Cerambycidae

Definition

A large family of beetles (order Coleoptera, superfamily Chrysomeloidea) characterized by extremely long antennae—often exceeding body length—and elongate, cylindrical bodies. The family comprises more than 35,000 described species in roughly 12 subfamilies, including Cerambycinae, Lamiinae, and Prioninae. Larvae are typically wood-borers, developing in living or dead trees, and many species are economically significant as forest pests or vectors of plant pathogens. Adults are often diurnal, flower-visiting, or chemically defended, with aposematic coloration common in tropical lineages.

Etymology

From Cerambyx, the type genus (Greek kerambux, a kind of beetle) + -idae, the standard family suffix in zoological nomenclature

Example

The Asian long-horned beetle (Anoplophora glabripennis, subfamily Lamiinae) is an invasive cerambycid that threatens hardwood forests in North America and Europe.

Usage Notes

Cerambycidae is the formal family name; "longhorn beetle" is the common name. The family is distinguished from other Chrysomeloidea by the combination of long antennae (though some lamiines have reduced antennae in females), tarsi with a distinct membranous lobe on the fourth segment, and typically elongate body form. Some authors split Disteniinae and Oxypeltinae as separate families, but most current classifications retain them as subfamilies of Cerambycidae. The term "cerambycid" (adjective/noun) refers to members of this family.
