Small Minnow Mayfly  - Cloeon dipterum - female

Small Minnow Mayfly - Cloeon dipterum - Female
Medford, Middlesex County, Massachusetts, USA
May 6, 2008
Seen on a shady side of a wall in the morning. Didn't move.

Moved

I believe...
this is probably the female subimago of Cloeon dipterum. Notice the tail and body markings and the lack of any (visible) hindwings. You can see the conversation about this species here and here. Although photos of the female subimago have not been as easy to find as those of the female imago (all European sources), you can compare to the top image here.

Baetidae
Peter-

This would appear to be a female subimago of family Baetidae, perhaps Baetis flavistriga.

 
Thank you
Thanks Roger, and Ron. Baetis flavistriga is not in the guide yet.

 
If you have a specimen...
that has no page you can request one. Click on the FORUM tab. There will be a forum for requesting new species pages. If an editor agrees that a new page is warranted, one will be created.
