Bolitophagini

W. Kirby, 1837

Bolitophagini is a tribe of ( ) comprising more than 20 . The tribe is named after its genus Bolitophagus, whose name derives from Greek meaning '-eater'. Members are primarily associated with forest and feed on fungi, particularly bracket fungi (polypores). The tribe has a fossil record extending to the Eocene, indicating long-term persistence in forest .

Identification

of Bolitophagini are generally , convex-bodied . The tribe is distinguished from related tribes primarily by larval and adult morphological characters including details of antennal structure, tarsal formula, and male . Generic-level identification requires examination of these structural features; identification often relies on subtle differences in body proportions, surface , and genitalic .

Habitat

Old-growth forests and mature woodland . Members are specifically associated with decaying wood and fungal fruiting bodies. The fossil Eledonoprius has been associated with old-growth forest since at least the Eocene.

Distribution

Widespread in the Northern Hemisphere with records from the Western Palaearctic (Europe), Eastern Palaearctic (Korea, Japan), and fossil evidence from Baltic amber indicating historical presence in northern Europe since the Eocene.

Diet

, feeding on fungal fruiting bodies. The name Bolitophagus and tribe etymology explicitly reference -feeding. Specific associations include bracket fungi (polypores) in the genus Boletoxenus, though detailed host records for most genera remain limited.

Behavior

and are associated with fungal fruiting bodies on decaying wood. is presumed to include feeding on fungal tissue and breeding in or near fungal substrates, though specific behavioral observations are sparse in published literature.

Ecological Role

Fungivores that contribute to in forest by consuming fungal fruiting bodies and potentially facilitating spore through movement between fungal substrates.

Human Relevance

Minimal direct economic importance. Some may serve as indicators of old-growth forest continuity due to their specific ecological requirements.

Fossil record

The tribe has a documented fossil : Eledonoprius incoronatus from Eocene Baltic amber represents the first confirmed fossil member, indicating that at least some lineages within Bolitophagini have persisted in Western Palaearctic forest for approximately 50 million years.
