Chironomus dilutus
Chironomus dilutus is a freshwater non-biting midge species in the family Chironomidae, described in 1999. The species has become a standard test organism in aquatic toxicology, particularly for chronic toxicity assessments of sediment-associated contaminants including pyrethroids, fluorotelomer acids, selenium, and microplastics. Laboratory studies demonstrate its sensitivity to various organic pollutants, with emergence and reproduction serving as key toxicological endpoints. The species is used in regulatory testing protocols for evaluating ecological risks of hydrophobic contaminants in freshwater systems.

Eulimnadia geayi
Eulimnadia geayi is a small freshwater crustacean in the family Limnadiidae, commonly known as clam shrimp. First described by Eugen von Daday in 1913, this species inhabits temporary aquatic habitats across Central and South America. Like other members of its genus, it produces drought-resistant eggs that survive in dry sediment until rainfall triggers hatching. The species plays a role in ephemeral pool food webs as both a detritivore and prey item.

Helophorus tuberculatus
Helophorus tuberculatus is a Holarctic species of water scavenger beetle in the family Helophoridae. It is distributed across northern Europe, Russia, northern Asia, and North America. The species inhabits aquatic environments and is part of a genus known for species-specific pronotal granulation that aids identification. Like other Helophorus species, it is presumed to have terrestrial predaceous larvae.

Lacunicambarus diogenes
devil crayfish, devil crawfish
Lacunicambarus diogenes, commonly known as the devil crayfish or devil crawfish, is a primary burrowing crayfish native to eastern North America. This species constructs and inhabits burrows in wet, muddy terrestrial habitats rather than living in permanent surface water. Its burrowing activities create refugia used by numerous other species, including documented use by eastern cicada killer wasps (Sphecius speciosus) as brooding habitat. The species ranges across the Atlantic Coastal Plain and Piedmont ecoregion from New Jersey to Georgia, with disjunct populations in Louisiana.

Radotanypus
Radotanypus is a genus of non-biting midges (Chironomidae) established by Fittkau and Murray in 1985. The genus belongs to the subfamily Tanypodinae, a group of predatory midges whose larvae inhabit aquatic environments. Species-level taxonomy remains poorly documented in public sources.
