Maccaffertium terminatum Mayfly Spinner
View 11 PicturesI positively identified this specimen under a microscope with a good key. It was one of the more common species in a generally light mixed bag of mayflies over a big Catskill tailwater last night.
I swooped this one out of the air while it was mating with a female, so I can be certain about her ID as well.

View 10 PicturesA few days earlier I photographed this same specimen as a dun. The changes between dun and spinner seem particularly dramatic in this species.

Epeorus pleuralis (Quill Gordon) Mayfly Spinner
View 10 PicturesI spent (Spent: The wing position of many aquatic insects when they fall on the water after mating. The wings of both sides lay flat on the water. The word may be used to describe insects with their wings in that position, as well as the position itself.) most of the day looking for Epeorus pluralis duns or spinners without any luck on the major Catskill rivers. Finally in the evening I arrived at a small stream somebody had recommended, and when I got out of the car I was happy to find that I had parked in the middle of a cloud of male spinners.
