The aims of the present paper are to establish the specific structure of communities of prostigmatic and mesostigmatic mites in nests of the semi-collared flycatcher (Ficedula semitorquata) and to compare the fauna with the mites in nests of two other European flycatchers. For analysis of community structure of mites were used the indices: prevalence, relative density, mean intensity and dominance. Mite communities are strongly dominated by the species Dermanyssus gallinae and Ornithonyssus sylviarum, which were found with the highest frequency and dominance. The mite communities are characterized by a large number of subrecedent species.
