The flies we call Dung Flies actually belong to more than just one family. The Sepsidae are dung flies as well and are better known as Lesser Dung Flies. They too deposit their eggs in dung and even the adults eat rotting organic materials. Most members of this family are small, shining black flies with a very rounded head and a body shaped like an ant's. This way they do remind one of Mickey Mouse. It is very difficult to tell the various species apart. The way the species below hold its wings is typical of this family: half open and half upright. Below probably the most common representative of these flies in the Benelux: Sepsis fulgens. See more: http://www.gardensafari.net/english/r...
This fly is often seen visiting flowers in order to obtain a carbohydrate meal. But it is most often associated with a variety of animal dung, particularly that of cow and horse, on which the female will lay her eggs, and the larva will feed. Male S. fulgens are often more common on dung, as it here that they will wait for the females. In fact, males are so keen, that they will very often mount any visiting fly that bears a slight resemblance to another Sepsis, including other males, but they will quickly dismount again when the error is apparent. When a suitable mate is found the male will stay firmly attached to the female, and copulation will normally take place later and at another location. So attached are the pair that it usually takes a 180-degree maneuver for the couple to part company. S. fulgens are also known for their swarming behaviour, and these swarms have been estimated to sometimes reach 30,000 to 50,000. See more: https://en.wikipedia.org/wiki/Sepsis_...
The Lesser dung fly (Sepsis fulgens) belongs to the genus Sepsis, in the order Diptera, suborder Brachycera, infraorder Muscomorpha (Section: Schizophora; Subsection: Acalyptratae), superfamily Sciomyzoidea, family black scavenger flies (Sepsidae), subfamily Sepsinae and tribe Sepsini. Scientific synonyms for Sepsis fulgens are: Sepsis cynipsea, Sepsis communis, Sepsis concinna, Sepsis tonsa, Sepsis and Sepsis vibrans minimus. The body of adult Sepsis fulgens is usually dark, with a metallic sheen and 2-4 mm in length. The abdomen is roundish with a "wasp waist" at the front and altogether the bodyresembles that of an ant. The wings are completely transparent with a dark spot at the top. Males can be distinguished by the shape of their front legs. Adult flies give off a peculiar smell.
Sepsis fulgens are diurnal and active in Southern Europe from February-November and in Northern Europe from May to September/October. They prefer habitats such as forest edges, riverbanks, streams, lakes, meadows and wetlands, where they can often be found on foliage and flowers in the sun. They live on sweet nectar and other fluids rich in carbohydrates from plants such as common hogweed (Heracleum sphondylium), coltsfoot (Tussilago farfara) and goat willow (Salix caprea). They also feed on dung heaps and carcasses to obtain protein and minerals. 30 000 to 50 000 flies can be encountered at the same time, especially in autumn when they gather to overwinter and to mark their mating spots with special scents in the vicinity of their winter habitats for next year. In extreme cases, several hundred thousand can gather. In spring, after overwintering, the flies meet up at the marked places. Male Sepsis fulgens usually then visit dung-heaps where they await females for mating. The mating takes place at another location later on. 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.
