Scepticus griseus Roelofs and S. uniformis Kôno are pests of carrots, burdocks, welsh onions, and peanut crops in Chiba Prefecture. Overwintering adults had a low threshold temperature of development of 1.1°C, and a total effective temperature of 112 degree during the preoviposition period. Overwintered adults produced eggs from April through August. Callow adults produced eggs in September, and wintered in October.
