This is done near the water’s edge, in the presence of the males who keep watch. After oviposition the females are guided back to the riparian vegetation by the males, and mating occurs again. The grip of the female on the male is so strong during mating that the blue wax layer at the end of the male’s abdomen dissolves and the tip turns black. | | |

Meat that has come into contact with such flies should never be consumed by people, for the oviposition of flies carry various pathogens into food. The metabolic products of the maggots are also dangerous. | | |
| | | 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. | | |
| | After mating, fertilized Cerceris quadrifasciata females dig tunnels in the ground for oviposition. They then capture insects on which they lay their eggs. The hatched larvae feed immediately on the live and stunned insects which are brought in constantly by the females. | | |

Firstly through ingestion of their eggs, secondly through oviposition directly on the host animal, or thirdly through the hatched larvae’s direct entry into the host animal. Usually the host animals die before the larvae’s development is complete. The pupation of the larvae usually occurs outside the host animal.

| | Melanostoma mellinum produce two new generations a year. The first is active from April or May, the second from September or October. The females of the first generation lay their eggs in late May, and the females of the second generation do the oviposition in early August on the food plants of the larvae. The larvae are initially blind. They prey on aphids, flies and other soft-skinned insects. After 2 months, they pupate and shortly thereafter emerge as adults. | | |

Pachygnatha listeri often appear in the company of Pachygnatha clercki and in the vicinity of Zygielle x-notata.
Mating may take several hours and is normally non-fatal for the males. For oviposition, the female produces a flat, white cocoon, which it fastens amongst moss, under a stone or under dry leaves. There is no brood care. The newly hatched spiders can be found just above the ground. They catch prey with small orb-webs that they build. I... | | |
