Apatides fortis (Bostrichidae), the Horned Powder-Post Beetle

Tucson, Arizona

These robust wood-boring beetles have been common at my blacklight in early monsoon season. Good thing, too.  We collected a few for the Beetle Tree of Life study, and they’ve been one of the easier beetles to produce DNA sequence for our project.

    was just wondering if this beetle, Apatides fortis, would also be found in Souther Cali.? As I think I had one in my house.

    Would this beetle, Apatides fortis, also be found in Southern Cali?
