Checkered beetles

Definition

Common name for beetles of the family Cleridae, a moderately diverse group of predatory and scavenging Coleoptera recognized by their often strikingly patterned elytra—typically banded or mottled in red, black, yellow, or blue. Adults frequent flowers, bark, and decaying wood where they prey on other insects, especially larvae of wood-boring beetles (Cerambycidae, Buprestidae) and eggs or pupae found under tree bark; some species are stored-product pests or feed on pollen. Larvae are generally campodeiform, active predators of soft-bodied insects in similar habitats. The family is cosmopolitan with roughly 3,500 described species, though most diverse in tropical and subtropical regions.

Etymology

From the characteristic contrasting color patterns on the elytra resembling a checkerboard or banded design.

Example

Trichodes ornatus, a western North American species, aggregates on flowers to feed on pollen and mates, while its larvae develop in bee and wasp nests as cleptoparasites or predators of host larvae.

Usage Notes

The common name refers specifically to family Cleridae, not to any beetles with checkered patterns in other families (e.g., some Carabidae or Chrysomelidae). Specialists typically use 'clerid beetles' or simply 'Cleridae' in formal contexts. The name emphasizes visual pattern over biology; not all species are boldly patterned, and some are uniformly colored.
