and life cycle—Root weevil
Adult weevils emerge in late spring or summer and feed on the foliage of host plants at night. Adults
do not fly, but may crawl into new plantings from nearby native plants, ornamentals, blackberries, or
second-year strawberries. Peak populations occur in summer and early fall, and some may overwinter. Eggs
are laid in the soil and around plant crowns about a month after adults have emerged.
After hatching, larvae work their way into the soil and feed on plant roots and crowns. Larvae overwinter
in the soil and pupate in the spring. There is only one generation a year.
