| | 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. | | |
| | ...r surface? of their chest (thorax) is shiny black. Their scutellum is also light yellow. They have markings on the upper surface. The females have an ovipositor on the end of their bodies.
The adult flies have a life span of about 1 week and only feed on vegetables (phytophagous). Aside from the open air, they are mainly encountered in greenhouses. After hatching from pupae, the females start feeding immediately. They drill small holes in the top surface of plants’ leaves using their ovipositors and suck up liquid with their mouth parts. The damaged areas on the leaf tissue (which also enable bacteria and fungi to penetrate into the plant...
... miner larvae, for example, the larvae of the ichneumon wasps Dacnusa sibirica and Diglyphus isaea. The ichneumon wasps lay their eggs in the larvae of the Chrysanthemum leaf miner. The hatching wasp larvae cause mass deaths of the host larvae by feeding on their insides. Amongst humans, the Chrysanthemum leaf miner ( is regarded as a pest when encountered in greenhouses and plantations, especially en masse as they can cause significant damage and crop yield losses. Pesticides are of little use... | | |
| | Green long-legged flies prefer to be in the vicinity of small rivers, streams and ponds. They feed on honeydew, which they find on the leaves of plants, but they mainly survive by preying on worms, small insects and their larvae. | | |
| | The females lay their eggs on rotting plants, under bark or in reeds, using a special ovipositor which enables them to bore holes. After hatching, the larvae feed initially on the surrounding plant substrates. In a later stage of their development they prey on small insects, just as the adultsdo. After the last larval stage, the larvae pupate. The pupae are spun in a cocoon of silk and have long breathi... | | |
| They also feed on dung heaps and carcasses to obtain protein and minerals. 30 000 to 50 000 flies can be encountered at the same time, especially in autumn when they gather to overwinter and to mark their mating spots with special scents in the vicinity of thei...
...lly then visit dung-heaps where they await females for mating. The mating takes place at another location later on.
The female flies lay their eggs on dung-heaps or compost heaps. From the first or second day after hatching, the larvae begin feeding on feces or rotting parts of plants. At the end of their third larval stage the fully developed larvae turn into pupae. This happens in the dung or compost or in the soil below it. From egg to adult fly can take 14 to 32 days.

| | The females possess special glands to produce fibres which they use to build cocoons under water. Air is kept in these cocoons for the larvae to breathe. Water scavenger beetles feed on plants and rotting substances. Their larvae mostly live predatorily at the bottom of water bodies. Water scavenger beetles are very useful because they purify the water. | | |
| | ... mating, the oviposition of the females happens in cocoons near the surface of water where the eggs are glued to water plants. Approximately 8-10 days later the larvae (with body lengths of 3-4 mm) hatch. They increase rapidly in size . The larvae feed (starting at the lastest three days after hatching) ) on smaller aquatic animals, and are even prone to cannibalism. In water they catch floating prey with their clamp-like mouthparts (mandibles), hold them tight and swim with the living prey intac... | | |
| | ... their appearance, Chrysolina Polita can be confused with poplar leaf beetles (Chrysomela populi). Chrysolina Polita are encountered from March to October in different habitats, up to subalpine altitiudes. . Both the adult beetles and the larvae feed on the leaves of various plants, such as mint (water mint, cat mint), sage, or oregano.

| | .... They bite the butterfly pupa and lay an unfertilised egg inside it. From this egg a male develops. If the females find a large pupa, they insert a fertilized egg in the same manner, from which a female develops. The hatched larvae initially feed on the blood of the butterfly pupae.
Later, they eat the whole insides of the pupae. After that the black slip wasp larvae pupate. 2 weeks later the young black slip wasps hatch and bite through the skin of the butterfly pupae. The adult black... | | |
