Chironomus is a genus of nonbiting midges in the subfamily Chironominae of the bloodworm family, Chironomidae, containing several cryptic species that can only be distinguished by experts based on the characteristics of their giant chromosomes.

2023年10月26日 · The haemolymph of the red Chironomus larvae, called "bloodworms," contains hemoglobin, unusual for insects. Larvae are often very abundant and are an important food item for many freshwater fish and other aquatic animals.

The Chironomidae (informally known as chironomids, nonbiting midges, or lake flies) comprise a family of nematoceran flies with a global distribution. They are closely related to the Ceratopogonidae, Simuliidae, and Thaumaleidae. Many species superficially resemble mosquitoes, but they lack the wing scales and elongated mouthparts of the Culicidae.

couplet 54, p. 8.24, are Chironomus. As part of an effort to better define Chironomus and Einfeldia (see Epler et al. 2013: 400), some species previously placed in Einfeldia have been moved (temporarily?) to Chironomus. Thus the sometimes common inhabitant of eutrophic waters is now called Chironomus natchitocheae Sublette.
