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 Strophopteryx fasciata (Mottled Willowfly) Stonefly AdultFemale Strophopteryx fasciata (Mottled Willowfly) Stonefly Adult View 4 PicturesSeveral stoneflies of this species were the first adult insects I found in 2004 when I started this site. The hatch was sparse but lasted a good part of the day, and I noted a few good rises despite the early season cold. They ended up struggling on the water's surface fairly often.
