Identification

Distinguished from other by the slight waist or constriction between the pronotum and . Separated from Erotylidae (pleasing fungus beetles), Endomychidae (handsome fungus beetles), Mycetophagidae (hairy fungus beetles), Derodontidae (tooth-necked fungus beetles), Tetratomidae (polypore fungus beetles), Archeocrypticidae (cryptic fungus beetles), and Ciidae (minute tree-fungus beetles) by this body shape feature combined with small size and association with fungi.

Habitat

Associated with fungi in diverse situations including rotting wood, shed animal fur, feathers, and mushroom fruiting bodies. Found in terrestrial environments where fungal growth occurs.

Distribution

distribution with representatives in all biogeographic realms. Documented from North America, Europe, Asia (including Himalayan region of China and India), Africa (eastern mountains, Kenya), and other regions. Fossil record includes Lebanese amber (Early Cretaceous, Barremian), Taimyr amber (Late Cretaceous, Santonian), Shixi Formation (Early Cretaceous, Albian), El Soplao amber (Albian), and Baltic amber (Eocene).

Diet

and larvae feed exclusively on fungi.

Ecological Role

Primary consumers of fungi; contribute to nutrient cycling in decomposing organic matter. Serve as prey for predatory beetles such as rove beetles (Staphylinidae).

Human Relevance

Occasionally found in mushroom where they may be considered pests. Attracted to blacklight traps.
