Life Cycle
Females chew holes through the bur and into the nut to make a suitable place in which to lay eggs. Each female lays about 25 eggs which hatch in about one week. Larvae feed 6 to 10 weeks then chew their way out of fallen nuts and enter the ground where they spend the winter and spring. Larvae pupate in late spring and early summer. Adults begin to appear about the first of August.
