A long, thin, yellow striped wasp makes his home in our DT enclosure. He's not aggressive, and there appears to be only the one. He comes out when I water the plants. I don't want to get close enough to photograph him, but here are some of the small holes I presume belong to him. I'm inclined to leave him alone -- I think he eats the bugs who orherwise eat the Testudo mix. Any theories as to what he might be?
