Chironomus riparius, also known as Chironomus thummi and commonly known as the harlequin fly, is a species of non-biting midge. Their larvae are known by the common name of blood worm due to their red colouration. It is common in both North America and Europe.

A midge is any small fly, including species in several families of non-mosquito nematoceran Diptera. Midges are found (seasonally or otherwise) on practically every land area outside permanently arid deserts and the frigid zones. Some midges, such as many Phlebotominae (sand fly) and Simuliidae (black fly), are vectors of various diseases.
Larvae of Chironomus usually live in aquatic sediment. Those of the C. decorus group, C. riparius group and C. stigmaterus generally live in conditions of high nutrients and low oxygen. There are also Chironomus that live in relatively clean water. [2] The larvae of several species inhabit the profundal zone where they can reach relatively high ...
The life history of T. akamusi consists of four stages: egg, larva, and adult. Most of its lifetime is spent in the larval stage at the bottom of freshwater bodies, which spans from 1 to 3 years. Midge larvae are commonly called bloodworms, because of their red color from the hemoglobin molecules
Larvae with red or orange hues are characteristic of D. mali, though differentiation from other species can be challenging, as larvae may also exhibit a yellow or white colour. [6] To identify D. mali larvae, the length of setose papillae on the first thoracic segment and the shape of the sternal spatula are measured. [4]
