Baetisca (Armored Mayflies) Mayfly NymphBaetisca (Armored Mayflies) Mayfly Nymph View 4 PicturesI'm unsure which species this is: it lacks the usual features of B. laurentina, but it's small, so maybe it's just an underdeveloped 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.). Otherwise, it looks like it might be B. obesa.

Ephemerellidae (Hendricksons, Sulphurs, PMDs, BWOs) Mayfly NymphEphemerellidae (Hendricksons, Sulphurs, PMDs, BWOs) Mayfly Nymph View 3 PicturesThis 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.
