A few of these tiny stoneflies were among the only species of aquatic insect adults in the air on this particular afternoon, with most of the action coming from a species of Epeorus mayfly. I somehow forgot to photograph this one on the usual ruler, but I recall it was very, very small, with an abdomen no more than 1mm in girth and the body, not counting the wings, probably just 5-7mm long.

This stonefly was collected from the Catskills on September 6th, 2006 and added to Troutnut.com on October 4th, 2006.

The stonefly in this series of photos is not a Capniidae. It is a Nemouridae, a female Amphinemura. The yellow abdomen has eggs inside. Message from a stonefly researcher from Pennsylvania.
