Zophobas opacus (Sahlberg，1823) was raised in the laboratory at 28℃, RH 75% . The result showed that its growth period included the adult stage (60～90 days), the egg stage (6～7 days), the larval stage (90～110 days), the prepupal stage (3～4 days) and the pupal stage (10～11 days). Meanwhile, its living habits were observed, indicating that this beetle was polyphagous; the pupation of mature larvae was inhibited and the cannibalism of adult and larvae was crowded. The mature larvae could construct a cocoon in earth. The adult secreted two chemical defence substances by two pairs of defensive glands in prothoracic and abdominal, copulation, reproduction and so on.
