Female Claassenia sabulosa (Golden Stone) Stonefly AdultFemale 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.

Megaleuctra stigmata (Tiny Winter Black) Stonefly AdultMegaleuctra stigmata (Tiny Winter Black) Stonefly Adult View 3 PicturesThis is one of rarest stoneflies in western Montana. It is a bit unusual that it is fairly abundant in a handful of streams that empty into the east side of Flathead Lake. A very beautiful bug.

Pteronarcys californica (Giant Salmonfly) Stonefly NymphPteronarcys californica (Giant Salmonfly) Stonefly Nymph View 2 PicturesHere are two size classes of Pteronarcys nymphs. These probably represent two different generations. The largest will probably emerge next spring and the other in two years. There is probably another generation, smaller, I did not collect. In a Canadian study they discovered Pteronarcys eggs do not all hatch simultaneously but hatch for a period of nearly two years, making their egg/nymphal life 5 years. The other photo is of a curled nymph, a typical response to disturbance.

Male Claassenia sabulosa (Golden Stone) Stonefly AdultMale 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.
