Nut Weevil

Found in temperate and tropical forests, orchards, and urban areas near nut-bearing trees like oaks, hickories, and pecans.

Larvae feed on the meat inside nuts (acorns, walnuts, chestnuts); adults feed on the leaves and developing fruit of host trees.

Adults emerge in summer/fall to mate and drill holes into developing nuts to lay eggs. Larvae develop inside the nut and exit to pupate in the soil once the nut falls.

Generally harmless to humans and do not bite or sting. They are considered agricultural or garden pests as they can damage nut crops, but they provide a food source for birds and small mammals.
