Extract

On 2 occasions in August 1983, during the course of a study of the arthropod community associated with collards (Brassica oleracea L. [Cruciferae]) in central New York State, the pentatomid bug Euschistus servus euschistoides (Vollenhoven) was observed feeding on larvae of the imported cabbage butterfly, Pieris rapae (L.). The individuals making the attacks, both adults, were discovered on the upper surface of a collard leaf with 4th-stage caterpillars firmly impaled on their rostra. Both caterpillars appeared lifeless. In 1 case, the P. rapae larva appeared somewhat shrunken, indicating that the bug had probably removed some body fluids from it. Voucher specimens of the bug have been deposited in the Cornell University Insect Collection (lot #1137). This note constitutes another record of predatory behavior exhibited by this nominal phytophage (Esselbaugh 1948; McPherson 1982).
