Anurida
Anurida is a genus of springtails (Collembola) in the family Neanuridae, established in 1865 by Laboulbène. The genus has cosmopolitan distribution with species occupying diverse habitats including intertidal marine zones, river floodplains, riparian areas, and forest ecosystems. Well-studied species include the intertidal specialist Anurida maritima, which exhibits complex tidal-entrained behaviors, and the terrestrial A. granaria, which has documented mycophagous associations. The genus shows notable morphological diversity in chaetotaxy and eye reduction, with some species groups exhibiting cryptic genetic divergence despite morphological similarity.

sulphurella
Elymana sulphurella is a leafhopper species native to Europe, introduced to North America. It is a phloem-feeding specialist on grasses (Poaceae), with documented suitability for multiple host species including Agrostis, Elymus, Festuca, and Phleum. The species exhibits egg diapause requiring cold treatment to reduce incubation time. Development from egg to adult averages 24.9 days for females and 23.5 days for males. Mated females show significantly greater longevity than males.
Lestes disjunctus
Northern Spreadwing
Lestes disjunctus, commonly known as the Northern Spreadwing, is a damselfly species in the family Lestidae. It is widely distributed across North America and inhabits a variety of freshwater habitats including riverine wetlands, ponds, and marshes. The species exhibits a univoltine life cycle with egg diapause, requiring overwintering before hatching. Adults emerge in late June through July and remain active until late August. Larvae are predatory, feeding primarily on zooplankton and small aquatic invertebrates. The species holds its wings at approximately 45 degrees to the body when at rest, a characteristic posture of spreadwing damselflies.
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.
Trigonotylus
rice leaf bug
Trigonotylus is a genus of plant bugs in the family Miridae, tribe Stenodemini, containing approximately 18 described species. The genus has a cosmopolitan distribution with species in North America, Europe, Asia, and Hawaii. Several species are associated with grasses (Poaceae), with T. caelestialium being a significant agricultural pest of rice in Japan. The genus exhibits variation in host plant use, oviposition behavior, and seasonal life history strategies.
