Fig. 7. Number of straight-line flights, n_l, of length l in the representations of the honeybee flights (histogram) on linear–linear scales (A) and on log–log scales (B). A Lévy stable distribution (Cauchy distribution), P(l)=(1/)/(l²+²), with scale parameter, , chosen to minimize the sum of the squared differences between the Lévy stable distribution and the data, n_l (solid line). The inverse-square law scaling of the high tail (l>10 m) of the distribution, obtained from a linear least-squares fit of the distribution (r²=0.94), is indicated (broken line).
