Cosumnoperla hypocrena
Cosumnes Spring Stonefly
Cosumnoperla hypocrena is a species of spring stonefly in the family Perlodidae, described from California in 1987. The genus Cosumnoperla contains species associated with spring-fed habitats. As a member of the subfamily Isoperlinae, it shares characteristics with other western North American perlodids. The specific epithet refers to the type locality near the Cosumnes River.
Ostrocerca albidipennis
white-tailed forestfly, whitetailed forestfly
Ostrocerca albidipennis, commonly called the white-tailed forestfly, is a species of spring stonefly in the family Nemouridae. It was originally described as Nemoura albidipennis by Walker in 1852. The species is found in eastern North America, with records from Connecticut, Maine, Massachusetts, Michigan, and Maryland. As a member of the Nemouridae family, it belongs to the group of small stoneflies commonly known as forestflies.
Ostrocerca complexa
Notched Forestfly
Ostrocerca complexa, commonly known as the notched forestfly, is a species of spring stonefly in the family Nemouridae. First described by Claassen in 1937 as Nemoura complexa, it is now placed in the genus Ostrocerca. It occurs in eastern North America, with documented records from Connecticut, Maine, Massachusetts, New Brunswick, and Nova Scotia.
Ostrocerca dimicki
Hooked Forestfly
Ostrocerca dimicki, commonly known as the hooked forestfly, is a species of spring stonefly in the family Nemouridae. It belongs to the order Plecoptera, a group of aquatic insects whose nymphs inhabit cold, clean streams. The species was described by Frison in 1936. It is recorded from the Pacific Northwest region of North America.
Ostrocerca prolongata
Bent Forestfly
Ostrocerca prolongata, commonly known as the bent forestfly, is a species of spring stonefly in the family Nemouridae. It was described by Claassen in 1923. The species is found in eastern North America, with records from the northeastern United States and adjacent Canada. Like other members of Nemouridae, it is associated with forested stream habitats.
Ostrocerca truncata
Truncate Forestfly
Ostrocerca truncata, commonly known as the truncate forestfly, is a species of spring stonefly in the family Nemouridae. Originally described as Nemoura truncata by Claassen in 1923, it is one of approximately 50 species in the genus Ostrocerca. The species is found in eastern North America, with records from Connecticut, Indiana, Kentucky, Maine, Massachusetts, and other states. Like other Nemouridae, it is associated with cool, clean streams and emerges in spring.
Paranemoura
Paranemoura is a genus of spring stoneflies in the family Nemouridae, established by Needham & Claassen in 1925. The genus contains at least two described species: P. claasseni (1996) and P. perfecta (1852), the latter commonly known as the spotted forestfly. As members of the order Plecoptera, these insects are aquatic during their immature stages and terrestrial as adults.
Paranemoura perfecta
spotted forestfly
Paranemoura perfecta, commonly known as the spotted forestfly, is a species of spring stonefly in the family Nemouridae. It was first described by Walker in 1852 under the basionym Nemoura perfecta. The species is found in eastern North America, with documented records from Connecticut, Maine, Massachusetts, Michigan, and Maryland. As a member of the Nemouridae, it belongs to the group of spring stoneflies characterized by small size and cold-water habitat associations.
Prostoia
Prostoia is a genus of spring stoneflies in the family Nemouridae, established by Ricker in 1952. The genus contains five described species distributed across North America. Two species have common names: Prostoia completa (central forestfly) and Prostoia similis (longhorn forestfly). Members of this genus are part of the Nemourinae subfamily within the Nemouridae family of stoneflies.
Prostoia completa
central forestfly
Prostoia completa, known as the central forestfly, is a species of spring stonefly in the family Nemouridae. It has been recorded from scattered localities in the eastern and central United States. As a member of the Nemouridae, it belongs to a family of small, cold-adapted stoneflies often associated with forested streams. The species was originally described as Nemoura completa by Walker in 1852.
Prostoia similis
Longhorn Forestfly
Prostoia similis, commonly known as the longhorn forestfly, is a species of spring stonefly in the family Nemouridae. It is found in North America, with records from states including Connecticut, Delaware, Illinois, Indiana, and Kentucky. As a member of the order Plecoptera, it belongs to an ancient group of aquatic insects whose nymphs typically inhabit cool, clean streams.
Shipsa
spring stoneflies
Shipsa is a monotypic genus of spring stoneflies in the family Nemouridae, containing the single species Shipsa rotunda. The genus was described by Ricker in 1952. The sole species has an extensive Nearctic distribution across northern North America, with records from multiple Canadian provinces and US states. Morphological studies indicate little variation in reproductive structures across its wide geographic range.
Soyedina washingtoni
vernal forestfly
Soyedina washingtoni, commonly known as the vernal forestfly, is a species of spring stonefly in the family Nemouridae. It was first described by Claassen in 1923 under the basionym Nemoura washingtoni. As a member of the order Plecoptera, it belongs to a group of aquatic insects whose nymphal stages develop in freshwater habitats.
Zapada columbiana
Columbian forestfly
Zapada columbiana is a species of spring stonefly in the family Nemouridae, commonly known as the Columbian forestfly. It is a small stonefly with a life cycle spanning 2-3 years in Rocky Mountain streams. The species is notable for retaining cervical gills into adulthood, a diagnostic feature of the genus. Nymphs are shredders that feed on moss and detritus, playing a significant role in stream ecosystem nutrient cycling.
