The antennae of most species have more than 16 segments. The presence and shape of the areole in the front wings is a major identifying characteristic. The females of many species have a long ovipositor. The abdomen is clearly separated from the front part of the body.

...umon wasps are widespread in various habitats such as mixed forests, deciduous forests, coniferous forests, fields, wetlands, wood shots, clearings and forest deadfall.
Species which parasitise aphids can exploit up to 200 aphids in a week. The females lay their eggs on the surface of aphids. After one to two days, the larvae hatch and then eat the insides of the aphid out . They pupate in the hollowed out body of the aphid and after five days, the young adult wasps hatch. Some species speciali... | | |

It is typical for all Hylaeus to have a clearly visible marking on their face, yellow or yellowish white in colour, but on the females this may be reduced to a few points at the sides or to narrow vertical stripes on the anterior eye margins , or this marking can be completely absent. The markings on the face vary from species to species, and this therefore allows accurat...
...ceae), dicots (Resedaceae), rose plants (Rosaceae), tansy (Tanacetum vulgare), feverfew (Tanacetum parthenium), golden marguerite (Anthemis tinctoria) and yarrow (Achillea millefolium).
Hylaeus reproduce either once or several times a year. The females lay their eggs in nests, which are constructed in hollow plant stems, dead wood or often in the galleries of beetles or other insects. After oviposition (egg laying) the nest is sealed. The larvae overwinter in the nests. Wasps of the family G... | | |

The females lay their eggs in the nostrils or eyes of sheep. The larvae hatch from their eggs inside the females and are shot into the host animals in drops of liquid. The host animals resist this. The laying of the maggots must be done quickly, otherwise the mother will be attacked by her own brood. The larvae, approximately 500 in number, nest in the n... | | |
| | Twin-spot centurion soldierflies reach body lengths of 11-13 mm. Their bodies are very slender and shiny. The abdomen of the females is red at the sides and (in the shape of a lance) leads backwards. The abdomen of the male is narrow, rounded at the end and dark purple in colour. The legs of the females are yellow, while those of the males are dark. | | |
| | Although Thomisus onustus are a species of Araneomorphae, they do not catch prey in webs but ambush them on the flowers of solitaire growing plants. In Central Europe, these plants include Berteroa incana and heather (Erica). Here, the females are so well camouflaged that their prey run into them unawares. Males and females grab their prey - hover flies, bees, wasps, butterflies or small beetles, often considerably larger than the spider itself - with a snap of their front legs and kill them quickly with a bite in the back of the neck. | | |

The first abdominal segment (propodeum) usually has dense and dotting hair on its surface. The females have a sting for defense at the rear which is missing in the males. The females have strong bristles on their front feet which they use todig. The bee wolf can easily be confused with Bembix rostrata. | | |
| While the males feed on the nectar of various plants, the females in Central Europe prey solely on the workers of honey bees (Apis mellifera). To detect prey they deploy their visual skills as well as their strong sense of smell. When a flying honey bee is clearly identified, the attack is immediate. The bee wolf ...
...ses out nectar and body fluid from the prey with its powerful front legs and eats this immediately. The bee itself is not consumed and is subsequently dropped. Transport of the prey into the bee wolf’s nest is only to supply food for the larvae. The females occasionally also feed on nectar, which they obtain directly from flowers. | | |
| Adults can reach body lengths of up to 8 mm; the females are usually 5-7 mm in length, the males, 5 mm. The body of the rabbit hutch spider, especially the males, is flat. The body colour varies from shades of red to brown. A distinctive characteristic is the oily sheen, which originates from their b...
...t hutch spider, especially the males, is flat. The body colour varies from shades of red to brown. A distinctive characteristic is the oily sheen, which originates from their bodies and earns them their name with regards to the latin name. While females are generally reddish brown in colour, the males are rather darker brown. The underside of the body is pale brown. The entire body and limbs are covered in fine light hair, the thickness of which can only really be seen under a microscope. | | |
| Mating occurs in spring and the males die afterwards. Shortly thereafter, the females start building the nest on bare, dry, sandy soil sites. For this purpose they dig a main gallery, which is up to 60 cm deep and leads into the ground, and into diverse brood cells (incubators). The entrance to the nest looks like a crater surrou...
...allery, which is up to 60 cm deep and leads into the ground, and into diverse brood cells (incubators). The entrance to the nest looks like a crater surrounded by a small mound. The brood cells are filled with a pulp of pollen and nectar by the females and afterwards they lay an egg on this mixture. A few days later the larvae hatch. The development of the larvae to the point of pupation takes a few weeks. The pupae overwinter. | | |

Crepidodera aurata reach body lengths of 2.5-3.5 mm. Its elongated and oval shaped body has a metallic sheen. The entire upper surface area of the females is greenish-gold in colour; that of the males is greenish-blue, blue or purple. Longitudinal rows of dots are visible on the forewings (elytres). The brown legs to the ankle are much thicker in the upper section of the rear pair, with which the w...
...e 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 females lay their eggs on the leaves of the forage plants of their larvae. The eggs are yellowish and spindle-shaped.
The larvae hatch in summer. They are 5-6 mm long, black and resemble a small slug. The larvae live sociably on the same host plants (s... | | |
