Heath Sand Wasp (Ammophila pubescens)

This, and the very similar Red- banded Sand Wasp Ammophila sabulosa, both breed on the Common, provisioning their nests with caterpillars.  The Heath Sand Wasp female makes several nests and checks each in turn once the larvae have hatched.  She carefully closes each nest with little stones and sand between visits, and remarkably remembers where each is.
