Female Strophopteryx fasciata (Mottled Willowfly) Stonefly AdultFemale Strophopteryx fasciata (Mottled Willowfly) Stonefly Adult View 4 PicturesSeveral stoneflies of this species were the first adult insects I found in 2004 when I started this site. The hatch was sparse but lasted a good part of the day, and I noted a few good rises despite the early season cold. They ended up struggling on the water's surface fairly often.

Female Sweltsa (Sallflies) Stonefly AdultFemale Sweltsa (Sallflies) Stonefly Adult View 8 PicturesThese stoneflies--abundant during midday--seemed at first to be flying around with plain yellow bodies, but on closer inspection turn out to have striking, fiery red abdomens. This one keys out to albertensis, gaufini, or lambda, but the key (Baumann et al 1977) doesn't include all current species.

Megaleuctra stigmata (Little Black Needlefly) Stonefly AdultMegaleuctra stigmata (Little Black Needlefly) 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.
