Leaf beetles are another large beetle family with over 37,000 species in more than 2,500 genera and distributed mainly throughout the tropics. Leaf beetles are usually oval-shaped and short-legged, with the antennae about half the body length, and tend to be less than 12 mm long. No single character defines the Chrysomelidae, in fact some species are only distinguished with difficulty from short-antennae longhorn beetles by the antennae not arising from frontal tubercles. Adults and larvae feed on all sorts of plant tissue.
