Weevils are usually small, only about a ¼ of an inch. They have a long snout that is very often as long as the rest of it's body. They use this snout to find food underneath the surface of plants and trees, and their mouth is made for chewing. Weevils feed on plants, and can have two or three broods of young annually. Most weevils cause no harm, though some lay their eggs and feed in your crops, where they can reduce yield if they are abundant.
