This is a large family of beetles consisting of several subfamilies. Long-Horned Beetles are medium to large-sized. The adults are rather flat, long, and oval or slightly angular. They are often black or brown, but also exhibit other colors, depending on the species. The antennae are quite long, sometimes even longer than the length of the body. The larvae bore round tunnels through the wood of various species of trees and shrubs, and can cause considerable damage. Some species of Long-Horned Beetles visit flowers to feed on pollen or nectar.
