Female Claassenia sabulosa (Golden Stone) Stonefly Adult
View 3 PicturesI think this is one of the most poorly understood of the golden stoneflies. It is rare to see any articles about it or fishing the hatch. It emerges late in summer usually on medium to large rivers.The adults are quite secretive but it is something to see the adults run across the water surface. These guys can really run. The males have short wings.The females are up to 1 1/4 inch long rivaling the salmonfly as the largest adult stonefly in the west.The adults are not real golden in color, especially the females which are more of an off yellow to off white abdomen. In handling the adults it is obvious that they shun direct sunlight. I find them by turning over rocks close to the water's edge.

Male Claassenia sabulosa (Golden Stone) Stonefly Adult
View 2 PicturesThe males have these abbreviated wings. I doubt they can fly but they can run faster than any stonefly I have seen. The also have an interesting habit of jumping.
