SUMMARY An area of black currants in Kent, which had been cut for mechanical harvesting in July 1970, was observed in the following spring to be uniformly infested with larvae of Clepsis spectrana , whilst adjacent bushes which had been hand picked were practically free from larvae. This difference was attributed to adults preferring the post‐harvest growth, which occurred only on mechanically harvested bushes, as a site for oviposition.
