| ...n contrast to that of insects varies widely. Their body growth is greatly limited by a rigid exoskeleton. Arachnids moult, after retreating into hiding and fasting. While most spiders moult hanging down from a thread (thread moulting) to spend the time of moulting on their backs. | | |
| | ... majority of bumblebees are workers who live beside the male drones and young queens. In Europe bumblebees survive only one summer. Drones and workers have a life expectancy of 3 to 4 weeks, while a queen lives for approximately 1 year, during which time it hibernates for 8 months. There are, among bumblebees, socially parasitic species (Cuckoo bumblebees) which leave their eggs in the nests of fellows and let the fellows care for their breed. The larvae of the cuckoo bumblebees danger the fellows’ ... | | |
| | | The common wasp is found in almost every kind of landscape. In areas inhabited by humans, wasps are considered a nuisance in autumn time. The venom of the wasp may cause allergic reactions. When wasps sting hormones are released and this can encourage other wasps to sting. Due to this a large swarm of this kind of wasp poses a great danger to humans. | | |
| | 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 w... | | |

Blow-flies usually lay their eggs (up to several hundred at one time) in strongly smelling organic substances such as feces or carrion. The excretions of the larvae can be problematic for humans. therefore meat which has been in contact with them should not be eaten. Due to the fact that they carry germs, blow f... | | |

After the Queen has laid her eggs she looks after them for some time until the workers hatch , then they care for the brood. Later they also expand the nest above ground. The queens, who can live up to the age of 29 , lay several thousand eggs in their lifetime. After 14 days the larvae hatch . The larvae pupate after 2 weeks. After a month the adult ants hatch. | | |
| | In contrast to spiders the head, chest and abdomen form one unit. Harvestmen have neither spinning glands nor poison glands. Like all arachnids they have 8 legs, which in many species are very long and can reach up to 25 times the actual body length. If the Harvestmen is attacked, it can separate from one leg, this misleads its attacker , encouraging it to continue moving away and later is restored. This leg grows back over the course of time. | | |
| | The German wasp is found in almost every kind of landscape and can be an annoyance to humans at autumn time. Its favorite environments are forest edges with high bushes and perennials. | | |
| | 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 their winter habitats for next year. In extreme cases, several hundred thousand can gather. In spring, after overwintering, ... | | |

The brown legs to the ankle are much thicker in the upper section of the rear pair, with which the willow flea can jump very far (up to hundred times its own body length).
The life expectancy of the adult beetle is 8-9 months. They are usually found in the countryside, moist forests, forest edges, wet meadows, marshes, meadows and heathland are their preferred habitats. They can also be ...
...rest edges, wet meadows, marshes, meadows and heathland are their preferred habitats. They can also be encountered in natural gardens and parks.
The willow flea beetle is active during the day from May-October (after overwintering). During this time it is mainly seen on willows and poplars, whose leaves it eats. The willow flea beetle nibbles roundish holes into the leaves.
At age 7-8 months, the willow flea beetle is sexually mature. In June/August the beetles mate. The fertilized f... | | |
