Explanation note: Table S1. Climate, land cover and anthropogenic variables with potential to affect the behaviour and establishment of Vespa velutina. Tables S2. Correlation matrix of the climatic, land cover and anthropogenic drivers that have the potential to affect the behaviour and establishment of Vespa velutina in Europe: a) bound records; b) outposts; c) outposts >18 km. Table S3. Relation between dispersion distance (to south and east) vs time either for self mediated or jump dispersal by testing through t-test the significance of the slope of the regression when compared to zero (H0: the slope of the regression line is 0). Table S4. Effects of climatic, land cover and anthropogenic variables on the dispersal of V. velutina. Table S5. Effects of the different land cover and anthropogenic predictors on the dispersion of V. velutina, considering the predictor distance to the entire road network, instead of distance to motorways in bound records and both sets of outposts. Table S6. Set of best models with climatic and land variables according to the different datasets (1. bound records; 2. all outpost and 3. outpost 18 km). Table 7. Set of best models with climatic variables according to the different datasets (1. bound records; 2. all outpost and 3. outpost 18 km). Table S8. Set of best models with land variables according to the different datasets (1. bound records; 2. all outpost and 3. outpost 18 km). Figure S1. Variation of the mean distance of the new records within a given year to the nearest potential source: continuous area or outpost. Error bars depict standard errors. Figure S2. Relation between the dispersion of Vespa velutina and significant climatic and land cover variables according to the different datasets: bound records, all outposts and outpost 18 km (see Table
