Bolotoperla
winter stonefly
Bolotoperla is a genus of winter stoneflies in the family Taeniopterygidae, containing a single described species, B. rossi. The genus was established by Ricker & Ross in 1975. Winter stoneflies are active during cold months, distinguishing them from most other stonefly groups.
Bolotoperla rossi
Smoky Willowfly
Bolotoperla rossi is a species of stonefly in the family Taeniopterygidae, commonly known as the Smoky Willowfly. Originally described as Brachyptera rossi by Frison in 1942, it was later transferred to the genus Bolotoperla. This species belongs to the winter stonefly group, which are active during cold months when most other insects are dormant.
Nemouroidea
Rolled-winged Stoneflies, Forest Stoneflies, Winter Stoneflies
Nemouroidea is a superfamily of stoneflies (Plecoptera) within the suborder Arctoperlaria, comprising five families: Capniidae (winter stoneflies), Taeniopterygidae, Nemouridae, Notonemouridae, and Leuctridae. These stoneflies are predominantly found in freshwater habitats across the Northern Hemisphere. The group includes notable cold-adapted species such as snow flies that emerge during winter months.
Oemopteryx contorta
Dark Willowfly
Oemopteryx contorta, commonly known as the dark willowfly, is a species of winter stonefly in the family Taeniopterygidae. The species was described by Needham and Claassen in 1925. It is native to North America, with documented records from Alabama, Connecticut, Georgia, Kentucky, and Maine. As a member of the order Plecoptera, it belongs to a group of aquatic insects whose nymphal stages develop in freshwater environments.
Oemopteryx glacialis
Canadian willowfly
Oemopteryx glacialis, commonly known as the Canadian willowfly, is a winter stonefly species in the family Taeniopterygidae. It is one of several North American stoneflies adapted to cold-weather activity, with adults emerging during winter months when most other insects are inactive. The species has been recorded from the northeastern United States and adjacent Canada, including Connecticut, Michigan, Minnesota, New York, and Ontario.
Strophopteryx
mottled willowfly (for S. fasciata)
Strophopteryx is a genus of winter stoneflies comprising seven described species. Members are found in the Holarctic region, with records from North America and the Russian Far East. The genus belongs to the family Taeniopterygidae, a group characterized by adult emergence during cold months. Strophopteryx fasciata, the mottled willowfly, is the most well-known species and has been the subject of mitochondrial genome sequencing.
Taenionema californicum
California willowfly
Taenionema californicum, commonly known as the California willowfly, is a species of winter stonefly in the family Taeniopterygidae. It is native to North America, with documented presence in California. As a member of the order Plecoptera, it is associated with freshwater habitats. The species was first described by Needham and Claassen in 1925.
Taeniopteryx burksi
Eastern Willowfly
Taeniopteryx burksi, commonly known as the eastern willowfly, is a winter stonefly species in the family Taeniopterygidae. It was described by Ricker and Ross in 1968 and is distributed across eastern and central North America. The species belongs to a group of stoneflies adapted to cold-water environments and winter emergence patterns.
Taeniopteryx nivalis
boreal willowfly
Taeniopteryx nivalis, commonly known as the boreal willowfly, is a winter stonefly species in the family Taeniopterygidae. It is native to North America and has been recorded from multiple regions including Alberta, California, Connecticut, Delaware, and Idaho. As a member of the order Plecoptera, it belongs to a group of aquatic insects whose nymphs develop in freshwater habitats. The species was first described by Fitch in 1847.
