Female Suwallia pallidula (Sallfly) Stonefly AdultFemale Suwallia pallidula (Sallfly) Stonefly Adult View 6 PicturesI didn't key this one out under the microscope, but I just keyed a similar one from Montana and this one matches the macroscopic appearance closely enough that I'm guessing it's the same thing.

Isoperla quinquepunctata (Little Yellow Stonefly) Little Yellow Stonefly NymphIsoperla quinquepunctata (Little Yellow Stonefly) Stonefly Nymph View 2 PicturesSize - (excluding tails) - 10 mm
Status at time of photo - preserved but no discernible color change as specimen was captured only a few days earlier.
Key characters - unique pattern on dorsal (Dorsal: Top.) head and thorax (Thorax: The thorax is the middle part of an insect's body, in between the abdomen and the head, and to which the legs and wings are attached.); dark medial (Medial: Toward the middle of the body.) terga (Tergum: the dorsal part of an abdominal segment or segments (terga). Also used to describe the entire abdominal dorsum or the thoracic dorsal segments of Odonata.) stripe between two paler stripes

This species is very common in west slope north Sierra watersheds. Richard W. Baumann & Boris C. Kondratieff did a study on the same section and at the same time of year (APRIL 25-29, 2010) where this specimen was taken. No other species of Isoperla were reported from this location and quinquepunctata was very abundant. Their hatches can be very heavy some Springs.
