Argia bipunctulata
seepage dancer
Argia bipunctulata, commonly known as the seepage dancer, is a species of narrow-winged damselfly in the family Coenagrionidae. It is native to North America and holds a conservation status of Least Concern (LC) according to the IUCN, with a stable population and no immediate threats to its survival. As a member of the genus Argia—the largest genus in the subfamily Argiinae—this species exhibits the characteristic "dancing" flight pattern typical of its congeners.
Chasmatonotus
Chasmatonotus is a genus of non-biting midges in the family Chironomidae, subfamily Orthocladiinae. The genus contains approximately 14 described species and exhibits a disjunct distribution spanning Japan, the Nearctic region, and Continental Asia. Adults are fully winged but non-flying, a distinctive trait among chironomids. The genus was historically considered restricted to Japan and North America until the 2023 discovery of a species in Korea.
Euparyphus stigmaticalis
Euparyphus stigmaticalis is a species of soldier fly (Diptera: Stratiomyidae) described by Loew in 1866. It is known from eastern North America, where it occurs in specialized madicolous habitats—seepage areas on rock faces with thin films of flowing water. The species has been studied for its biology and immature stages, which are adapted to life in these thin water film environments.
