Abstract. The aim of this study was to describe the communities of oak leaf-miners of the genus Phyllonorycter Hbn. in various types of forest habitats. The research was conducted in three study areas in central Poland. Seven of the eight Phyllonorycter species known from across Poland were found and identified using adults that emerged during rearing and/or mine characteristics. Dominance structures in four different types of forest habitats were compared. Significant preferences for poor coniferous forest habitats were stated in the case of P. roboris, while preferences of P. heegeriella were for fresh broadleaved forest habitats. The occurrence of P. lautella coincided with the presence of numerous oak seedlings, preferred as a host plant.

Key words: mining insects, insect community structure, forest habitat type, oak feeding Lepidoptera.
