Despaxia augusta
autumn needlefly, smooth needlefly
Despaxia augusta is a species of rolled-winged stonefly in the family Leuctridae. It is commonly known as the autumn needlefly or smooth needlefly. The species was first described by Banks in 1907 under the basionym Leuctra augustus. It is distributed across western North America.
Illiesiella
Illiesiella is a genus of stoneflies in the family Leuctridae, commonly known as needleflies or rolled-winged stoneflies. These small, slender insects inhabit cool, clean freshwater environments. The genus was established to accommodate species previously placed in other leuctrid genera based on distinctive morphological characteristics. Members are found in the Holarctic region, with species distributed across Europe and parts of Asia.
Leuctra duplicata
Atlantic Needlefly
Leuctra duplicata, known as the Atlantic needlefly, is a rolled-winged stonefly in the family Leuctridae. It is a univoltine species with a life cycle adapted to intermittent streams. Adults emerge in mid-to-late May over a 3-4 week period. The species has been recorded from northeastern North America, with notable rarity in some parts of its range.
Leuctra ferruginea
Eastern Needlefly
Leuctra ferruginea, commonly known as the eastern needlefly, is a species of rolled-winged stonefly in the family Leuctridae. It is found in North America, with distribution records from the eastern and southeastern United States including Alabama, Connecticut, Delaware, Florida, Georgia, and Tennessee. As a member of the order Plecoptera, it is associated with aquatic habitats during its immature stages.
Leuctra laura
Hampshire needlefly
Leuctra laura, commonly known as the Hampshire needlefly, is a species of rolled-winged stonefly in the family Leuctridae. It was described by Hitchcock in 1969. The species is known from the northeastern United States, specifically New Hampshire and Vermont. As a member of Plecoptera, it is an aquatic insect whose immature stages develop in freshwater environments.
Leuctra truncata
Truncate Needlefly
Leuctra truncata, known as the truncate needlefly, is a species of rolled-winged stonefly in the family Leuctridae. The species was described by Claassen in 1923 and is distributed in eastern North America, with records from Connecticut, Maine, Newfoundland, New York, and Pennsylvania. As a member of Plecoptera, it has aquatic immature stages and terrestrial adults.
Leuctra variabilis
variable needlefly
Leuctra variabilis, known as the variable needlefly, is a species of rolled-winged stonefly in the family Leuctridae. It was described by Hanson in 1941. The species is found in eastern North America, with records from Maine, Massachusetts, Maryland, New Hampshire, and New Jersey.
Leuctrinae
Leuctrinae is a subfamily of stoneflies (order Plecoptera) within the family Leuctridae. Members of this group are small to medium-sized stoneflies commonly known as 'rolled-winged stoneflies' due to their distinctive wing posture at rest. The subfamily was established by Klapálek in 1905 and represents one of the major lineages within the Nemouroidea superfamily. Leuctrinae species are primarily associated with cool, clean running waters and are widely distributed across the Holarctic region.
Megaleuctra
needleflies
Megaleuctra is a genus of rolled-winged stoneflies in the family Leuctridae, established by Neave in 1934. The genus comprises approximately seven described species, including the Pacific needlefly (M. complicata). Species are distributed across western North America and Korea. The genus belongs to the subfamily Megaleuctrinae within the Leuctridae family.
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.
Paraleuctra sara
Appalachian needlefly
Paraleuctra sara, commonly known as the Appalachian needlefly, is a species of rolled-winged stonefly in the family Leuctridae. It was first described by Claassen in 1937. The species is found in eastern North America, with documented records from Alabama, Connecticut, Delaware, Georgia, and Indiana. As a member of the Leuctridae family, it belongs to a group of stoneflies characterized by their distinctive wing posture at rest.
Paraleuctra vershina
summit needlefly
Paraleuctra vershina, commonly known as the summit needlefly, is a species of rolled-winged stonefly in the family Leuctridae. It was described by Gaufin & Ricker in 1974. The species is distributed across western North America, with records from Alaska through western Canada to California and Colorado. As a member of the Leuctridae, it is characterized by wings that roll tightly around the body when at rest.
