Digs a burrow, one egg per chamber, into each of which it places a large insect such as a cicada or katydid which provides food for the hatched young.
Novice identification is simple, in that:
- Wasps fly with their feet trailing below rather than tucked up against their bodies like bees and hornets
- No other wasps in North America are both this large and an unmarked dark black/blue-black. eg, Cuckoo Wasps are also blue-black, but are very small, and Great Golden Digger Wasps are large, but browner and with markings.
