Abstract The escalating global movement of alien species, facilitated by increased trade and travel, poses a pressing need to comprehend their invasive potential the consequent ecological economic ramifications. Despite growing body evidence on rapid evolutionary shifts in comprehensive insights into genetic variability underlying these adaptations are constrained limited genomic resources. Understanding role variation success or failure biological invaders is thus crucial. This study focuses chrysanthemum lace bug, Corythucha marmorata , as model system investigate interplay invasion dynamics. Our analysis reveals moderate structure among countries, with significant differentiation observed within populations. Mitochondrial COI DNA haplotype network revealed shared haplotypes between Japan North America, indicating recent events introduction, while exclusive Japanese FST GST values suggest local divergence. Phylogenetic STRUCTURE analyses show clusters unique Japan, populations like SAG CER displaying higher Bottlenecks followed divergence, indicated DIYABC-RF analysis, point complex history involving multiple introductions subsequent divergence Japan.
