Adults will take fruit and meat in captivity; may feed on other insects
Life Cycle
Adults come to lights. Larvae in rotten logs, esp. oaks. Adults can live up to two years in captivity. Have structures for sound production (stridulation)(5) and stridulate softly when handled (P. Coin, 11.vii.2007).
Larvae and adults are also "carnivorous" and will - if not preferentially - feed on grubs & pupae of other scarabs
