Female 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. Male Calineuria californica (Golden Stone) Stonefly Adult

This one has been difficult to identify. I can't spot any of the gill remnants characteristic of Perlidae, but the wing venation (Venation: The pattern in which the veins on the wings of an insect are arranged. It is usually one of the most useful identifying characteristics.) seems to point in that direction. I tried keying it out as Perlodidae but arrived at Isoperla, every western species of which has significantly smaller bodies than this one.
