The longhorn beetles (Cerambycidae) are a family of beetles notable for their extremely long antennae. These antennae are often as long as or longer than the beetle’s body in fact. The family is large, with over 20,000 species described. Several are serious pests, with the larvae boring into wood, where they can cause extensive damage to either living trees or to wood in buildings; the house longhorn Hylotrupes bajulus being a particular problem indoors. A number of species mimic ants and wasps, while a majority of species are cryptically colored.
