Tritoma
Tritoma is a genus of beetles in the family Erotylidae, the pleasing fungus beetles. It is distributed worldwide, mainly in the Old World. There are over 100 species.
Some species consume euagaric mushrooms, staying concealed amidst the gills as they feed. Some feed on mushrooms growing from dead trees, as well as mycorrhizae on living roots. One of the most common pleasing fungus beetles in Europe, T. bipustulata, is a black beetle with red spots which engages in autohaemorrhaging as a defensive behavior.
Molecular analysis suggests that Tritoma is paraphyletic, and might be best treated as two separate genera.Species
