What is this bug?
Love your website. Can you help me identify this bug? We found it already dead and partially hanging out of one of many holes in a railroad tie approximately one inch in size. Thanks for your help,
Cheri Mosley

Hi Cheri,
Your photo is of the traumatized remains of the Hardwood Stump Borer, Stenodontes dasystomus. Your specimen is a male as evidenced by the robust mandibles. The larvae live in the heartwood of living trees, taking three or four years to mature.
