The Longicorns form a large family (more than 20,000) and are very varied. All members are plant and wood eaters. Most have long antennae and an elongated tube-shaped body. The coloration is varied but many species have pretty colors and/or patterns and designs (including impressive horns). Adults are found on flowers, branches, trunks, foliage, and under bark. In some species, adults rarely leave the trunks where they were raised. Many species are nocturnal. The larvae are tube-shaped wood borers. Some species are important to forests or agricultural and some species attack timber. Others are known to rub body parts together, such as their legs, to communicate and some use chemical secretions to communicate.
