Ameletus (Brown Duns) Mayfly NymphAmeletus (Brown Duns) Mayfly Nymph View 7 PicturesI think this is a pretty 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.) Ameletus nymph. It's certainly a striking one.

Female Ameletus (Brown Duns) Mayfly SpinnerFemale Ameletus (Brown Duns) Mayfly Spinner View 13 PicturesI found this female already spent (Spent: The wing position of many aquatic insects when they fall on the water after mating. The wings of both sides lay flat on the water. The word may be used to describe insects with their wings in that position, as well as the position itself.) and nearly dead, laying in the surface film of a very tiny spring seep (inch-deep water) in the valley of a very small trout stream.
