| Insects (Insecta) | | Insects (Insecta) live almost everywhere on Earth. They are highly specialized and there are about 30 million different species. Insects can have body sizes from 0. 2 to 330 millimeters. What is common to all insects is the highly visible breakdown of the body into three parts: head, chest and abdomen; and the presence of three pairs of legs. | | |
| | Excretions of other insects (honeydew of lice), nectar, seeds, fruit or pollen, in addition to many parts of plants also form part of their diet. Driver ants prey on other insects and animals. Some species are scavengers and feed on the excreta of other insects. Others collect seeds, grow mushrooms or dig tunnels into the nests of other insects to steal their breeds and to feed on them. | | |
| | | Many insects play an important role in the remineralization of organic substances in soil as they decompose corpses or dead plants. Other species eat live plant parts or feed on other insects or small prey animals. Some species of insects like bees collect nectar or pollen, and thus make an important contribution to the pollination of plants. Insects can also occur as parasites, which suck blood or develop into adults in living tissue. | | |
| | Chrysoperla camea s. l. | Chrysoperla camea s. l. belong to the net-winged insects and are family members of the Green lacewings. They can be found throughout the world except in Australia and are encountered at almost every topographical height.
Chrysoperla camea s. l. reach wing spans of between 15 and 30 mm. Their bodies ar...
...ir bodies are long, slender and green in colour. Their wings have thick veins. They have compound eyes which glitter and are bright and clear. Some types turn brown before the winter. Chrysoperla camea s. l. reproduce several times a year. The adult insects are usually active at twilight and feed on pollen, nectar and honeydew from aphids. During the day they sit, hidden, under leaves. They overwinter in places where they are well hidden from other animals and insects. Their larvae are considered beneficial as they eat aphids (up to 10 per day) and aphids are viewed as pests in agriculture. In 1999, the Chrysoperla camea s. l. was declared Insect of the year. | | |
| | The individual body segments of insects are solid and are protected with plates of Chitin (back, abdomen and side plates). Insects breathe with the help of tracheae, in addition to various glands in the spaces between these plates. Insects sense their environment with their facet eyes, antenna and sensors, which register heat, humidity, shock and vibration. | | |
| | Earwigs (Dermaptera) | The earwigs (Dermaptera) are an order of insects. They belong to the winged insects (Pterygota). Approximately 1, 800 species of earwigs are known worldwide, 8 of which occur in Germany. Some examples include: tawny earwig (Labidura riparia), common earwig (Forficula auricularia), Titanolabis colossa, ringlegged earwig (Euborellia ...
...common earwig (Forficula auricularia), Titanolabis colossa, ringlegged earwig (Euborellia annulipes), Apterygida media, Chelidurella acanthopygia, Anechura bipunctata and Labia minor. The name "earwig" derives from the earlier use of these insects (in powdered form) in the treatment of ear diseases. | | |
| | A special group within the species are insects which build states, such as termites and Hymenoptera. Fossil evidence from insects has been found, dating back as far as 350 million years. Some fossils are even older. | | |
| | Forest bug feed by sucking out the insides of fruit. They occasionally kill other insects and suck dead other arthropods (insects, arachnids, crustaceans etc). After mating, the females lay their eggs on top of a leaf. The larvae overwinter - unlike those of other kinds of shield bugs - under the bark of trees, and their further development takes place on broad-leaved trees. | | |
| | Bombus pascuorum | | Bombus pascuorum is a very common bumblebee. It is one of the colony building insects. The head, chest and back are brown in colour with the abdomen of some insects being bright or dark. The queens reach a body length of up to 22 mm, and the drones, up to 18 mm while the workers are considerably smaller. The Bombus pascuorum can be found in meadows and clover fields, but also in walls and buildings. It feeds... | | |
| | Panorpidae (as all Scorpionflies) prefer shady areas in summer. They are often encountered in bushes and shrubs. They live on dead or injured insects and some species also eat nectar, fruit or the honeydew of aphids. Some also prey on insects trapped in spiders’ webs. | | |
