Chironomus plumosus
buzzer midge
Chironomus plumosus, commonly known as the buzzer midge, is a nonbiting midge species distributed throughout the Northern Hemisphere. Adults are known for forming large mating swarms during spring and summer. The species is part of a sibling-species complex that includes C. muratensis and C. nudiventris, which cannot be morphologically distinguished from C. plumosus in adult form. The larvae, often called bloodworms due to their red coloration, are important food sources for fish and other aquatic predators.
