent size (14b or so), dark body. I saw 2 tails on it, one broke off before photo was taken. It's possible it had 3 tails. I may be able to check specimen to find out. Female (small eyes).
