The upper surface of the thorax (chest) is a dusty whitish-grey. The females have, in addition, narrow brown stripes. The femurs of the males are black and the females’ are yellow on the 2nd and 3rd pair of legs. The lower legs are yellow in both sexes. | | |
| ...is 25-35 mm in length, the female workers, 15-25 mm, and the drones 20-30 mm. The crown of the head and the cheeks are a reddish-copper colou. The face is without markings. While the antennae of the drones comprises 13 segments, those of the females have only 12 segments. The eyes of the hornet are clearly visible and appear in the shape of a "C". The thorax and abdomen of european hornets are hairy. The upper surface of the chest (thorax) of the subspecies Vespa crabro crabro is da...
...le the subspecies Vespa crabro germana have a narrow red marking shaped like a "V" on their Mesoscutum. The abdomen has the typical black-brown/yellow colouration of wasps, and comprises 7 segments in the drones, 6 segments in the females. which besides is fitted with with 2 numbers of similar dripped designs, The females have a poisonous sting at the end of their abdomens; the drones lack this sting but have, in its place, sex organs. The wings of the european hornet are reddish-orange in colour. A characteristic feature of this insect (apart from the body size) is... | | |
| In late March, the adult bees of the first generation hatch. The males appear first and fly back and forth over the soil nests on hot days. Mating takes place in April. Immediately afterwards, the fertilized females begin constructing the brood nest in the ground. Nest colonies form/can form, comprising several hundred - up to one thousand - individual nests in a relatively small area. The nests consist of a 160 - 230 mm long main passageway, which can be conne...
... hundred - up to one thousand - individual nests in a relatively small area. The nests consist of a 160 - 230 mm long main passageway, which can be connected to individual brood chambers. The brood chambers are filled with food for the larvae by the females, a single egg is deposited on the food and the brood chambers are closed. Shortly after hatching, the larvae of the 2nd generation start feeding on the food supply. They develop in their chamber. Approximately 3 weeks after mating the males die. The...
... a single egg is deposited on the food and the brood chambers are closed. Shortly after hatching, the larvae of the 2nd generation start feeding on the food supply. They develop in their chamber. Approximately 3 weeks after mating the males die. The females care for their brood until the end of May and then they die too. The larvae are left to fend for themselves until June when they pupate. In early July, the adults of the 2nd generation hatch from their pupae. They are active until September when the... | | |
| After mating, the females lay their eggs, 2-4 mm in length (depending on the species, inside scarab or weevil larvae. The host larva is stung in the neck or chest area and is repeatedly kneaded with the mouth parts (mandibles). The females then build tunnels in the earth, sometimes to a depth of one metre beneath the surface of the soil, and drag the permanently paralyzed host larvae into these, depositing them at the end. The host larva are thus stowed in an "incubator". On...
...of the soil, and drag the permanently paralyzed host larvae into these, depositing them at the end. The host larva are thus stowed in an "incubator". One egg is placed on each host insect. During a period of one to three months, Scoliidae females can lay 50 or more eggs. After egg laying the female leaves the tunnel. | | |
| | Philodromus aureolus have a flat body. The females have a yellow-brown, golden brown or dark brown base colour. The males are dark brown with a faint light pattern although their colouration is mostly obscured by dense hair. The females are 4-7 mm in length, the males 3. 5 - 5 mm. The hair of the males is dazzlingly bright (iridescent), with a green metallic sheen which varies in intensity. The females have a strip of light-coloured hair running lengthwise along their backs. | | |
| | Bibionidae | | ...e are dark , very hairy and resemble Diptera. They have large, evenly structured antennae on their heads. The males are very large, and have compound eyes of various dimensions on the upper side of the head which is hairy (the face too), while the females are smaller and hairless. The females have a spike to dig with on their forelegs. The colour of the male and female Bibionidae is different, the male being black and the female being reddish brown to amber. In spring and autumn Bibionidae often swarm en masse. They do not sting and t... | | |
| | Moth flies usually feed on plant juices or nectar, however some species do not eat at all. The females of the genus Sycorax sting frogs and suck their blood. The tropical Sand flies are known to tranmsit diseases. As moth flies are not good flyers , their move often is completed by the wind, but with very good control.
The females often lay their eggs (individually or as a clutch) close to water. The Psychoda phalaenoides prefer to lay their eggs near faeces or urine. The larvae are slender and have a body length of up to 4 mm. They have a very distinctive head shape. The l... | | |
| | Wool Carder Bee / Leafcutting Bee (Anthidium manicatum) | ...y. Female Anthidium manicatum are 11 to 12 mm in length.
The Anthidium manicatum lives on nectar and pollen, which it collects from plants such as Stachys, sage or motherwort. It nests in pre-existing holes in earth, masonry or wood. The females build individual cells for their eggs using pieces of leaves bound together by a substance they secrete. They then supply each cell with pollen or nectar, before introducing an egg into the cell. After egg-laying the cell is sealed. When the l...
...l with pollen or nectar, before introducing an egg into the cell. After egg-laying the cell is sealed. When the larvae hatch, they live on the pollen and nectar for weeks before pupating. The Anthidium manicatum reproduces once a year. The females are active from June to October, the males from June to September. On rainy days the animals take refuge in safe, waterproof cavities.

| | Armadillium (Pill woodlice) | | ...vulgare) is a woodlouse and belongs to the family Ligiamorpha.
This isopod can reach a length of up to 16 mm and is able to roll itself up into a ball. While the males are predominantly a uniform blue-grey , black-grey or brownish-grey, , the females have bright spots. The surface of the armadillium is smooth. The armadillium has a high resistance to water shortages. Therefore, it is also found in forest edges and ruderal on plants growing on waste ground or among refuse.
The females breed up to 3 times a year. Depending on the size of the female, from 20 to 160 young isopods hatch.

| | Horse flies | | ...e flies worldwide. Some examples of these species are: twin-lobed deerfly (Chrysops relictus), pale giant horsefly (abanus bovinus), band-eyed brown horsefly (Tabanus bromius), Tabanus sudeticus and notch-horned cleg (Haematopota pluvialis).
The females are drawn to humans and mammals by the smell of their sweat. They feed on their blood, sucking up to 0.2 ml from them. The males feed on nectar. In some species the females live off plants and carrion.
The bite of a horse fly can penetrate clothing and is much more painful than the sting of a mosquito due to the larger mouth parts. Horse flies are considered a risk to humans and animals, especially in Africa, as... | | |
