Chironomus atrella
Chironomus atrella is a non-biting midge species in the family Chironomidae, studied primarily through cytogenetic analysis of its polytene chromosomes. Research has clarified taxonomic confusion surrounding this name, which had been applied to at least two distinct species. Populations across North America show moderate to high chromosomal polymorphism, with heterozygosity ranging from 0.36 to 0.92 in different habitats. The species has been documented in both shallow freshwater environments and tidal coves.
