We found this wasp on Dec 2009 in Daisy Hills near Buhot Creek. It was building a nest on the sandy ground with small rocks. The nest was only it body size in deep so it must be a newly build nest. When the wasp was inside, we hear the loud and high pitch buzz noise than the wasp carried a small rock out side the nest. Those rocks were usually half the body size of the wasp.

We we came too closely the wasp flied toward us and make the loud buzzing sound. when we move back a bit, the wasp return to the nest and keep digging.
