| ...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 they have - and not due to a dramatic increase in their numbers.
A number of species (outside Europe) are known to transmit diseases such as dysentery, cholera, hepatitis, polio, anthrax, typhoid fever or sleeping sickness. | | |
| | It is characteristic of the ladybird to have symmetrical spots on the wing covers. The color of these spots can be black, bright red, or brown. The number of spots varies. There are species with 2, 4, 5, 7, 10, 11, 13, 14, 16, 17, 18, 19, 22 and 24 spots. Furthermore the number of spots within a species can also vary. | | |
| | | Bees | | The term "bee" (Apiformes) is used for several families in the order Hymenoptera. When people speak of ‘bees’ they tend to mean honey bees and yet it is estimated that bee species number approximately 20,000 in total, 700 of which can be found in Europe. In Germany there are about 500 species of bees. The oldest bee fossils date back to 80 million years ago.
The body of the bee - as normally is the case with all insects - comp... | | |

The number of Geotrupes stercorarius is declining. | | |
| | Isopods | | ...ecies globally, which are divided into approximately 120 families, some examples of which are the Common rough woodlouse, the waterlouse and the Giant isopod.
Isopods can reach lengths of 3 to 12 mm. The body is flattened. They have a constant number of body limbs and 7 legs. At the rear legs are gills. Isopods also live in fresh water. Although woodlice no longer live in water they still have gills. Under the body of the female isopod, there is a breast pocket, where the young (up to 100 per ye... | | |
| | Asian ladybird feed on large quantities of aphids (from 100 to 270 per day), but also feed on other insects, eggs and larvae.
The Asian ladybird secretes a yellow, bitter poison (hemolymph) when in danger , which significantly reduces the number of its enemies. | | |
| | Due to the damage they can cause to wooden structures, food supplies, crops or ornamental plants, a number of insects are regarded as pests. These include the blood-sucking insects. | | |
| | The life span of Brachycera is often only a number of days or weeks , with the larvae stage occupying most of that period . The adults of Brachycera are active in Central Europe from April to October. During the winter the animals (in all stages of development) live in safe habitats. | | |
| | 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 dragonfl... | | |
| | Orthoptera differ from other insects in the following ways: they have 2 pairs of wings, biting and chewing mouth parts , 3 simple eyes as well as compound eyes , a number of different wire-like sensors, a saddle-like Pronotum, hind legs which make them capable to jump, organs for the production and perception of sound and 11 segments of the abdomen with an ovipositor on the female abdomen .
