tiny Mayfly-like insects - Caenis
Hollis, Hillsborough County, New Hampshire, USA
February 6, 2005
Came to UV lights set up in marshy stream locale. I've set up my UV light here twice, and each time the horizontal skirts of my moth sheet were covered with these tiny Mayfly-like insects. They did not cling to any vertical surfaces and seemed to die in great numbers as they sat under the UV light.

Mayfly identification
Jim-

Your "tiny Mayfly-like insects" are family Caenidae, genus Caenis. However, they usually emerge between June and September, not in February.
