Digger Wasps are solitary wasps, and as their name suggests, they dig holes to nest in the ground. These holes are also used to store their paralysed prey (other insects, larvae or even spiders). This one is actually called a Slender Bodied Digger Wasp (Crabro cribrarius) and is characterised by the large paddle shaped front tibia, which are used in the burrow excavation. They prefer dry sandy areas such as the coastal dunes.
