I watched this wasp as it dug a furrow about 6 inches long leading up to the hole shown in the first image. It then disappeared head-first into the hole. Once inside it began buzzing. After a few seconds it backed out, flew around a bit landing on various substances within a 4 meter radius before repeating the process.
I would like confirmation of the id, but also any insight into the behavior. What was the buzzing about? It did not appear to make this sound outside the hole - although it is possible the hole acted as an amplifier and I just did not hear it while the wasp was outside the hole.
Is the hole a nest? Or was it looking for some prey there? (I did not notice any other insects around the hole.)
