Fig. 4

Correlations between fly cold tolerance and morphological traits (body colour or body size). Correlation between A D. flavomontana CTmin and body colour, B D. flavomontana CCRT and body colour, C D. flavomontana CCRT and body size (measured as weight), D D. montana CTmin and body colour, E D. montana CCRT and body colour, F D. montana CCRT and body size (measured as weight). Error bars represent bootstrapped 95% confidence intervals. Significant regression lines are shown with standard errors (best-fit models are presented in Fig. 3 and Additional file 1: Table S6)
