Digger Wasps are not closely related to the Spider Wasps, but behave accordingly. They are not very specialized and use all kinds of animals, mainly the larvae of insects , such as butterflies, moths, locusts and flies, but adults and spiders as well. These are paralyzed and then transported to the nest, often a self digged hole in the ground. Some of the better known Digger Wasps have a very characteristic body, and are therefor immediately identified as wasps.
For the larvae may be meat eaters, the adult Sand Digger Wasps feed on pollen! This is a large species, that can be well over two centimeters in length. In the pictures a male feeding.
