Weevils have antennae that are bent in what is called an 'elbow'. Many species also have curled 'snouts' or 'noses' that are helpful in categorizing them. Almost all are herbivores, and many are notorious for the devastation they cause on important crop plants and trees.
They are generally quite small and are often overlooked unless there are large numbers of them. They can infest pantries that have not properly stored grains, and garages with opened birdseed. Their larvae can bore through the cambium tissue of trees, interrupting the flow of water and nutrients, like the Larger Chestnut Weevil, or attack the roots, like the Little Leaf Notcher. Some attack the buds of plants, ruining the yield, like the infamous Boll Weevil. Efforts to control, and even eradicate, certain species of Weevil are common. Finding one indoors should inspire a quick check of cupboards, the pantry, and other areas with food sources. Weevils reproduce rapidly, so early discovery of an infestation makes removing it easier.

Antennae: Beetles have a pair of antennae on the head used for sensing.
Head: The head is home to the insect's eyes, antennae, and mandibles (jaws).
Thorax: Holds the three pairs of legs as well as vital internal organs.
Elytron: One of two wing cases on a Beetle that protects its wings (plural: elytra).
Wings: Appendages used for flying and kept under the elytra until needed.
Abdomen: Houses organs related to circulation, reproduction, and excretion.
Legs: Beetles have three pairs of legs located at the thorax, numbering six legs in all.
