This special volume, Research on Chrysomelidae (RoC10) edited by Caroline S. Chaboo, Yoko Matsumura and Michael Schmitt, presents recent research that range from taxonomy and phylogeny to behavior and species interactions. Some of these articles emerged from oral and poster presentations at the 11^th International Symposium of Chrysomelidae during the 27^th International Congress of Entomology, Kyoto, Japan, 2024. This volume is another contribution in the RoC series began by Pierre Jolivet to promote communication and collaboration among leaf beetle researchers and make their results accessible to the general scientific public.
