Tokunagayusurika akamusi is a midge fly species of the family Chironomidae, commonly called "nonbiting midges" or "lake flies."
Described by Tokunaga in 1938, the species is common to eutrophic lakes in Japan. The midge family is very similar to the mosquito family in morphology, except that they do not feed on human blood.
The larvae are commonly called bloodworms and are used as fishing bait in Japan. Their larvae are scavengers for organic materials at the bottom of freshwater bodies. Adult midges rarely feed since they only emerge during fall and live up to a few weeks. As adult male midges emerge, they form large swarms that make dance-like movements in the air to facilitate mating, so as to attract females to approach the swarms. Such swarming behavior helps facilitate mating, but is also a severe nuisance to Japanese local residents, as well as tourists in areas close to eutrophic lakes or polluted water bodies in Japan.
