Abstract: Analytical studies were conducted on the species composition of galls occurring on the leaves of Tilia cordata Mill. in the Ojców National Park in 1997-1998. The species composition of galls was identical in two years. Galls were caused by 6 species. The most numerous species were Eriophyes leiosoma (Nalepa) in 1997 and Phytoptus tetratrichus tetratrichus Nalepa in 1998.
The index of occurrence frequency and Agrell's index of species co-existence have been calculated. This index reached the highest values in both years for E. leiosoma and P. tetratrichus tetratrichus.
