Bostrichidae
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.
