Like all the members of the Staphilinini tribe, D. pleuralis possesses paired eversible defensive glands located at the tip of the abdomen. If threatened, D. pleuralis brings its last abdominal segment in contact with the threat and releases a chemical mixture (often mixed with defecations) to repell its opponent.
