The slope of the regression line from these experiments with medium-sized females was used to estimate the increase in frequency for every increase in 1°C as 8–13 Hz. Group Flights Temperature remained a highly significant factor for female flight tone in the group recording experiments ( Fig. 4 ; LMM: F = 325.47; df = 1, 35; P < 0.001).
