Illustration of the measurements used for calculating the four morphometric variables (from Dirsh 1953) (a) and list of the eleven behavioural variables (b). E, the length of the fore wing; F, the length of the hind femur; C, the maximum width of the head; H, the maximum height of the pronotum; P, the length of the pronotum; V, the minimum distance between the eyes.

Box-Cox transformations for the four morphometric variables and the eleven behavioural
variables. The formulae presented in the table correspond to the transformations yielding the
best fit to the normality hypothesis among the families of transformations 
if λ ≠ 0, or, x = x ln(x) if λ = 0. Because raw behavioural data distributions included negative and null values,
we added 2 at each raw behavioural value to conform to the requirement of strictly
positive x values of the Box-Cox transformation families. Details of abbreviations for morphometrical
and behavioural variables are provided in the Additional file 2.
