Clarke, C. M.— About 13 000 back-cross larvae of Callimorpha dominula L. 

 {medionigra Cockayne x typical) were introduced from Cothill, Oxon. to the Wirral 

 Way, Merseyside in 1961. The colony was rediscovered in June 198S when a male 

 bimacula Cockayne came to m.v. light, since when the colony has been studied, during 

 which time the proportions of the three forms — typical, medionigra and bimacula — 

 have remained in Hardy-Weinberg equilibrium with medionigra between 20 and 

 This contrasts with Cothill where this form is now only about 2%. Two sets of imagines 

 were exhibited, the first (1989) bred from last instar larvae from the Wirral Way, 

 together with broods using these as parents, the second imagines bred from 1993 last 

 instar larvae from the Wirral Way. 



Clarke, J. M.— The exhibit included specimens taken or bred in 1993: Cossus
