Some examples are: Ammophila sabulosa, Bembix rostrata and the European beewolf (Philanthus triangulum). The sphecoid wasps are solitary. Their body length ranges from 2 mm to several centimetres. Their colouration and markings vary. In some species the base colour of the abdomen is reddish. Many species have a slender abdomen. | | |
| | The bee wolf is a solitary wasp and prefers warm, dry, sunny habitats. It is found in flat grassland, heaths, dry meadows and open sandy places. It can be encountered on the edges of sandy pits, on sunken roads, and also occasionally near areas populated by humans. Adult bee ... | | |
| | | The bodies of Vespidae are black and yellow in colour with different markings. Their wings are folded lengthwise in resting position. They have kidney-shaped compound eyes. Vespidae includes both colony forming and solitary wasps (potter wasps). | | |

Scentless plant bugs prefer to live in fields, meadows and on trees. They are solitary insects but sometimes live sociably. | | |
| | The adult wasps are mainly found on umbelliferae flowers, mint, thistle or golden rod plants. The larvae mostly live as parasites in the nests of some kinds of bees or wasps, e.g. digger wasps or solitary wasps. The fertilized females lay their eggs in spring in the nests of their larvae’s hosts. This happens near the brood’s site, which is equipped with food stores. The young Gasteruption larvae hatch after a few days and start eating the host’s... | | |

Usually one egg is placed in each nest. Egg-laying often takes place in the nests of solitary bees of the genera Hylaeus and Osmia. A few days later the larvae hatch from their eggs. Firstly they eat the eggs or larvae of the host animals and later on any food supplies found there. | | |

Around 250 eggs are laid separately. 2 - 3 weeks later the solitary caterpillars hatch. During the day they stay on the underside of the leaves. The larval stage lasts 6 weeks and then the caterpillars pupate. The pupae are striking; the middle is constrictedly built and has a hump with shiny, metallic patches on th... | | |

The caterpillars hatch after about 2 weeks and are yellowish-green and spotted black. They eat in groups. The older larvae are solitary. The caterpillars can be encountered from June to October and reach lengths of up to 40 mm. They develop a clear warning sign, and are equipped with a chemical defense system which is based on sulphur compounds and derived from the forage plants (va... | | |

In April of the next year, the hairy caterpillars hatch from the eggs and start to feed on their host plant. They are sociable at first and later solitary. | | |
