Female Hesperoperla pacifica (Golden Stone) Stonefly AdultFemale Hesperoperla pacifica (Golden Stone) Stonefly Adult View 13 PicturesMy blurry photo at first makes it look like there might be a distinct notch in the subgenital plate of this specimen, but that's not the case -- just a poor photo. That's important to the ID.

Tallaperla (Roachflies) Stonefly NymphTallaperla (Roachflies) Stonefly Nymph View 6 PicturesThis is the first specimen of the Peltoperlidae stonefly family that I've collected. It's very small and probably an 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.), but I'm not choosy about new bugs.

Female Calineuria californica (Golden Stone) Stonefly AdultFemale Calineuria californica (Golden Stone) Stonefly Adult View 17 PicturesI caught this female in the vegetation on a trail about 50 feet above the stream. The coloration on its head differs from that of a male I collected recently on a nearby river, and from another female I collected on the same river. But it still keys out confidently to Calineuria, and californica is the only species of that genus in the area.

Female Amphinemura (Tiny Winter Blacks) Stonefly AdultFemale Amphinemura (Tiny Winter Blacks) Stonefly Adult View 5 PicturesA few of these tiny stoneflies were among the only species of aquatic insect adults in the air on this particular afternoon, with most of the action coming from a species of Epeorus mayfly. I somehow forgot to photograph this one on the usual ruler, but I recall it was very, very small, with an abdomen no more than 1mm in girth and the body, not counting the wings, probably just 5-7mm long.
