The adult weevils have a snout and are about one-fourth inch long. They may be reddish-brown, gray, or almost black.
Adult weevils spend the winter in ground trash near old cotton fields.
Eggs are laid singly in squares and bolls in punctures made by the weevil's snout. Both types of punctures will cause squares and small bolls to drop. The white, legless larva feeds and pupates within the square or boll. The development from egg to adult takes 3 weeks. Five generations can develop in South Carolina.
