Adults are medium-sized to large flies (body length 5.0-15.0 mm). Postvertical setae parallel to diverging, vibrissae absent, and dorsal preapical setae on tibiae present. Wing venation complete, i.e. costa unbroken and subcosta not reduced. The immature stages are known only for two species. The larvae live in decaying carion, excrement and rotting fungi. The adults are frequently found in forests in shaded humid places with low vegetation, searching for flowing sap and suitable pabula for the development of their larvae.

Only four species in two genera are known in Europe (Carles-Torlá 2007), and three of them are common in Central Europe. These were also recorded from the Czech Republic and from Slovakia in the PCV2 (Martinek 1997). The number of species is very probably final because the fourth European species is known only from Finland and Sweden.

The basic characteristics of the family in the Palaearctic region have been given by Ozerov (1998), and all the Central European species can be reliably distinguished using the keys by Czerny (1930) and Falk (2005). Earlier faunistic data are summarised by Martinek and Barták (2001).
