| While the adults of some dung fly species prey on small insects or larvae, other types live off feces. The larvae eat parts of plants (leaves, cambium, boll) and rotting plants , or live off feces like the adults. | | |
| | ...hycera occur in large masses they can be very annoying and can, in certain cases, lead to significant damage to agriculture, especially in the meat and milk production industry. Due to the fact that some species of Brachycera t very often reside in feces and carcasses, they can transfer diseases. Some general examples of Brachycera are : Blow-flies, house flies and Muscidae.
The Drosophilidae, or fruit flies, of which about 3,000 species are known worldwide, can cause significant damage to orcha... | | |

Others feed on dead organic material and on the fungi which live within. There are species which live from feces and others which tunnel into plants, eating from their substance.
The larvae live in soil, some also in water. The larval phase ( in total 3 stages) lasts for about 8 days. In Europe the adult flies take 2 to 3 weeks to hatch. The high reprodu... | | |
| | The females lay their eggs singly, in clusters or in rows on their forage crops. Some species hide their eggs in holes in leaves, stems or twigs. Others cover their eggs with feces. The Donaciinae live both on water as well as on water plants. Here is the egg laying in a kind of jelly. The eggs are laid in rows on leaves. The larvae bore their heads in roots, stems or leaves and suck out the plant juices. | | |

In the chambers, balls of dung are placed before the larvae as a future food supply. The side passages to the chambers are then filled with feces and sealed with clay. The larvae need approximately 1 year to grow up and then to turn into pupae.
The number of Geotrupes stercorarius is declining. | | |

Blow-flies usually lay their eggs (up to several hundred at one time) in strongly smelling organic substances such as feces or carrion. The excretions of the larvae can be problematic for humans. therefore meat which has been in contact with them should not be eaten. Due to the fact that they carry germs, blow flies are known to spread diseases.

The female flies lay their eggs on dung-heaps or compost heaps. From the first or second day after hatching, the larvae begin feeding on feces or rotting parts of plants. At the end of their third larval stage the fully developed larvae turn into pupae. This happens in the dung or compost or in the soil below it. From egg to adult fly can take 14 to 32 days.

The adults are active from February to October, and can very often be found on the plants Stellaria holostea and Tanacetum vulgare, whose nectar they live off. They can also be found on feces, which they land on not only to lay eggs, but also to eat (proteins, minerals). | | |
| | The bluebottle blow fly is active during the day from late April to September. While the males frequently sunbathe on walls or tree trunks, the females are avid flower visitors. The females can also be seen in feces and carrion. Their frequent presence in cadavers is of importance in forensic medicine. | | |
| | ...ya strenua are active from May to September in wet meadows, forest edges and gardens where they are found on flowers and on cattle or horse manure. The fertilized females lay their eggs on dung. The larvae hatch immediately and develop in the feces, feeding on the substrates. | | |
