On Saturday night this not-quite-two-inch beetle came to our door. It seems to be Mallodon dasystomus, the hardwood stump borer, and displays the characteristic golden fur on the inside surface of its mandibles.

Hardwood Stump Borer

Dear Lachlan,
We believe you are correct that this is a Hardwood Stump Borer.  According to BugGuide:  “Larvae bore in live heartwood of trees, incl. oak, elm, willow, pecan, maple, sycamore, etc” and “take 3-4 years to mature. Can be economically damaging. Adults come to lights.”  However, we would not rule out that it might be a Live Oak Root Borer,
Archodontes melanopus, which is also pictured on BugGuide.  We will attempt to get an exact species identification for you.
