Figure 3. Total range of individual variation of temperature regression lines for 
the five major call characteristics A-E of Ch. plorahunJa. The area above and below 
each straight line includes within it the linear regresssions for all 10 individuals tested, 
while the line itself summarizes temperature data for those 10 insects in a single 
regression equation. Axes and labels as in Fig. 2. 
A: y = 4.27x- 15.37, r-’= 0.95 
B:y = 2.69x+ 3.41, r^= 0.88 
C: y = 0.96x + 18.33, r^= 0.65 
D; y = 3.25x - 29.72, r^= 0.83 
E:y = - 39x+ 1620, r^ = 0.83
