Mayflies (order Ephemeroptera) are an ancient group of insects whose origins go back to Carboniferous. Their life cycle consists of aquatic eggs and larvae and terrestrial „pre-adult“subimagoand sexually matured adults. The winged terrestrial stages are short-lived (they live for several hours to days). They represent a small but diversified groupof insects that occur on all continents of the world (except Antarctica and some remote islands). From Slovakia, the occurrence of 122 species from 40 genera and 16 families is reported (more than 60% of species belong to familiesBaetidae and Heptagenidae, up to 6 families are represented by only one species). From a qualitative and quantitative point of view, their larvae form an important part of the macrozoobenthos of flowing and, to a lesser extent, stagnant waters.
