Abstract
The studies on the chironomids in Lake Suwa are reviewed with special reference to the information on larvae. Since 1928, many investigators have studied chironomid fauna as well as their population dynamics, larval distribution on the lake bottom, swimming behaviour, predation by fish, their roles in the material cycles, etc. The changes in population densities of Propsilocerus akamusi and Chironomus plumosus larvae in relation to the eutrophication of Lake Suwa are discussed. Furthermore, recent characteristics of chironomid ecology in Lake Suwa are examined and future sub-jects matters are suggested.
