They themselves feed on tree sap , plant juices, nectar, fruits o... | | |
| After mating, the fertilized females lay their eggs in the nests of different bee and waspspecies, for example Heriades truncorum and Ancistrocerustrifasciatus. Occasionally, oviposition takes place in butterfly cocoons, as observed in the case of the small tortoiseshell (Nymphalis urticae). Usually one egg is ...
...bee and waspspecies, for example Heriades truncorum and Ancistrocerustrifasciatus. Occasionally, oviposition takes place in butterfly cocoons, as observed in the case of the small tortoiseshell (Nymphalis urticae). Usually one egg is placed in each nest. Egg-laying often takes place in the nests of solitary bees of the genera Hylaeus and Osmia. A few days later the larvae hatch from their eggs. Firstly they eat the eggs or larvae of the host animals and later on any food supplies found there. | | |

When the larvae hatch they feed on the pollen and nectar until they pupate. The adult bees hatch in late summer and leave the nest for the first time the following spring. However, there are species that spawn two generations within one year. | | |
| | The female digs a course in the soil for her eggs. At the end of the tunnel is a chamber which houses the egg and a stunned insect that will later serve as food for the hatched larvae. After oviposition, the nest is sealed and the entrance camouflaged. | | |

The mouthparts (mandibles) of the females are elongated and have a tooth-like appendage, to capture prey and facilitate their transport to the nest. Different species of the genus Cerceris can be recognised by the shape of their mouthparts. The abdominal segments are strongly constricted at the nodes so that the abdomen appears to have a strongly undulating surface. | | |
| After completion of the nests, the eggs are laid, one in each breeding cell. After 2-3 days the white maggot-like larvae hatch, and are fed with captured honey bees by the mother. The female larvae clearly receive greater consideration than the males. The larvae live inside the...
...y receive greater consideration than the males. The larvae live inside the body of the bees. After each flight for new supplies of bees the mother bee wolf seals the entrance to the tunnel, to protect the larvae from intruders (eg beetles). When the nest is located on steep slopes, however, the entrances stay open. About a week after hatching, the larvae spin a bottle-shaped cocoon, in which they pupate. | | |
| | Hedychrum rutilans ichneumous lives off bee wolf larvae. Female Hedychrum rutilans lay their eggs on the mother bee wolf or on the prey she’s carrying and in this way the Hedychrum rutilans larvae gain access to the bee wolf’s nest. Bee wolf larvae overwinter as pupae and hatch as adults in June of the following year. | | |
| 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 ...
...r 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. | | |
