Seasonal development and life cycle—Fuller rose beetle

Fuller rose beetle adults lay their tiny eggs in organic matter on the soil or on branches, leaves, or fruit. The emerging larvae enter the soil and feed on roots for 6 to 10 months and then pupate. Most adults emerge between June and November, but a few can emerge from pupae during each month of the year. Adults feed on foliage or blossoms.
