About 1910 the beetle was found in Connecticut and has since become a serious ornamental pest in southern Canada and the northern United States. Host Plants -Many herbaceous and woody plants have been listed as hosts for the black vine weevil. Damage -Black vine weevil larvae can stunt the growth of a plant by feeding on the roots. Larger roots are stripped of their bark or girdled, or they have notches chewed out of them. The interior, older foliage is preferred to the terminal growth.
Life History -Black vine weevils overwinter as mature larvae or as pupae.
However, a few adults also survive the winter to feed and deposit eggs during a second season. This weevil is parthenogenetic. Although one female was recorded as laying 863 eggs, the average number of eggs deposited by each female is probably about 200. During the preoviposition period, which lasts about 45 days, the adults feed most extensively. The longevity of the adult usually ranges from 90 to 100 days.
