Allocapnia rickeri
Midwest Snowfly
Allocapnia rickeri is a small winter stonefly in the family Capniidae, commonly known as the Midwest Snowfly. It is one of numerous small, dark stoneflies in the genus Allocapnia that emerge during cold months when few other insects are active. The species has been documented across the central and eastern United States. Like other capniids, it is associated with clean, cold streams and is an important indicator of water quality.

Anisocentropus
Anisocentropus is a cosmopolitan genus of caddisflies (Trichoptera: Calamoceratidae) comprising over 60 described species distributed across Oriental, Australasian, Afrotropical, Neotropical, Nearctic, and East Palearctic regions. Larvae are case-building detritivores that construct portable shelters from leaf pieces or wood fragments, inhabiting both lotic and lentic freshwater environments depending on species. The genus exhibits notable variation in habitat preference, with some species strictly adapted to standing water while others occupy running water or both environments.

Calamoceratidae
Calamoceratidae is a family of caddisflies comprising approximately 9 genera and at least 120 described species. The family is distributed across tropical and temperate regions worldwide, with notable diversity in the Neotropics. Larvae are aquatic and construct distinctive cases from plant material. The genus Phylloicus is particularly species-rich in the New World, with 66 described species.

Gammarus
scuds, freshwater shrimp, sideswimmers
Gammarus is a genus of amphipod crustaceans in the family Gammaridae, containing over 200 described species and representing one of the most species-rich crustacean genera. Species occupy diverse aquatic habitats ranging from purely freshwater to estuarine and marine environments, with salinity tolerance varying markedly among species. The genus is widely distributed throughout the Holarctic region, with additional species extending into tropical Southeast Asia. Gammarus species serve important ecological functions as shredders and predators in aquatic food webs.

Glyphopsyche
Glyphopsyche is a genus of northern caddisflies (Trichoptera: Limnephilidae) established by Banks in 1904. The genus contains at least three described species: G. irrorata, G. missouri, and G. sequatchie. Glyphopsyche irrorata has been documented with an unusual life history strategy among caddisflies: overwintering as an adult rather than in the larval stage.

Limnephilus
caddisfly
Limnephilus is the most diverse genus in the family Limnephilidae, containing over 180 described species with broad ecological tolerances and a primarily Holarctic distribution. Species inhabit diverse freshwater habitats including lakes, ponds, slow-moving streams, and high-altitude streams, with some extending to salt marshes and desert environments. Several species are of conservation concern in North America. The genus has been extensively studied as a bioindicator for aquatic pollution and as a model for understanding predator-prey interactions and case-building behavior.

Nectopsyche
White Miller Caddisflies, White Millers
Nectopsyche is a genus of caddisflies in the family Leptoceridae, commonly known as white millers. The genus contains at least 70 described species distributed across the Americas, with records from North America through the tropical Andes. Species occupy diverse freshwater habitats ranging from lentic (still-water) environments to lotic (flowing) highland streams. Several species have been studied as bioindicators of aquatic pollution due to their sensitivity to pesticides and heavy metals.

Philocasca
Philocasca is a genus of caddisflies (Trichoptera: Limnephilidae) established by Ross in 1941, containing species native to western North America. The genus has undergone taxonomic revision, with three species (P. alba, P. thor, and P. antennata) transferred to the new genus Montiphylax based on morphological distinctions in wing patterns, genitalia structure, and larval setae. Remaining Philocasca species include P. banksi, P. demita, P. oron, and P. rivularis. The genus exhibits notable ecological diversity, including both aquatic and terrestrial larval habits.

Phryganea
giant caddisfly, giant caddisflies
Phryganea is a genus of large caddisflies in the family Phryganeidae, commonly known as giant caddisflies. The genus contains approximately 25–30 described species distributed across the northern hemisphere, with particularly high diversity in Europe and Asia. Larvae construct portable cases from plant material and are among the most primitive of the tube-case-building caddisflies. Adults are notable for their relatively large size compared to other caddisfly genera.

Phylloicus aeneus
Phylloicus aeneus is a caddisfly species in the family Calamoceratidae, first described by Hagen in 1861. It is known from Central America and is part of a genus of caddisflies whose larvae construct distinctive leaf-case shelters. The species belongs to an order of aquatic insects with high ecological importance in freshwater ecosystems.

Pycnopsyche
northern caddisflies
Pycnopsyche is a genus of northern caddisflies comprising approximately 17 described species. Larvae are aquatic shredders inhabiting leaf packs in temperate streams, where they construct portable cases from leaf material. The genus exhibits temporal niche partitioning among sympatric species, with differences in case materials, habitat preferences, and adult flight periods reducing interspecific competition.

Pycnopsyche gentilis
caddisfly
Pycnopsyche gentilis is a northern caddisfly in the family Limnephilidae. Larvae are shredders that inhabit allochthonous organic materials in freshwater streams, where they feed on leaf litter colonized by aquatic fungi. The species is contemporaneous with congeneric P. luculenta, though larvae differ in case materials and habitat preferences. Adult males exhibit temporal partitioning of flight activity, with distinct peak arrival times at light sources when active on the same night as congeners.

Sericostomatidae
Bushtailed Caddisflies
Sericostomatidae is a family of caddisflies (Trichoptera) commonly known as bushtailed caddisflies. The family comprises approximately 19 genera and at least 90 described species. Larvae construct portable cases using silk and environmental materials. The family has a global distribution with notable diversity in the Palearctic region, including endemic species in the Balkans, Iberian Peninsula, and Madagascar.

Tortopus
Tortopus is a genus of burrowing mayflies in the family Polymitarcyidae, restricted to six species based on cladistic revision: T. igaranus, T. circumfluus, T. harrisi, T. zottai, T. bellus, and T. arenales. The genus is characterized by distinctive morphological synapomorphies including female parastyli receptors with long anterior furrows, entirely flattened penes, and nymphs bearing two subapical tubercles on mandibular tusks. Nymphs construct U-shaped tunnels in clay banks, a behavior that renders them difficult to sample with standard aquatic survey methods.

Yoraperla
roach-like stoneflies
Yoraperla is a genus of stoneflies in the family Peltoperlidae, commonly known as "roach-like stoneflies" due to their resemblance to cockroaches. The genus contains eight described species distributed across North America and Asia. Yoraperla was established by Ricker in 1952 and is classified within the subfamily Peltoperlinae.

Zapada
forestflies, spring stoneflies, little brown stoneflies
Zapada is a genus of small spring stoneflies in the family Nemouridae, commonly known as forestflies or little brown stoneflies. The genus contains at least 10 described species distributed across western North America, from Alaska and the Rocky Mountains to California. Adults are 5–8 mm in body length and emerge in early spring, often February through April depending on elevation and species. Nymphs are aquatic shredders that process leaf litter and other organic matter in cold, well-oxygenated streams.

Zapada cinctipes
Common Forestfly
Zapada cinctipes, the common forestfly, is a small spring stonefly in the family Nemouridae. Adults measure 5–8 mm in body length and emerge primarily from mid-March to mid-April, with some appearing as early as late February. The species is univoltine, completing one generation per year. Nymphs are aquatic shredders that feed on decaying leaf material in flowing waters.

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.
