A new population of the phytophagous ladybird, Epilachna yasutomii showing a relatively-wide food range was found in Nishitsugaru-gun, Aomori Prefecture. In the laboratory, adults and larvae both fed on leaves of Caulophyllum robustum, Panax japonicus, Hylomecon japonicum and potato (Solanum tuberosum). Due to the wide food range in the natural habita+, about 10% of adults had invaded an adjacent potato field.
