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.

Male Calineuria californica (Golden Stone) Stonefly AdultMale Calineuria californica (Golden Stone) Stonefly Adult View 15 PicturesA few of these larger stoneflies were fluttering around the South Fork on an evening dominated by much smaller species.

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.

Edit: See forum comments for a likely correct identification.

1 Streamside Picture of Calineuria Stoneflies:

This Calineuria californica female was captured and placed in "bug jail," but was released when I saw it was loaded with eggs and about to drop them, and I could tell it was the same specis (albeit different gender) I photographed a few days ago.  In this picture: Stonefly Species Calineuria californica (Golden Stone). From Mystery Creek # 249 in Washington.
