Attenella margarita
spiny crawler mayfly
Attenella margarita is a species of spiny crawler mayfly in the family Ephemerellidae. It exhibits a disjunct east-west distribution pattern across North America, which is rare among mayflies. The species has been documented from the southern half of Canada and the continental United States, with a southeastern range extension to North Carolina representing approximately 1,300 km beyond previously known western localities.
Coelotanypus tricolor
Coelotanypus tricolor is a species of non-biting midge in the family Chironomidae, subfamily Tanypodinae. It belongs to the tribe Coelotanypodini and was first described by Loew in 1861. As a member of the Tanypodinae, it is classified among the predatory midges rather than the filter-feeding Chironominae. The species epithet 'tricolor' suggests a three-colored appearance, though specific color pattern details are not well documented in available sources.
Neoleptophlebia assimilis
Southeastern Prong-gilled Mayfly
Neoleptophlebia assimilis is a species of prong-gilled mayfly in the family Leptophlebiidae. It is known from the southeastern United States. The species belongs to a genus characterized by gills with divided, finger-like lobes. Mayflies in this family are typically associated with running water habitats and serve as important indicators of water quality.
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.
Stenacron carolina
Carolina flat-headed mayfly
Stenacron carolina is a species of flatheaded mayfly in the family Heptageniidae. It is found in North America. The species was described by Banks in 1914. Like other members of the genus Stenacron, it is associated with aquatic habitats.
Stenelmis crenata
riffle beetle
Stenelmis crenata is a species of riffle beetle in the family Elmidae, occurring in North America. It inhabits fast-flowing stream environments, particularly riffle habitats in tallgrass prairie streams. The species exhibits a multivoltine life cycle with overlapping cohorts and year-round larval presence. Adults are active from late spring through autumn.
