Found this guy in our front hallway, never seen one like this before. Just over a 1/2″ long, tan, black and looks like a little yellow detail.

Rustic Borer, we believe

Dear SDub,
We believe this Longhorned Borer Beetle is a Rustic Borer,
Xylotrechus colonus, based on images posted to BugGuide.  According to BugGuide:  “larvae develop in virtually all eastern hardwoods, especially Carya, Fagus, and also Pinus.”  BugGuide also notes:  “prefers recently killed trees” and “comes to lights; one of the commonest eastern creambycids [sic].”  Perhaps it came into the house with firewood and the warm indoor temperature caused it to emerge early.
