Adult robber flies’ ways of living are as varied as their biodiversity. Robber flies can be encountered in different habitats, from forests to sandy areas.
Less is known about their larvae They live in soil or in the woods and, like the adult flies, feed on other insects and their larvae (mainly on scarab beetles’ larvae, or on the larvae of beetles which live in wood). The larval stage takes 1-2 years before the larvae pupate.
Adult robber flies ambush other insects in flight. For this purpose they perch and wait. . If an insect is flying in their vicinity, the robber fly flies up into the air, attacks and ... | | |
| | Both males and females overwinter. In spring they mate. When it is time to lay eggs the female gnaws a tunnel into dead wood, up to 30 cm in length. At the end of the tunnel is a cell which is approximately 2.5 cm wide ; the female brings pollen and nectar here and lays an egg. She then seals the cell with chippings which she glues together with her saliva. In the dire... | | |
| | | In spring, a nest is founded by a young queen. The nest is made from wood, which is taken from dry or rotten plant stems, chewed and then bonded with saliva. The nests are often found in buildings, garages, sheds or blindboxes. When finished, nests consist of about 50 cells. They have no protective outer surface. Up to 30... | | |
| | The young ants overwinter twice in the nest which is built in the dead wood of trees and located up to three metres in height. The major part of the nest is under the soil. Some nests are only in the ground. After reaching sexual maturity, the young ants swarm from the nests on warm afternoons in May and June New colonies... | | |
| | Common woodlouse | The common woodlouse (Oniscus Asellus), belongs to the order isopods (Isopoda), the family Oniscidae and the genus Oniscus. This species is commonly found in Europe, America, Africa and Asia. Common woodlice reach body lengths of 15-18 mm. They are dark grey to blackish-brown in colour. They have two longitudinal rows of bright spots on their backs and bright coloured. appendages with punctiform openings (defensive glands) on their sides. They h...

The common woodlouse lives among fallen leaves, in rotting wood, under stones and under the surface layer of medium moist soil in deciduous forests and bushes. It is also found in cellars, gardens, stables, greenhouses and compost heaps. An adequate level of humidity is important, since their gills can only a...
...t soil in deciduous forests and bushes. It is also found in cellars, gardens, stables, greenhouses and compost heaps. An adequate level of humidity is important, since their gills can only absorb oxygen, when combined with a film of water. Common woodlice are active during both day and night, but prefer the darkness. They feed on plants, fruits and vegetables. Woodlice are preyed on by a variety of birds.
Adult woodlice have a life expectancy of up to 2 years. They reproduce with the onset of warmer weather. The females produce 10-70 young, up to 3 times a year. These are 2-3mm in length. The females retain the fertilized eggs in pouches. These pouches are ...
...ales produce 10-70 young, up to 3 times a year. These are 2-3mm in length. The females retain the fertilized eggs in pouches. These pouches are situated on the legs and are filled with water. The young develop in these pouches and leave as small woodlice. Further brood care is not necessary. About 3 months later, the young woodlice become adults and shed their skin for a living. The adults overwinter in the soil. | | |
| | Their larvae are up to 120 mm in length. The larvae prefer to live in and feed on rotting wood and develop in oak forests or in places where other plant material rots. During their development (3 to 5 years) they profit from the warmth created by the decomposition of the plant material. The mature larvae pupate in a cavity approximately the s... | | |
| | Phaonia subventa prefer to live in forests. They are active from April to winter. They reproduce several times a year. Females lay their eggs in rotting leaves, rotting wood or in carrion, on which their larvae feed. The larvae overwinter there. | | |
| | ...emales of many species have a long ovipositor. The abdomen is clearly separated from the front part of the body.
Ichneumon wasps are widespread in various habitats such as mixed forests, deciduous forests, coniferous forests, fields, wetlands, wood shots, clearings and forest deadfall.
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... | | |
