Volume 8 of "Research on Chrysomelidae" (RoC8) presents again examples of the attractiveness and the diversity of Chrysomelidae (sensu lato) as subjects of scientific research. The seven papers included here cover taxonomy, ecology, faunistics as well as phylogenetics. Four of these papers (Geiser, Gikonyo et al., Salvi et al., Wendorff and Schmitt) are extended versions of talks presented to the Third European Symposium on the Chrysomelidae, held on 5 July, 2018, in Naples, Italy within the frame of the 11th European Congress of Entomology.
