Chloroperlidae
Green Stoneflies, Green Sallies, Yellow Sallies, Yellow Sallflies
Chloroperlidae is a family of stoneflies comprising over 200 species across 22 genera, commonly known as green stoneflies for their characteristic yellowish-green to green coloration. Adults range from 6–20 mm in body length and are distinguished by relatively short cerci, slender labial palps, and wings pads that remain parallel to the body midline. The family exhibits hemimetabolous development with egg, nymph, and adult stages but no pupal stage. Nymphs are aquatic inhabitants of cold, clean streams and rivers across five continents, where their sensitivity to pollutants makes them important bioindicators of water quality. Adults are primarily terrestrial, dwelling in riparian vegetation near water bodies with a brief lifespan focused on reproduction.
Chloroperlinae
Chloroperlinae is a subfamily of stoneflies within the family Chloroperlidae, established by Okamoto in 1912. Members are commonly known as green stoneflies due to their characteristic coloration. The subfamily occurs across multiple continents in cold freshwater habitats. Adults emerge from aquatic environments to inhabit riparian zones.
Haploperla brevis
Least Sallfly
Haploperla brevis, commonly known as the least sallfly, is a species of green stonefly in the family Chloroperlidae. It is a small plecopteran insect found in North America, with distribution records from Alberta, Alabama, Arkansas, British Columbia, and Connecticut. The species was first described by Nathan Banks in 1895.
Paraperla
green stoneflies
Paraperla is a genus of green stoneflies in the family Chloroperlidae, established by Banks in 1906. It contains at least two described species: P. frontalis (the hyporheic sallfly) and P. wilsoni. The genus belongs to the subfamily Paraperlinae and is characterized by its association with subterranean or hyporheic aquatic habitats. These stoneflies are part of the Arctoperlaria, a suborder of Plecoptera found primarily in the Northern Hemisphere.
Suwallia marginata
York sallfly
Suwallia marginata, commonly known as the York sallfly, is a species of green stonefly in the family Chloroperlidae. It is native to North America and has been recorded from several eastern and northeastern localities including Maine, Massachusetts, Maryland, Georgia, and Labrador. As a member of the Chloroperlidae, it belongs to a family commonly referred to as green stoneflies or sallflies.
Sweltsa borealis
Boreal Sallfly
Sweltsa borealis, known as the boreal sallfly, is a species of green stonefly in the family Chloroperlidae. It is native to North America with documented records from Alaska, Alberta, British Columbia, California, and Colorado. As a member of the Chloroperlidae family, it belongs to a group commonly referred to as green stoneflies or sallflies. The species was first described by Banks in 1895.
Sweltsa lateralis
Curved Sallfly
Sweltsa lateralis, commonly known as the curved sallfly, is a species of green stonefly in the family Chloroperlidae. It was first described by Nathan Banks in 1911 under the basionym Alloperla lateralis. The species is found in eastern North America, with records from Connecticut, Georgia, Maine, Massachusetts, Maryland, and other states. Like other members of Chloroperlidae, it is associated with clean, cool freshwater habitats.
Sweltsa naica
Northeastern Sallfly
Sweltsa naica, commonly known as the northeastern sallfly, is a species of green stonefly in the family Chloroperlidae. It is known from a restricted distribution in northeastern North America. The species was described by Provancher in 1876. As a member of Chloroperlidae, it belongs to a family commonly referred to as green stoneflies or sallflies.
Sweltsa onkos
Ontario Sallfly
Sweltsa onkos, commonly known as the Ontario sallfly, is a species of green stonefly in the family Chloroperlidae. It belongs to the order Plecoptera, an ancient group of aquatic insects. The species has been documented in northeastern North America.
