Ephemerella (Hendricksons, Sulphurs, PMDs) Mayfly NymphEphemerella (Hendricksons, Sulphurs, PMDs) Mayfly Nymph View 6 PicturesThis pretty Ephemerella nymph has really weird markings. It has one band on the tibiae (

and a thin but distinct dorsal (Dorsal: Top.) stripe faded in the center which looks very different from the stripes on Ephemerella needhami and Ephemerella aurivillii. It definitely has the fan tail characteristic of the Ephemerella genus.

Phryganeidae Caddisfly LarvaPhryganeidae  Caddisfly Larva View 5 PicturesThis "specimen" is actually two caddis larvae fighting each other over a case. The case is a hollow tube; one larva would go in the back end, presumably bite the other, and chase it out. The invader crawled forward into the case while the other one fled, and then it went around to the back and bit the first one. They did this several times, and I recorded it on video.

Eurylophella (Chocolate Duns) Mayfly NymphEurylophella (Chocolate Duns) Mayfly Nymph View 5 PicturesThis nymph is an extremely early instar (Instar: Many invertebrates molt through dozens of progressively larger and better-developed stages as they grow. Each of these stages is known as an instar. Hard-bodied nymphs typically molt through more instars than soft-bodied larvae.).

Baetidae (Blue-Winged Olives) Mayfly NymphBaetidae (Blue-Winged Olives) Mayfly Nymph View 5 PicturesThis nymph has only two real tails. The third is present, but too short to see in these pictures. It has particularly small gills and indistinct gill veinlets (Veinlet: Short insect wing veins connecting the major longitudinal veins to the wing margin.).
