The spatial distribution and abundance of galls of Phytolyma lata were investigated. There was significant correlation between gall counts and the proportion of young leaves. It is suggested that the preference for young leaves not only ensures that good quality food is available but also that the insect is able to complete development before leaf fall. The distribution was also found to be influenced by the surface of leaf, region of leaf and size of veins.
