This scenic painting on an old window frame is a favorite for Carpenter bees to bore holes into. Today I noticed a little different looking hole, and in a new spot on the frame (normally on the very bottom). At first I assumed it was just a new Carpenter bee hole, then a wasp appeared and went in and out of the hole several times. So I am wondering is is a good wasp that eats Carpenter bees? Is it a bad wasp that bores like Carpenter bees?
