Order of the insects that belong to the beneficials count in the fight against vine pests. But they are also pests, because they like to take vegetable food. The best known species is the common earwig (Forficula auricularia). The development takes place via a whitish, oval egg over four to five larval stages up to the sex animals. The male is 10 to 16, the female 9 to 14 millimeters in size.
The chestnut animals are armored and have powerful tongs at the body end, which serve to catch the prey and to capture the female buttock during mating. The hibernation takes place as an adult animal in the soil, in which already about 60 eggs are laid by each female in the winter to spring. Even after the hatching of the larvae they are still supplied with food. The foraging of adult animals takes place at night. It will aphids and small ones tracked consumed. But also soft or ripe fruits (among other grapes), as well leaves. shoot tips and flower parts be bitten and sucked. A detectable, negative influence on the crop in the vineyard on a larger scale, however, is extremely rare. See also below Vine enemies,
