Adult crown borers are short-snouted, reddish-brown, flightless weevils about 1/5-inch long. Their wing covers are marked with three pairs of darker spots. Adults, which overwinter in plant debris in strawberry fields or in surrounding areas, become active in the spring at about the same time that strawberries begin to bloom. They feed in crowns to open holes into which they lay eggs that hatch in about one week. Egg-laying continues through mid June. Yellowish, legless grubs feed for several weeks in strawberry crowns before pupating in late summer. Adults emerge in the fall, feed on strawberry foliage, and then seek shelter in plant debris to pass the winter.
