Peltis is a genus of beetles found in North America and Europe, and the sole extant member of the family Peltidae, formerly included in the Trogossitidae.[1][2][3][4] Members of this genus are dark, averaging from brown, to dark brown, to black. They are small, wide, and flat-bodied with wide, ridged elytra. Fossil species of this genus are known from the Eocene aged Florissant Formation of the United States, as well as the Baltic amber of Europe.
Peltis larvae feed on fungal hypae growing inside rotting wood. Larvae grow for two to three years before becoming adults.[5][6]
