Phoridae were studied In pine canopies in three pine forests in Poland: Puszcza Białowieska, Puszcza Biała and Bory Tucholskie. 116 species of scuttle fly were recorded, including 2 new to science and 12 new to Poland. The phorid communities of this habitat are dominated by species of the genus Megaselia, that are common and have a wide distribution. The structure of phorid communities depends on the degree of habitat degradation of forests. Increase of the habitat degradation results in a decrease of number and abundance of species, especially zoophages.
