This family comprises small to medium-sized flies, with long legs and comparatively broad wings characterised by a net-like pattern of folds. Mouthparts are usually well-developed in females and reduced in males. Two genera are represented in the Czech Republic and Slovakia, Blepharicera Macquart, 1843 and Liponeura Loew, 1844. In the former, the eyes are divided transversely into two regions, the upper one with larger ommatidia than the lower one. The larvae are aquatic, living in rapidly flowing streams, often in waterfalls, and feeding on periphyton (algae, bacteria and other organic matter). Adults occur in the immediate vicinity. Females are predatory, but males possibly feed on flower nectar.

Altogether 40 species and subspecies are known to occur in Europe (Zwick 2007a, after adjustments), of which seven taxa are listed in the present checklist, including two subspecies of Liponeura cinerascens: six from the Czech Republic (five in Bohemia, six in Moravia) and six from Slovakia. There have been no additions or corrections since the PCV2. No additional species are expected from either the Czech Republic or Slovakia.

Larvae, pupae and males of the Czech and Slovak species may be identified using the keys by Tuša (1986, 1992a, b). The nomenclature is adopted from Zwick (2007a), but Blepharicera fasciata is not ranked as a subspecies.
