Pyrochroidae

Definition

A family of tenebrionoid beetles (Coleoptera) commonly known as fire-coloured beetles, characterized by adults typically 2–20 mm in length and larvae reaching up to 35 mm. Larvae are primarily associated with the bark of dead trees, where they feed mainly on fungi, though cannibalism may occur under crowded conditions. The family is distributed worldwide with greatest diversity in temperate regions.

Etymology

From Greek pyro- (fire) + -chroid (coloured), referring to the typically bright orange, red, or yellow coloration of adults.

Example

Larvae of Pyrochroinae, a subfamily within Pyrochroidae, inhabit decaying bark and function as important decomposers in forest ecosystems through their fungivorous feeding habits.

Synonyms

• fire-coloured beetles

Usage Notes

Sometimes misspelled 'Pyrochroididae' in older literature. The common name 'fire-coloured beetles' applies to the family as a whole, though not all species are brightly coloured. Distinguished from superficially similar families such as Oedemeridae (false blister beetles) by antennal structure and larval habitat preferences.
