Fly Imitations by Orvis
 This is the only Baetis nymph I found in my January 31st (read: not sane) sampling in 2004. I looked at this one under my small microscope and wrote down some useful identification features which aren't really visible in the pictures from my camera. This nymph had conspicuous gill veinlets (Veinlet: Short insect wing veins connecting the major longitudinal veins to the wing margin.), a pointed, slender 7th gill, tail bands on the middle and tip, and abdominal segments 5, 9, and 10 are definitely pale, with segment 8 in-between, debatably pale.

This mayfly was collected from the Upper Midwest on January 31st, 2004 and added to Troutnut.com on January 25th, 2006.
