Mystery Bug
Hello,
This bug drilled a perfect hole in the ceiling of our newly refinished basement, any ideas? It was found dead under the hole covered in sheetrock dust. Any clues to solve this mystery would be appreciated.

Hi Greg,
Your Horntail species did not drill a hole into the ceiling, but rather bored out of the ceiling. The larvae are wood borers. Our guess is the wood used in the refinishing was infested, hopefully with a single larva, and when it matured, it drilled its way out.
