The longhorn beetles are a cosmopolitan family of beetles, typically characterized by extremely long antennae, which are often as long as or longer than the beetle's body. In various members of the family, however, the antennae are quite short and such species can be difficult to distinguish from related beetle families such as the Chrysomelidae. The family is large, with over 26,000 species described, slightly more than half from the Eastern Hemisphere. Several are serious pests. The larvae, called roundheaded borers, bore into wood, where they can cause extensive damage to either living trees or untreated lumber. A number of species mimic ants, bees, and wasps, though a majority of species are cryptically colored. The rare titan beetle from northeastern South America is often considered the largest insect, with a maximum known body length of just over 16.7 cm (6.6 in). The scientific name of this beetle family goes back to a figure from Greek mythology: after an argument with nymphs, the shepherd Cerambus was transformed into a large beetle with horns.
The Chrysomeloidea are an enormous superfamily of beetles, with tens of thousands of species, mostly in the families Cerambycidae and Chrysomelidae, the leaf beetles.
Lamiinae, commonly called flat-faced longhorns, are a subfamily of the longhorn beetle family (Cerambycidae). The subfamily includes over 750 genera, rivaled in diversity within the family only by the subfamily Cerambycinae.
The Rhyparochromidae are a large family of true bugs, many of which are commonly referred to as seed bugs. The family includes two subfamilies, more than 420 genera, and over 2,100 described species.
The Disteniidae are a small family of beetles in the superfamily Chrysomeloidea, traditionally treated as a group within the Cerambycidae.
The Oxypeltidae are a small family belonging to the superfamily Chrysomeloidea, widespread in the Andean region of Chile and Argentina. They have traditionally been considered a group within the Cerambycidae.
Cerambycinae is a subfamily of the longhorn beetle family (Cerambycidae). The subfamily includes over 715 genera, which, in total, consist of some 3,900 species. The subfamily is most widely distributed in the Americas, with 430 species in 130 genera in its neotropical regions. Within the family, the only subfamily of comparable diversity is the Lamiinae.
