Male Maccaffertium terminatum Mayfly Spinner Pictures



 I 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.

This mayfly was collected from the West Branch of the Delaware River on June 7th, 2007 and added to Troutnut.com on June 8th, 2007.
