  • An insect of a family (Chironomidae) that comprises the nonbiting midges.

    • ‘By 10-11 days after hatching, young gar begin feeding on small crustaceans, such as cladocerans and copepods, and insects, including various dipterans such as chironomids.’
    • ‘Fish were held in large plastic tanks or large aquaria when not being used, and they were fed frozen chironomids and live damselfly larvae.’
    • ‘As river fish and their invertebrate prey, such as chironomids and caddis larvae, have evolved together, each has influenced the behaviour of the other.’
    • ‘Young Atlantic salmon in streams eat mainly the larvae of aquatic insects such as blackflies, stoneflies, caddisflies, and chironomids.’
    • ‘The worms are actually the dark-red larvae of non-biting mosquito-like insects known as chironomids, more commonly called midges.’
