Phenology of some chironomid species (Diptera, Chironomidae) of the Middle Urals

Abstract

Flight period results of chironomid species from the Middle Urals are grouped into eight categories. Six different peaks of chironomid flight activity during the year are established, namely: early-spring, late-spring, July, late-summer, early-autumn and winter. The flight periods of chironomids from the Middle Urals and southern Swedish lakes are compared.
