| Field digger wasps are active from July to October. They prefer to live on roadsides, embankments or sand pits. Sandy or loamy soils, suitable for nesting, are of particular interest. Field digger wasps, and their brood, feed on flies. In addition, they seek out Umbelliferae or animal faeces (eg cow dung). When the field digger wasp sees a fly, it sneaks up, jumps on it and may fall with it to the ground. There, it paralyzes the fly and transports it to the nest. It may also happen that the field digger wasp does not paralyze the caught fly, but ‘kneads’ it until liquid comes from its mouth, which is then eaten by the field digger wasp. | | |

The adult wasps are mainly found on umbelliferae flowers, mint, thistle or golden rod plants. Their larvae mostly live as parasites in the nests of some kinds of bees or wasps, for example, digger wasps or solitary wasps. The fertilized females lay their eggs in spring in the nests of their larvae’s hosts. This happens near the brood-cells which have adjacent food stores. The young larvae hatch after a few days and start eating the host’s... | | |

| | The field digger wasp reaches body lengths of 7 - 14 mm. The females, are at least 11 mm in length and are thus significantly larger than the males, whose body length does not exceed 11 mm. The body size is determined primarily by the food supply during the larval p... | | |
| | The females lay their eggs in soil nests or ground nests. Either a new nest is dug, at an average depth of 30 cm, or the females look for pre-existing nests from other digger wasps. In the latter case they are not able to distinguish between already occupied and unoccupied nests, which often leads to violent clashes between them and the owners of the nest in the entrance area. The female digs a nest at which the excavate... | | |
