Contrasting responses of Harmonia axyridis and Cheilomenes lunata maintained at three temperature treatments. a critical thermal maxima (CTmax) of female and male H. axyridis (top row) and C. lunata (bottom row) as a function of body mass. Slopes are based on the best model parameter estimates b total number of eggs laid by H. axyridis (left) and C. lunata (right) at each temperature treatment c adult mass (mg) of H. axyridis (left) and C. lunata (right) in each treatment. In b and c different letters indicate significant differences between groups. Values are based on the best model parameter estimates and standard errors.
