INCIDENTAL CAPTURE OF MALE EPIAESCHNA-HEROS (ODONATA, AESHNIDAE) IN TRAPS DESIGNED FOR ARBOREAL CALOSOMA-SYCOPHANTA (COLEOPTERA, CARABIDAE)

Ten male Epiaeschna heros, the largest dragonfly in the northeastern U S, were caught unexpectedly in traps designed to catch Calosoma sycoph anta, a carabid beetle that feeds on the larvae of the gypsy moth, Lym antria dispar (Lepidoptera: Lymantriidae), and other lepidopterans. Ex amination of the intestinal contents and fecal pellets from five of th e captured E. heros revealed the remains of prey insects but no identi fiable fragments of lepidopterans. Only males were captured suggesting that the apparent attractiveness of the traps is related to breeding behavior. Modification of the traps might enhance their selectivity fo r aeshnid dragonflies.
