The coccinellid, Anatis mali (Say), fed singly and in groups of three to four on egg masses of the spruce budworm, Choristoneura fumiferana (Clemens). The potential of this predator as a biological control agent was investigated by reviewing the literature and establishing laboratory and field experiments on host synchrony and feeding behavior. The predaceous stages of the A. mali life cycle coincide with the spruce budworm oviposition period. The predator's generalist feeding behavior may however limit its importance as a predator of the spruce budworm.
