Cochylis is characterized by the combination of the following characters: adult small to medium; forewing with all veins separate, Sc reach ing middle of the costal margin, basal distance between R1-R2 about three times of between R2-R3, R5 to the costal margin; hindwing with costal fold in male, Rs and M1 arising from the same point or long stalked, M3 and CuA1 separate, female hindwing usually with two spines in the frenulum; male genitalia: tegumen short and broad; uncus and gnathos absent; socius separate, drooped, connected with distal part of tegumen at base; median process of the transtilla mostly developed and dentate distally (absent in a few species); sacculus developed with a hook-shaped process basally in some species, with or without terminal process; slender vinculum separate ventrally; phallus without cornutus or with cornutus composed of a bundle of spines; female genitalia: sterigma varied in size and sclerotized diversely; antrum developed and heavily sclerotized; ductus bursae short, indistinctly distinguished from the corpus bursae; corpus bursae membranous, densely suffused with tiny spines. Biology. In the Palaearctic Region, there are one or two generations annually, and over-wintering occurs in the larval stage. Larvae are oligophagous and feed mainly on plants belonging to Asteraceae ( Razowski 1987 ). Distribution. All species are distributed in the Holarctic, Oriental and Neotropical regions.
