Map of the most likely BMSB invasion pathways connecting native and established populations across the globe, summarizing the results of our ABC analyses. Red dots on the map indicate the relevant native or established populations that are part of separate invasion pathways. The map’s pathways are directional and labeled with the source population(s) listed, along with the calculated probabilities. The abbreviation NW refers to the northwestern population within the United States (US), CA refers to the US state of California, and the small arrow within the text provides additional clarity regarding the direction of the pathway. The base map, titled Blank Map Pacific World, was created by Dmthoth (https://commons.wikimedia.org/wiki/File:Blank_Map_Pacific_World.svg) and altered to show the invasion pathways.
