This species may be separated from C. punctatus by the dark tips to wing veins M1, M2 and CU1, but a clear distinction between the two is often difficult (Lane 1981). See also the notes under C. punctatus The female antennal ratio is 0.98-1.09; the sensilla distribution 3,11-15. The male genitalia are virtually inseparable from those of C. punctatus.
It has been recorded biting cattle, sheep, horses, buffaloes and man. Dzhafarov (1964) gives details of its biology and times of appearance in Russia. Downes (1955) gives notes on its swarming behaviour.
Widely distributed and often common over the whole of the Palaearctic region, through to Pakistan and the Middle East.
African horse sickness virus has been isolated from a mixed pool of this species and C. obsoletus in Spain (Mellor et al., 1990). The bites are known to cause the allergic condition “sweet itch” of horses (Mellor & McCaig 1974).
