We report the relative abundance of inflorescence tissue feeders among three willow species ( Salix integra , S. miyabeana and S. sachalinensis ) with reference to the plant sexes. We found that (i) a total of 270 individuals belonging to six species and two orders were recorded from willow inflorescences; (ii) the abundance of Xanthia caterpillars differed across willow species and sexes; (iii) the abundance of weevil larvae differed across willow species; (iv) Gypsonoma bifasciata abundance was affected by sex and inflorescence size; and (v) Nemophora raddei was collected from a single female S. miyabeana tree. Although nitrogen content of inflorescences is not likely to affect the herbivory pattern of inflorescence tissue feeders, inflorescence size is likely to affect the abundance of Gypsonoma caterpillars.
