Tritoma erythrocephala
Lacordaire, 1842
Red-headed Tritoma

The specific epithet "erythrocephala" (red-headed) refers to a distinctive color characteristic of this species. As a member of Erotylidae, it belongs to a family known for mycophagy (fungus-feeding) and often bright, contrasting coloration.

Defensive Chemistry
A study of the related Tritoma bipustulata (referenced in of the Week) found that pleasing fungus beetles in this produce a complex mixture of aromatic compounds including alkenes, ketones, and acids as defensive secretions from glands and in . These compounds are repellent to ants and have antimicrobial properties. While this specific defensive chemistry has been documented in T. bipustulata, it is reasonable to infer that T. erythrocephala may possess similar chemical defenses given shared genus membership in Erotylidae, though direct study of this species has not been reported.
