New records of Diptera from nests of Micromys minutus and Muscardinus avellanarius in Slovakia

Associations of insects that live in nests and burrows of small mammals are relatively poorly explored. This work therefore tries to expand the knowledge about Diptera communities (Psychodidae and Sphaeroceridae) of two small mammals, namely Micromys minutus (Pallas, 1771) and Muscardinus avellanarius (Linnaeus, 1758). In nests of Eurasian harvest mouse two psychodid species and one sphaerocerid species, while in hazel dormouse nest one psychodid species and three sphaerocerid species have been found, all representing new nest records.
