These wasps nest each summer in pre-existing holes in the spruce stump. They are solitary wasps that provision their nest with orthopterans (grass hoppers, crickets, etc.), and use grass to plug their nests. The adults take nectar from a wide variety of flowers.
Several of these have nested in on old spruce stump. I've seen them carrying grass to nest holes. There are six completed nests with grass sticking out of holes.
