Achorotile distincta
Achorotile distincta is a species of planthopper in the family Delphacidae, first described by Scudder in 1963. It belongs to a genus of small, delicate delphacid planthoppers characterized by reduced wing venation and distinctive genitalia structures. The species is known from western and northern regions of North America, with records from Canada extending into Alaska. Like other delphacids, it likely inhabits moist grassland and marsh habitats where host grasses occur.
Amphicyrta dentipes
Amphicyrta dentipes is a species of pill beetle in the family Byrrhidae. It belongs to a genus of small, compact beetles adapted to moist habitats. The species epithet "dentipes" refers to toothed feet, a characteristic feature of this group. Very little specific information has been published about this particular species.
Chortophaga
green-striped grasshopper, band-winged grasshopper
Chortophaga is a genus of North American band-winged grasshoppers in the family Acrididae, tribe Chortophagini. The genus contains at least four recognized species, with C. viridifasciata (northern green-striped grasshopper) being the most widely distributed and best studied. Members are characterized by their banded hindwings and preference for moist grassland habitats. The genus ranges from Canada through the United States and into Central America and the Caribbean.
Corticaria impressa
minute brown scavenger beetle
Corticaria impressa is a species of minute brown scavenger beetle in the family Latridiidae. It is native to Europe and has been recorded in parts of North America including New Brunswick and Nova Scotia, Canada. The species belongs to a group of small beetles commonly known as "plaster beetles" or "minute brown scavenger beetles" due to their association with damp, decaying organic matter and their diminutive size.
Eulimnichus
minute marsh-loving beetles
Eulimnichus is a genus of minute marsh-loving beetles in the family Limnichidae, established by Casey in 1889. The genus contains over 30 described species distributed across North, Central, and South America. Members are small beetles associated with moist or marshy habitats. The genus is part of the subfamily Limnichinae within the dryopoid beetle lineage.
Hilaira herniosa
Hilaira herniosa is a species of sheet-web weaving spider in the family Linyphiidae, one of the largest families of spiders. First described by Tamerlan Thorell in 1875 under the name Erigone herniosa, this small-bodied spider has a documented distribution spanning the Holarctic region, including northern Europe, Asia, and North America. The species inhabits moist, cool environments typical of many linyphiid spiders. Specific details regarding its biology and ecology remain limited in published literature.
Macrosaldula monae
Macrosaldula monae is a species of shore bug in the family Saldidae, described by Drake in 1952. It belongs to the infraorder Leptopodomorpha, a group of predatory true bugs associated with moist habitats. The species has been documented in North America, though detailed biological information remains limited.
Neolimnophila placida
Placid Crane Fly
Neolimnophila placida is a crane fly species in the family Limoniidae, subfamily Chioneinae. It is widely distributed across the Holarctic region, occurring in both the Nearctic and Palaearctic realms. The species has been documented from northern North America through much of Europe and across northern Asia to Japan. Like other limoniid crane flies, it is associated with moist habitats where larvae develop in decaying organic matter.
Nomotettix cristatus
crested pygmy grasshopper, crested grouse locust, northern crested grouse locust
Nomotettix cristatus is a small pygmy grasshopper in the family Tetrigidae, commonly known as the crested pygmy grasshopper or crested grouse locust. It is one of approximately 35 Nearctic species of Tetrigidae. The species exhibits three recognized subspecies with distinct geographic distributions across North America. Like other members of its family, it is characterized by an elongated pronotum that extends over the abdomen, a trait distinguishing pygmy grasshoppers from typical grasshoppers in Acrididae.

collaris
Nyholmia collaris is a species of marsh beetle in the family Scirtidae. It has been recorded across eastern Canada and is present in North America generally. The species was originally described by Guérin-Méneville in 1843 and is currently classified under the genus Nyholmia, though it was previously placed in Cyphon.
Panorpa anomala
common scorpionfly
Panorpa anomala is a species of scorpionfly in the family Panorpidae, first described by Carpenter in 1931. It occurs in North America, where it inhabits moist wooded environments. As a member of the genus Panorpa, it shares the characteristic elongated rostrum and upturned male genitalia that give scorpionflies their common name.
Scaphinotus andrewsii
Andrew's Snail-eating Beetle
Scaphinotus andrewsii is a ground beetle in the family Carabidae, commonly known as Andrew's Snail-eating Beetle. It is found in North America, where it inhabits moist areas and preys primarily on snails. The species exhibits a dark, black exoskeleton with a somewhat elongated head and thorax. Seven subspecies are recognized, distributed across the Appalachian region from Pennsylvania south to Georgia.
Scaphinotus infletus
Forgotten Snail-eating Beetle
Scaphinotus infletus, commonly known as the forgotten snail-eating beetle, is a species of ground beetle in the family Carabidae. It is endemic to North America, with known occurrence in Arkansas. The species is characterized by brachypterous (short-winged) adults and inhabits moist, shaded environments. As a member of the genus Scaphinotus, it is presumed to be a molluscivore, feeding on snails and slugs.
Tetrix
ground-hoppers, pygmy grasshoppers
Tetrix is a genus of ground-hoppers (family Tetrigidae) comprising at least 180 described species of minute jumping insects. These pygmy grasshoppers are characterized by their small size (typically around 1 cm), enlarged pronotum that often extends over the abdomen, and association with moist habitats near water. The genus has a Holarctic distribution with particular research focus on European and North American species, though this represents only a small fraction of global diversity. Some Tetrix species exhibit incomplete reproductive isolation where sympatric, with documented heterospecific courtship and mating between closely related species.
Tetrix subulata
Slender Ground-hopper, Slender Groundhopper, Awl-shaped Pygmy Grasshopper, Slender Grouse Locust
Tetrix subulata is a small groundhopper (family Tetrigidae) with a Holarctic distribution spanning the Palearctic and Nearctic regions. The species exhibits striking polymorphism in both coloration and wing development, with long-winged (macropterous) and short-winged (brachypterous) morphs coexisting in populations. It is strongly associated with moist habitats, particularly wet meadows, riverbanks, and mudflats, where it feeds primarily on algae and mosses. The species has been extensively studied for its wing dimorphism, reproductive interference with congeners, and life-history trade-offs between flight capability and reproduction.
