Tritoma sanguinipennis

Some species consume euagaric mushrooms, staying concealed amidst the gills as they feed.^[3] Some feed on mushrooms growing from dead trees, as well as mycorrhizae on living roots.^[4] 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.^[5]

Molecular analysis suggests that Tritoma is paraphyletic, and might be best treated as two separate genera.^[3]
