| ...agged edges like those on stamps, while their larvae feed on the roots of the plants. The leaflets can be completely bitten through (blue lupine). Small and bird's-foot broom are also eaten by Sitona gressorius. In June, the young beetles of the new generation hatch. They often enter residential areas, occurring in houses to such an extent that they constitute a plague. | | |

| The sage leafhopper reproduces several times in the course of a year. The females lay their eggs on the food plants of the nymphs. The last generation of the year overwinter as eggs. Sage leafhoppers can be observed from May to late autumn. The adults are shy and fly away rapidly when disturbed. Among the natural enemies of the nymphs of sage leafhoppers are: assassin bugs, lacewings and tiny nema... | | |

| ...reates several white, round cocoons onthe branches or the bark of trees for the protection of the eggs. Up to 100 yellow eggs are laid in these cocoons. A few days later the female autumn spider dies. The eggs overwinter in the cocoon. The new generation hatches in spring.
Some natural enemies of the autumn spider are: insectivores, birds and other spiders from the family pirate spiders (Mimetidae), for example species of the genus Ero. | | |

| ...wo days later. The larvae go through 3 stages of development before they pupate. Pupation takes place in the nutrient medium or in the underlying soil. The pupae have a reddish surface. 14-32 days after the eggs are laid, the adult flies of the new generation leave their pupae.
Sepsis violacea are of ecological importance as they clean the soil. | | |

| ...k brown bristles at the edges and in the middle. Their glands are dark brown and without hair. Their legs (3 pairs) are glossy dark brown to black. A few weeks after hatching, the larvae pupate on their food plants. One to two weeks later, the new generation of beetles hatch. Brassy willow beetles overwinter in the soil as adults.

| ...rface by scraping them off. The development of the larvae is complete in 3 weeks (June/July). They pupate in oval spaces in the earth just beneath the surface of the soil, where they remain for 8 to 11 days. In August the beetles of the new generation leave their pupae. | | |
|
| The nettle-tap moth is diurnal. The first generation are active from early May to early July and the second from late July to early October. These moths are found in all habitats where nettles (Urtica) especially Urtica dioica, grow. The caterpillars of the nettle-tap moth reach body lengths of abo... | | |

| The mating season of the beetles is from spring to autumn and begins with copulation among the autumn generation of beetles from the previous year, which happens immediately after its release in March / April. Egg laying takes place in several sessions on the food plants of the larvae. The females attach each of the 100 to 600 oval, light to egg yolkyellow... | | |

| ...gths of 4-5 mm. Their yellow to brown bodies are shaped like isopods and have appendages of different sizes according to what species they are. The larvae of flat-footed flies pupate at the end of the last larval stage, in or on the soil. The second generation overwinters in the larval stage. | | |

| ...gust in the mountains as well as in the lowlands. Egg laying takes place in ponds, pools, puddles, canals and ditches. 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. | | |
