Pupae with dark eyes emerge as adults in about 48 hours. The total life cycle may be as little as 14 to 15 days, to well over 3 weeks. A good average development time is 17 to 21 days. Newly emerged female adults feed for about 3 days, mate, and start laying eggs. The best indicator of weevil damage and a need for treatment is punctured squares.
Females are five to six times more destructive than are the males.
