Agathidium
slime mold beetles
Agathidium is a genus of small beetles in the family Leiodidae, notable as the largest insect group documented that principally feeds on slime moulds. The genus includes approximately 100 described species distributed primarily across the Holarctic region. Several species have gained public attention through their unconventional scientific names honoring political figures and fictional characters. Some species possess the ability to roll into a nearly complete sphere, and males of certain species exhibit asymmetrical mandibular horns used in combat and courtship.
