Ephemerellidae (Hendricksons, Sulphurs, PMDs, BWOs) Mayfly Nymph Pictures

» Family Ephemerellidae (Hendricksons, Sulphurs, PMDs, BWOs)
 This is a really really really really tiny mayfly nymph. It has gills on abdominal segments 3-7 in the characteristic orientation for the Ephemerellidae family, and it has no fain tail as best I can tell, just uniform tail coverage with small black hairs of equal length. I think this one's too young to identify.

This mayfly was collected from the Upper Midwest on March 10th, 2004 and added to Troutnut.com on January 19th, 2006.
