Chironomus atroviridis
(Townes, 1945)
Chironomus atroviridis is a of non-biting midge in the Chironomidae, first described by Townes in 1945 under the basionym Tendipes atroviridis. The species belongs to the Chironomus, one of the most well-studied groups of non-biting midges with over 200 species. As with other chironomids, do not bite or feed, while larvae are aquatic and play important roles in freshwater .
