They have a flight radius of about 10 metres. In late autumn they begin eating intensively and continue this over a period of a few days in preparation for the winter. When the beetles have consumed enough nutrients, they bury themselves in the soil close to the food plant at a depth of several centimetres and remain there until late March or early April. Among t... | | |

The larvae hatch immediately They feed on dead organic material and algae. At the end of the larval period the males of the new generation leave the banks and fly into forests, while the females remain close to the water. | | |

Larval development usually takes 1 year, but can take up to 3 years depending on the species. During this period the larvae shed their? skin - up to 30 times. In the final stage of development the sub-imagos (pre-adults) hatch from the larvae. The sub-imagos have milky coloured wings. The sub-imagos shed their skin to become sexually mature mayflies which h... | | |
| | The comma butterfly produces 1 to 2 new generations a year. It is active in the period from May to October. The caterpillars appear from May to August. The butterflies live on forest roads, forest edges, brush (willow, hazel and elm) and in gardens, where they eat nectar preferably from gooseberry plants, hops, flowering garden plants... | | |

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 grey flesh fly is seen almost all year round. In the period from April to October, it occurs more frequently and is found in various habitats. They occur in particularly large numbers everywhere where old, rotting meat or faeces can be found. The adults often sit on trees, shrubs and herbaceous flowering pla... | | |
| | At the end of the larval period the caterpillars pupate on their host plants, where they prefer sheltered places such as niches. The pupae hang down from grass fronds near the soil. The pupae are difficult to make out on dry soil and leaf litter because of their camouflage coloura... | | |

| | ...r 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 period. The male larvae are apparently less dominant than the females when feeding. | | |

The short period of development and large number of offspring leads to a high density in the small fruit fly population, and this causes substantial losses to growing fruit as well as fruit in storage. On the other hand, the small fruit fly is of major importance in... | | |
