False Bombardier Beetle
Hi Michael,
This is a False Bombardier Beetle, probably Galerita bicolor. You can compare your image to photos on BugGuide. False Bombardier Beetles are predatory ground beetles and they will not harm your home bug BugGuide indicates this “Caution: This genus has chemical defenses, see Defensive production of formic acid (80%) by a carabid beetle : Proc Natl Acad Sci U S A. 1997 June 24; 94 (13): 6792–6797. “
