Relative contribution (%) of the ecological factors contributing toward predicting the distribution of Aedes aegypti and Ae. albopictus mosquito vectors in Canada and the United States for the time period 2001–2016.

Climatic and land-use data	Ae. aegypti [mean (95% CI)]	Ae. albopictus [mean (95% CI)]

Mean maximum daily temperature	13.1 (12.4, 13.8)	—
Number of days $\ge 10°\mathrm{C}$	3.7 (3.6, 3.8)	19.6 (18.7, 20.3)
Mean daily temperature in January	10.0 (9.7, 10.2)	3.6 (3.6, 3.7)
Number of days $\ge 20°\mathrm{C}$	9.6 (9.4, 10.3)	7.9 (7.6, 8.1)
Mean total monthly precipitation	6.0 (5.8, 6.2)	8.7 (8.6, 8.8)
Mean daily temperature	8.1 (8.0, 8.4)	5.4 (5.4, 5.5)
Urban land cover	—	8.1 (8.1, 8.2)

Note: The relative mean contribution and 95% confidence intervals (95% CI) for the covariates in the Aedes spp. models are presented in the respective columns. The covariates that contributed $\ge 10\%$ to the model were considered most influential. —, indicates covariate dropout during model simplification process.
