Tritoma sanguinipennis

Tritoma is a genus of beetles in the family Erotylidae, the pleasing fungus beetles. It is distributed worldwide, mainly in the Old World.[1] There are over 100 species.[1]

Some species consume euagaric mushrooms, staying concealed amidst the gills as they feed.[2] Some feed on mushrooms growing from dead trees, as well as mycorrhizae on living roots.[3] 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.[4]

Molecular analysis suggests that Tritoma is paraphyletic, and might be best treated as two separate genera.[2]
