Ammopelmatus
Jerusalem crickets, potato bugs, North American Jerusalem Crickets
Ammopelmatus is a genus of large, flightless crickets in the family Stenopelmatidae, commonly known as Jerusalem crickets or potato bugs. The genus was erected by Tinkham in 1965 and underwent massive taxonomic revision in 2025, expanding from 12 recognized species to 117 valid species across the western United States and northwestern Mexico. These insects are among the largest in western North America, with some adults exceeding 12 grams. The genus exhibits exceptional species diversity concentrated in Southern and Central California, with most species having limited geographic distributions.
Capniidae
small winter stoneflies, winter stoneflies
Capniidae, the small winter stoneflies, is one of the largest families in the order Plecoptera, comprising approximately 300 species distributed throughout the Holarctic region. Adults are active during winter months, often observed on snow-covered stream banks when most other insects are dormant. The family exhibits notable adaptations to cold environments, including antifreeze compounds and winglessness in some species, which has led to high endemism and restricted distributions. Their closest relatives are the rolled-winged stoneflies (Leuctridae).
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.
Isogenoides hansoni
Appalachian springfly
Isogenoides hansoni, known as the Appalachian springfly, is a species of stonefly in the family Perlodidae. It has been documented in northeastern North America, including the northeastern United States and southeastern Canada. The species communicates through vibrational drumming, a behavior shared with other members of its genus. It was first described by Ricker in 1952.
Isoperlinae
Stripetail Stoneflies, Springflies
Isoperlinae is a subfamily of stoneflies in the family Perlodidae, distributed across the Palaearctic and Nearctic regions. Members are commonly known as stripetails or springflies. The subfamily includes approximately 12 genera, with Isoperla being the most speciose and well-known. These stoneflies are aquatic insects whose nymphs inhabit running waters.
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.
Meconema thalassinum
Oak Bush-cricket, Drumming Katydid
Meconema thalassinum is a small, pale green arboreal bush-cricket in the family Tettigoniidae. Native to Europe, it is the only native arboreal Orthopteran species in the UK and has been introduced to North America within the last 75 years. Males attract females through a unique non-stridulatory method: drumming their hind limbs against leaves to produce vibrations. Unlike most bush-crickets, this species is carnivorous, feeding on invertebrate prey.
Perlodidae
perlodid stoneflies, stripetails, springflies, Stripetail and Springfly Stoneflies
Perlodidae is a family of stoneflies comprising at least 50 genera and over 350 species, with fossil records extending to the Triassic. Adults are commonly known as stripetails or springflies and typically emerge from April to June. The family is characterized by larvae with flattened bodies, patterned heads and thoraces, long tails, and divergent hind wing pads that lack the branching thoracic gills found in similar stonefly families.
Pteronarcella badia
Least Salmonfly
Pteronarcella badia, commonly known as the least salmonfly, is a stonefly species in the family Pteronarcyidae found in western North America. It is one of two species in the genus Pteronarcella. The species occupies mid-elevation mountain streams and exhibits complex population genetic structure with six deeply divergent clades across its range. Adults are capable of overland flight, which serves as an important dispersal mechanism between drainage systems.
