Male Rhithrogena undulata (Small Western Red Quill) Mayfly SpinnerMale Rhithrogena undulata (Small Western Red Quill) Mayfly Spinner View 13 PicturesThis male was collected at the same time as this female and is likely the same species.

It keys pretty clearly to Rhithrogena undulata using the key in Traver 1935, although the size is larger than expected for that species in that source.

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.
