At the end of the third larval stage, the larvae dig down into the soil to a depth of about 2cm and pupate. After 6-9 days the adult beetles hatch from their pupae.

...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 the natural enemies of Gastrophysa viridula are insectivores and parasites. | | |
| | Egg-laying (up to several hundred eggs in a lifetime) is done with an ovipositor in moist soil orin the mud at the bottom of a body of water. The larvae reach body lengths of about 50 mm and live on plant roots, which they eat. They pupate in the soil or in rotten wood. Crane fly larvae can cause significant damage to crops. | | |
| | | ...round, amongst dead leaves, or in dung or rotting vegetation. They can even be found among the leaves of Brussels sprouts (Brassica oleracea) or white beets, especially in wet weather. The larvae feed on fungal threads (hyphae), algal cells, pollen, soil particles and substrates, which they find in excrement. They also prey on the larvae of bark beetles. They pupate in the soil. | | |
| In late March, the adult bees of the first generation hatch. The males appear first and fly back and forth over the soil nests on hot days. Mating takes place in April. Immediately afterwards, the fertilized females begin constructing the brood nest in the ground. Nest colonies form/can form, comprising several hundred - up to one thousand - individual nests in a rela...
...f May and then they die too. The larvae are left to fend for themselves until June when they pupate. In early July, the adults of the 2nd generation hatch from their pupae. They are active until September when they die. Their offspring overwinter in soil nests, hatching in March of the following year as adults of the new 1st generation. | | |
| Mating takes place in late May to early June. The fertilized females lay their eggs in moist soil. The larvae hatch after several days. Their bodies have velvety black hair. They have strong mouthparts. The larvae of Cantharis fusca live on the ground or near the ground and capture small insects, worms and snails to eat, killing them by injectin...
.... They have strong mouthparts. The larvae of Cantharis fusca live on the ground or near the ground and capture small insects, worms and snails to eat, killing them by injecting them with poison. The cold-resistant larvae overwinter under rocks or in soil litter. On sunny winter days they can be observed crawling on the snow surface. The larvae are thus also called "snow worms”. In May of the following year, they have finished the 6th larval stage and pupate. That same month, the adult beetles h... | | |
| | 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 colouration - yellowish green, later brownish-green or brown. | | |
| | ...they eat. There are two types coprophagous and necrophagous. The former feed on excrement (earth-boring dung beetles) and the latter on carrion (Silphidae).
The excretions of both species are from great importance at the remineralization of the soil. Beetles, like all living creatures, are dependent on water. There are species that live under or near the water like hygrophiles or predaceous diving beetles.
Depending on which species they are, beetles fly shorter or longer distances. There ar... | | |

When the labor force hatches the nest expands to accommodate up to 500 bumblebees. Nests in soil can have a depth of 1.5 metres. Bombus terrestris live from March to October and are found in forests, on meadow slopes, and in gardens or fields. They can be encountered from the lowlands to the mountains. The workers of the Bombus terrestris pr... | | |
| | ...sychoda phalaenoides prefer to lay their eggs near faeces or urine. The larvae are slender and have a body length of up to 4 mm. They have a very distinctive head shape. The larvae of Moth flies live in a variety of habitats such as water, forest soil, moss, fungi or in heavily polluted water (i.e. drains, sewage treatment plants).

The larvae live in soil, some also in water. The larval phase ( in total 3 stages) lasts for about 8 days. In Europe the adult flies take 2 to 3 weeks to hatch. The high reproduction rate of Muscidae (about 8 generations per year), is due to the large number of enemies t... | | |
