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 they feed on nectar or... | | |
| | Dor Beetles - Earth-boring dung beetles | | ...etle lives in forests, steppes and fields.
The adult beetles are active during the day and night. They are clumsy in flight. Adults and larvae feed on faeces, rotten plants and fungi. Some eat leaves, others do not apply to food.
Dung beetles dig complex underground systems of passages (often beside dung). The young are fed and taken care of in individual chambers. | | |
| | | Geotrupes stercorarius | | ...r wing covers each have 7 long rows of weak spots. The beetle can make noises. with its rear hips.
The beetle prefers to live in forests. The adults fly at night close to the ground making a loud humming sound. In the spring males and females dig a 40 cm long underground tunnel for mating, which leads into several chambers, which can be reached through temporary tunnels. In the chambers, balls of dung are placed before the larvae as a future food supply. The side passages to the chambers ar... | | |

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. | | |
| | While the males in autumn die after mating, the females overwinter hidden. In spring they dig a nest, which consists of the main course (leading diagonally into the earth) and several short side galleries leading to the cells for the brood. They lay one egg only in each brood cell. The egg is located on a nectar pollen mixture, which (as foo... | | |
| | ...Amegilla are active from March to June. They are often visible on deadnettle (Lamium) or on other species of the mint family (Lamiaceae), as well as on borage (Borago officinalis) and species of the primrose family (Primulaceae).
The females dig tunnels in loose soil for their nests. These tunnels are approximately 100 mm long and sometimes branched. It can happen that several females build their nests very close to each other. The nests are equipped with small chambersshaped like hazeln... | | |
| | 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 surrounded by a small mound. The brood cells are filled with a pulp of pollen and nect... | | |
| | Mature larvae are able to secrete a substance which drives away their competitors ,especially adult beetles of the same species, from the leaves of the forage plants. At the end of the third larval stage, the larvae dig down into the soil to a depth of about 2cm and pupate. After 6-9 days the adult beetles hatch from their pupae. They have a flight radius of about 10 metres. In late autumn they begin eating intensively and continue this over a period of a few d... | | |

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 of the dead tissue with which they feed the larvae after hatching. Beetles of the genera Thanatophilus, Necrodes and Silpha also live on carrion, but without burying it. | | |

In autumn, when the damaged acorns fall from the tree, the larvae, which have now reached their full size, bore their way out and dig into the ground, where they settle themselves in small chambers about 250 mm beneath the surface of the ground for the purpose of overwintering. In the following spring, the larvae pupate in their chambers. They leave the pupae in May or June as adu... | | |
