Summary

Trogossitidae, or bark-gnawing beetles, are a family of predatory beetles associated with wood, commonly found under bark or in association with fungi. They have undergone taxonomic revisions reducing their number of species significantly from older classifications.

Physical Characteristics

Size ranges from 5 to 22 mm, with some exotic species growing up to 50 mm; generally cylindrical or slightly flattened body shape.

Identification Tips

Identifiable by their subcortical habitat and predatory behavior, as well as the structure of their antennae which are adapted to detect odors.

Habitat

Forests; commonly found under bark or on bracket fungi; some species inhabit stored products.

Distribution

Worldwide distribution, with nearly half of the described species occurring in South America.

Diet

Predatory on other beetles and their larvae; also feed on fungi during both adult and larval stages.

Life Cycle

Details on specific life cycle stages are not provided; generally includes both predation and fungal feeding phases.

Ecosystem Role

Play a role in controlling beetle populations and decomposing wood by feeding on fungi.

Collecting Methods

  • Hand collection under bark
  • Traps near decaying wood

Preservation Methods

  • Pinning
  • Drying

Evolution

The family has been restricted in its definition; the oldest fossil assignable to this family is from mid-Cretaceous, indicating early diversification.
