Hypopygium is characterized by the presence of 3 or more (very rarely 2) strong setae at the apex of the lobes, not less than 4 (0-8) spines present on the lobes of the 8th tergite. Fourth instar larva. The bases of the postclypeal setae are closely set compared to the bases of the inner frontal setae: index ( to ) (Fig. 62, b). Pupa. The posterior margin of the paddle, unlike that of C. a. annulata, usually has pointed long denticles placed in a single row (Fig. 56, 8 and 9). Distribution (Fig. 63). In the USSR: Central Asia and Kazakh- stan, stray collections in the Caucasus and in the central Volga region. Everywhere in Europe; northern Africa (Morocco, Algeria, Tunisia); Asia Minor, Iran and Iraq. Biology. These are mosquitoes of the forest-free plains. Found rarely in human habitations. Attack large mammals but rarely man. The preimaginal stages are eurytopic, found in fresh and saline (up to per thousand), more often in 0-mesosaprobic pools with mod- erately hypothermal or isothermal range; avoid heavily shaded zones. In the northern sections of their distribution range, poly cyclic with female diapause (life form II), in the south, polycyclic without.
