Taeniopteryx nivalis (Early Black Stonefly) Stonefly NymphTaeniopteryx nivalis (Early Black Stonefly) Stonefly Nymph View 2 PicturesI found this nymph wriggling in the surface film during a hatch of related Strophopteryx adults. This nymph died in transport so it's not alive in the photos, but it's pretty close to its live colors.

Taenionema (Willowflies) Stonefly NymphTaenionema (Willowflies) Stonefly Nymph View 11 PicturesThis specimen was the only one of its kind in my kick net sample from this small creek. At first I thought it was Nemouridae, but it's not. Unfortunately, there is no species key available for Taenionema nymphs. Potential species found in Washington include nigripenne, oregonense, pacificum, and pallidum.

Female Strophopteryx fasciata (Mottled Willowfly) Stonefly AdultFemale Strophopteryx fasciata (Mottled Willowfly) Stonefly Adult View 5 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.
