Baetidae (Blue-Winged Olives) Mayfly NymphBaetidae (Blue-Winged Olives) Mayfly Nymph View 3 PicturesThis 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.
Collected January 31, 2004 from unknown in Wisconsin
