The Stratiomyidae are a basal brachyceran family belonging to the Orthorrhapha and Tabanomorpha. European members of this family are diverse, ranging from 2.0 to 20.0 mm in length. Their colour is often striking, dark with a yellow, white or greenish pattern, with metallic reflections known in some species. Some species are quite slender, whilst others are stout or conspicuously flattened. Compound eyes large, contiguous in males (with some exceptions) and separated by a band-shaped frons in females. Antenna consisting of two basal segments and an annulated flagellum, the last two flagellomeres sometimes forming an apical or subapical style or arista. Three or four veins arising from discal cell on wing. The integument of the larvae is rough and strongly sclerotised, having a honeycomb or mosaic appearance. Two morphological types of larvae reflect the two main larval habitats, terrestrial and aquatic. All larvae are saprophages, living as micropantophagous scavengers. Adults, as typical nectar feeders, are found on a wide range of flowering plants, especially umbels alongside water margins but also in open sunny places.

In Europe the family includes 138 species in 27 genera (Rozkošný 2007), with an additional new species described recently (Stuke 2004). 69 species are included in the present checklist: 66 from the Czech Republic (56 from Bohemia and 62 from Moravia) and 66 from Slovakia. Since the PCV2 (Rozkošný 1997a), the number of species in the Czech Republic has increased by 3 (3 in Bohemia and 2 in Moravia) and in Slovakia by 4. A review of earlier faunistic data from the Czech Republic has been given by Rozkošný (1998) and Rozkošný and Barták (2000). The species richness of the stratiomyid fauna is relatively well-known in both the Czech Republic and Slovakia.

The monograph of the European species by Rozkošný (1982-1983) summarises all known data on adult and larval morphology, biology, distribution, systematics, and economic and hygienic importance, including keys to the species. A key to the Palaearctic genera (both larvae and adults) was compiled by  Rozkošný (1997b), the same author also published a monograph of the aquatic species of Central Europe (Rozkošný 2000). A set of interesting recent records extending knowledge of species distribution in the countries of Europe was published by Mason and Rozkošný (2003). The nomenclature and classification used here follow the world catalogue by Woodley (2001).
