In late summer we saw this wasp on a dead tree trunk. It spent a lot of time checking each hole on the dead tree trunk. We believed those holes were made by the beetle larvae. The wasp was looking for those larvae, if found, will bring back to its nest for its young.

The wasp check every holes.  For some holes, the wasp went inside and spent tens of seconds inside. We watched it for a few minutes, it had no luck and could not find any yet.
