| Both males and females overwinter. In spring they mate. When it is time to lay eggs the female gnaws a tunnel into dead wood, up to 30 cm in length. At the end of the tunnel is a cell which is approximately 2.5 cm wide ; the female brings pollen and nectar here and lays an egg. She then seals the cell with chippings which she glues together with her saliva. In the direction of the exit the female then builds a new c... | | |

There are species which live from feces and others which tunnel into plants, eating from their substance.
The larvae live in soil, some also in water. The larval phase ( in total 3 stages) lasts for about 8 days. In Europe the adult flies take 2 to 3 weeks to hatch. The high reproduction rate of Muscidae (a... | | |

The beetle prefers to live in forests. The adults fly at night close to the ground making a loud humming sound. In the spring males and females dig a 40 cm long underground tunnel for mating, which leads into several chambers, which can be reached through temporary tunnels. In the chambers, balls of dung are placed before the larvae as a future food supply. The side passages to the chambers are then filled with feces and sealed with clay. The larvae need approximately 1 year to grow up and then to turn into pupae.

| ...ter mating, the females lay their eggs, 2-4 mm in length (depending on the species, inside scarab or weevil larvae. The host larva is stung in the neck or chest area and is repeatedly kneaded with the mouth parts (mandibles). The females then build tunnels in the earth, sometimes to a depth of one metre beneath the surface of the soil, and drag the permanently paralyzed host larvae into these, depositing them at the end. The host larva are thus stowed in an "incubator". One egg is placed o...
...epositing them at the end. The host larva are thus stowed in an "incubator". One egg is placed on each host insect. During a period of one to three months, Scoliidae females can lay 50 or more eggs. After egg laying the female leaves the tunnel. | | |
| | 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 females dig tube-like tunnels for their eggs, into the ground in sandy slopes, roads, embankments, or even in the sandy joints between sidewalk slabs. The tunnels are 1 - 1. 5 metres in length. At the end are 5 - 7 (sometimes even more) chambers the size of pigeon eggs, which house the brood and their food. The jaws of the bee wolf are particularly robust and strongly built (is this related to the tunnel digging. They also have strong, solid spikes on their front feet which are helpful for digging. | | |

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. | | |
