The larvae slip off after a few days and eat up to 1200 aphids during the two weeks of their development. The larva turns into a pupa on a leaf. After about one week the adult Asian ladybird slip off the pupa.

Soldier flies prefer forest areas. They suck on flowers, eat pollen or live off organic substances from animals. Some species live near water in which their larvae develop.
The females lay their eggs on rotting plants, aquatic plants, or on the water’ssurface.

| | | While the adults of some dung fly species prey on small insects or larvae, other types live off feces. The larvae eat parts of plants (leaves, cambium, boll) and rotting plants , or live off feces like the adults. | | |
| | Many insects play an important role in the remineralization of organic substances in soil as they decompose corpses or dead plants. Other species eat live plant parts or feed on other insects or small prey animals. Some species of insects like bees collect nectar or pollen, and thus make an important contribution to the pollination of plants. Insects can also occur as parasites, which suck bl... | | |
| | As ladybirds eat pests they are considered useful by humans. However In Europe the Subcoccinella vigintiquatuorpunctata can be harmful, especially if it occurs in alfalfa , sugar beets, clover, potatoes, carnations and dahlias. | | |
| | Elasmostethus interstinctus prefer to live in sunny habitats, where they can be found on deciduous trees and shrubs. They eat or suck out the juices from the flowers of beech, alder and hawthorn, and occasionally those of herbaceous plants near the ground.
The larvae of Elasmostethus interstinctus live from June to August. They reach their adult stage in September and ... | | |
| | Almost all spiders are land animals. They often hide during the day and are only active at dawn or at night. The water spider is the only genus which lives in water. A number of species hunt on the water surface.
Birds pose the biggest threat to spiders. However amphibians, reptiles and bats also eat spiders. Some spider species feed exclusively on other spiders. Other natural enemies are: wasps, ants, true dragonflies, small-headed flies, Nematodes and Acarina. | | |

Species which parasitise aphids can exploit up to 200 aphids in a week. The females lay their eggs on the surface of aphids. After one to two days, the larvae hatch and then eat the insides of the aphid out . They pupate in the hollowed out body of the aphid and after five days, the young adult wasps hatch. Some species specialize in spinning cocoons and live on their eggs.
Because the hatching wasps keep the populat... | | |

Bot flies reach body lengths of 10-13 mm. They are covered in thick furry hair. The mouth parts of this fly are often highly degenerated, thus many species do not eat solid food. Some species, however, take in fluid. The well developed, large wings have a central vein spreading out in different angle. The thorax is covered with scales and has a number of bristles at the rear end. Mating takes place at elevated p...
...ites). Many species choose specific animals as the host - which body orifice of the host animal is chosen for egg laying also depends on the species. The hatching maggots (larvae) develop accordingly in the nasal mucous membrane, the throat or beneath the skin (subcutis) of their host animals. Egg laying can be a risky business for some females as the larvae hatch very fast and can attack their own mothers.

...can cause panic reactions in in cattle which often sustain severe injuries by running away into fences or barbed wire. The migration and development of larvae inside the host animals inevitably leads to illness and sometimes to the host animals’ death. The larvaes’ stay in the host animals can last as long as several months. In their last larval stage the maggots leave the host animal and fall down to the soil to pupate.

| | The thick-legged hoverfly is common in almost all habitats, gardens, meadows, fields, however it is rare in forests. The females feed on pollen while the males eat nectar. The larvae (rat-tailed maggots) live in compost, manure and waste. The adult flies are active from April to September. | | |
