The carrot Weevil adult is a dark-brown snout beetle about 1/5" long . It over winters in plant debris in and about carrot fields that were infested the previous season - which is another good reason for Crop Rotation.
In spring, adults become active and mate after a few warm days. They are capable of laying eggs by mid- to late May. However, they do not attack the new crop of carrots until the first true leaf stage.
Adult females chew small cavities in the petioles or crown of the carrots , sealing the cavity with a black exudate. Eggs hatch after one to two weeks and the young larvae tunnel down into the root or leave the stalk and enter the roots from the soil. Some young plants may wilt and die.
The larvae also attack celery, parsnips, and parsley. Their meandering tunnels can be found in carrot tops and the roots of infested plants. Plants can easily be defoliated completely.
