Their most striking characteristic is their long, segmented antennae, which often point backwards and may exceed the length of the body. They resemble ibex horns hence this insects name. As the antennae are so long, they must be anchored stably to the head which leaves little space for the eyes. In many species therefore, the eyes grow around the base of the antennae from behind. The bodies of these insects are elongated and are often larger in the males. Although sometimes the opposite is true. | | |
| | Cleridae fly and run well. They are present on different flowering plants or on tree bark, where they prey on other insects or their larvae. Female Cleridae (depending on species) lay 28 to 42 eggs under tree bark. The hatched larvae also prey on other insects. | | |
| | ...hers choose fungus, rotting plants, healthy plants and faeces, some only for oviposition. The Silphidae and their larvae live and feed on carrion - necrophagous, on parts of plants - phytophagous, on faeces - coprophagous, or by preying on adult insects, insects’ larvae or on snails. Dendroxena quadrimaculata live off caterpillars, while members of the genus Nicrophorus bury the corpses of small animals (mice, moles etc.) and dig an incubator for oviposition alongside them. The females form small balls out... | | |
| | ...weavers livein different habitats in Central Europe. They can be found on dry grass and ruderal vegetation, on trees, shrubs, perennials or inflorescences of dry plants. They also like to be in areas populated by humans. The meshweb weavers live off insects. Often, these are medium to large sized flying insects, which get caught in their finely spun webs. | | |
| | After mating, fertilized Cerceris quadrifasciata females dig tunnels in the ground for oviposition. They then capture insects on which they lay their eggs. The hatched larvae feed immediately on the live and stunned insects which are brought in constantly by the females. | | |
| | Ants | | Ants (Formicidae), a family within the order Hymenoptera, are among the colony building insects and are found almost everywhere in the world, but are especially common in the tropics. From the 12,500 species that are known, 180 can be found in Europe. In Germany, the Red forest ant and the Black garden ant are the best known ant species.... | | |
| | Bees | | ... 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 - comprises three parts: head, chest, abdomen. The facial features include - eyes, two sensors which serve as a nose, mouth and mouth parts comprising two strong mandibles (jaws) and a proboscis. There are two pairs of thin wings and six legs a... | | |
| | Lepidopterans - Moths and Butterflies | | The lepidopterans (Lepidoptera), also known as moths and butterflies, represent the most species-rich order of insects. So far, 180,000 species, in 127 families, have been documented , and about 700 new species are discovered every year. Apart from in the Antarctic, moths and butterflies are found worldwide. In Germany, for example, there are about 3700 species. | | |
| | The life span of arachnids, in 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 back... | | |
| | Common to all wasps is the black-and-yellow warning colour of the body. The Vespinae live in states or parasitically as so called cuckoo wasps. Adult Vespinae mainly feed on small parts of dead or living animals, from insects, pollen, plant juices and from nectars. Their larvae are mainly fed on animal meat.
