Rose chafer larvae overwinter in the soil. As temperatures rise in the spring= larvae move up towards the soil surface and pupate. In a few weeks adult beetles emerge and begin feeding for a period of about four to six weeks. Females deposit groups of 6-40 eggs about six inches below the soil surface in sandy or grassy areas. Larvae hatch in one to three weeks, depending on temperature, and begin to feed on roots. One generation occurs annually in Virginia.
