The originally tropical and subtropical species Clogmia albipunctata (Diptera: Psychodidae) has been newly recorded in Central Europe - 9 sites in Brno, one in Prague and several sites in Slovakia. This immigrant species has colonized mainly anthropogenic habitats with suitable temperature conditions for its overwintering. During the warm periods of the year, it also temporally occurs in natural habitats (tree holes). It is still unclear whether the "new" species poses a real threat to the biodiversity of our native fauna. The results of laboratory breeding and field observations, which extend our knowledge of the bionomics of C. albipunctata, are presented, while relevant health risks (myiasis) and sanitary control are discussed.
