Baetidae (Blue-Winged Olives) Mayfly Nymph Pictures



 Close examination under a microscope revealed that this Baetid nymph has segment 5 pale, segments 8, 9, and 10 pale but less so, a middle tail almost as long as the outer tails, conspicuous gill veinlets (Veinlet: Short insect wing veins connecting the major longitudinal veins to the wing margin.), no bands on its tails, and pointed, slender 7th gills.

This mayfly was collected from unknown on February 7th, 2004 and added to Troutnut.com on January 25th, 2006.
