The long-beaked insects known as weevils are actually a type of beetle. Weevils are chewing insects and their mouth parts or mandibles are located at the very tip of their snout. They use this beak to drill through the shells of nuts, fruits, bark and other plant parts so that they can feed on the softer material within. Female weevils also insert their eggs deep into plant tissues using these same drill holes. Some weevils are considered pests of the plants (white pine, spruce, alfalfa and strawberries, among others) they eat and lay eggs in. The majority, however, are innocuous, and some even eat plants like dandelions, purple loosestrife and other plants generally considered to be weeds in the Northeast.
