As a microcaddisfly, it belongs to a group characterized by reduced larval cases and small adult size compared to other caddisflies.
Pachydiplax longipennis
Blue Dasher
The Blue Dasher (Pachydiplax longipennis) is a common and widely distributed dragonfly in the skimmer family Libellulidae. It is the sole species in its genus. Adults are characterized by a blue pruinose abdomen, particularly in males, and are known as "perchers" that hunt from stationary positions. Males exhibit pronounced territorial behavior at breeding and feeding sites, with social dominance hierarchies influencing dispersal patterns. The species occurs throughout North America and into the Caribbean.
Pacifastacus
Pacific Crayfish
Pacifastacus is a genus of freshwater crayfish endemic to western North America, comprising six species including the widespread signal crayfish (P. leniusculus) and two extinct species. The genus has gained significant conservation attention due to the invasive spread of P. leniusculus in Europe and Japan, where it transmits crayfish plague and displaces native species. Within its native range, several Pacifastacus species face population declines from habitat degradation and competition from invasive crayfishes.
Pacifastacus gambelli
Pacifastacus gambelli is a species of crayfish in the family Astacidae. The genus Pacifastacus is native to western North America, with species distributed across freshwater habitats in the Pacific Northwest and Rocky Mountain regions. P. gambelli is closely related to other Pacifastacus species including the widely studied signal crayfish (P. leniusculus), which has become a notorious invasive species in Europe. The species epithet 'gambelli' honors William Gambel, an American naturalist and explorer of the western United States in the 19th century.
Pacifastacus leniusculus
Signal Crayfish
The signal crayfish is a large North American freshwater crayfish introduced to Europe in the 1960s to replace declining native fisheries. It has become one of the most ecologically impactful invasive decapods in Europe, outcompeting native crayfish and serving as a carrier of crayfish plague (Aphanomyces astaci). The species establishes self-sustaining populations rapidly, with six age cohorts documented within a few years of introduction. It shows sex- and size-specific coloration patterns, with males displaying more saturated and brighter ventral claw surfaces than females, suggesting a role in intraspecific communication.

leuckartii
Podon leuckartii is a small predatory crustacean in the family Podonidae, order Onychopoda. It belongs to the branchiopod group characterized by paired swimming appendages and a bivalved carapace. The species was originally described under the genus Pleopis. Like other onychopods, it is a holoplanktonic predator in freshwater and brackish aquatic systems.
Polycentropodidae
Tube Maker Caddisflies, Trumpet-net Caddisflies
Polycentropodidae is a family of caddisflies (Trichoptera) commonly known as tube makers or trumpet-net caddisflies. The family contains at least 33 genera and over 720 described species globally. Larvae construct distinctive silken retreats—short flattened tubes in rock hollows or slender tubular structures among aquatic vegetation—often surrounded by silken threads that function as prey detection devices. The family exhibits a disjunct distribution pattern in some regions, with species found in both tropical and temperate zones.
Polypedilum
Polypedilum is a genus of non-biting midges in the family Chironomidae, subfamily Chironominae. It is probably the most species-rich genus among all chironomid midges. Larvae are frequently abundant in lentic freshwater habitats, with documented densities reaching 1200 larvae per square meter in eutrophic ponds. The genus comprises multiple subgenera including Cerobregma, Pentapedilum, Polypedilum, Probolum, Tripodura, and Uresipedilum.
Polypedilum fallax
Polypedilum fallax is a species of non-biting midge in the family Chironomidae, originally described by Johannsen in 1905. The species is part of the large and diverse genus Polypedilum, which contains numerous species often difficult to distinguish morphologically. Records of this species exist from Norway and Sweden, though some Swedish records are marked as doubtful. The species is known from 145 observations on iNaturalist, suggesting it is moderately documented but not extensively studied.
Polypedilum illinoense
Polypedilum illinoense is a species of non-biting midge in the family Chironomidae, originally described by Malloch in 1915 from Illinois. As a member of the large genus Polypedilum, it is part of a diverse group of aquatic insects whose larvae inhabit freshwater environments. The species is known from observational records across North America, though detailed biological studies remain limited. Adults are small, delicate flies that do not feed, while larvae are aquatic detritivores.
Polypedilum trigonus
Polypedilum trigonus is a species of non-biting midge in the family Chironomidae, order Diptera. As a member of the genus Polypedilum, it belongs to a diverse group of aquatic insects whose larvae are commonly found in various freshwater habitats. The species epithet "trigonus" (Greek for "triangular") likely refers to a morphological feature of the adult or larva. Chironomid larvae are important components of aquatic food webs and are widely used as bioindicators of water quality.
Polyphemidae
Polyphemidae is a family of predatory water fleas (Branchiopoda) containing the single genus Polyphemus with two recognized species: P. pediculus and P. exiguus. Members are characterized by large, raptorial antennae used for capturing prey and a reduced carapace that leaves the body exposed. P. pediculus has a broad Holarctic distribution in freshwater and brackish habitats, while P. exiguus is restricted to the Caspian Sea. Cryptic species have been identified within P. pediculus due to allopatric speciation.
Potamyia flava
Yellow Net-spinning Caddisfly
Potamyia flava is a species of net-spinning caddisfly in the family Hydropsychidae, distributed across North America. As a member of the Hydropsychidae, larvae construct fixed capture nets to filter food particles from flowing water. Adults are recognized by their yellow coloration, which distinguishes them from related species. The species has been well-documented through citizen science observations, with over 2,000 records on iNaturalist.
Procambarus
crayfish, crawfish, crawdad
Procambarus is a genus of freshwater crayfish in the family Cambaridae, native to North and Central America. The genus contains approximately 160 species in 16 subgenera, making it one of the most species-rich crayfish genera. It includes both widespread surface-dwelling species and numerous troglobitic (cave-dwelling) species. The marbled crayfish (marmorkrebs), a parthenogenetic form, is also classified within this genus. Several species, particularly P. clarkii (red swamp crayfish), have been introduced globally and are recognized as invasive species with significant ecological and economic impacts.
Procambarus acutus
White River Crayfish
Procambarus acutus, commonly known as the white river crayfish, is a freshwater crayfish species in the family Cambaridae native to eastern North America. The species exhibits a disjunct native distribution spanning from the Atlantic Slope to the Gulf of Mexico drainages. It has been introduced to multiple regions outside its native range, including parts of Europe and Africa, where it poses potential ecological and economic risks. Two subspecies are recognized: P. a. acutus and P. a. cuevachicae.
Procambarus acutus acutus
White River crayfish, eastern white river crayfish
Procambarus acutus acutus is a subspecies of freshwater crayfish native to the southeastern United States. It has been introduced to Ontario, Canada, where established populations now exist in the Severn Sound region and Oakbank Pond near Toronto. The species forms stable dominance hierarchies and exhibits status recognition between conspecifics. It is capable of causing economic damage to fisheries through scavenging behavior.
Procladius
Procladius is a genus of non-biting midges in the family Chironomidae, subfamily Tanypodinae. Larvae are predatory and inhabit freshwater benthic environments including lakes, reservoirs, and wetlands. The genus exhibits considerable species diversity with over 50 described species distributed across the Holarctic and other regions. Some species have adapted to fluctuating water levels in reservoir environments.
Procladius bellus
Procladius bellus is a non-biting midge in the family Chironomidae, first described by Loew in 1866. It inhabits freshwater systems, particularly reservoirs with fluctuating water levels. Research in Laurel Creek Reservoir, Ontario, documented its ability to survive winter drawdown periods and complete three generations annually under favorable conditions.
