Insects hold significant popularity among Japanese people, resulting in a wealth of insect specimens and extensive literature on their distribution and ecology. Consequently, there is an abundance of insect specimens and various records, which are potentially invaluable for advancing the field of entomology. In our study, we utilized records of beetle–tree associations on an oceanic archipelago to elucidate general patterns of island insect–plant interactions. Additionally, we examined an ecological aspect of a dung beetle species using historical specimens.
