Closeup insects from the South Fork Snoqualmie River
Male 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.
