Outcome of the different analyses testing the effect of sociality and adulticide in male and female same-sex sexual behaviour and after controlling for sampling effort (see Methods and Tables S1 & S9 for full details)

	Sociality	Adulticidea	S x A
Female same-sex sexual behaviour
Sampling effort as covariate (subset I)	0.65**	−0.37	0.24
Sampling effort as covariate (subset II)	1.08***	−0.15	−0.24
Sampling effort as weighting factor (subset I)	1.89***	1.60**	−0.23
Sampling effort as weighting factor (subset II)	2.21***	1.57*	−0.28
Sexual behaviour studied profusely (subset III)	1.03***	0.62	−0.42
Overall behaviour studied profusely (subset IV)	1.29***	0.41	−0.43
Male same-sex sexual behaviour
Sampling effort as covariate (subset I)	1.04***	0.64*	−1.32
Sampling effort as covariate (subset II)	1.04***	0.64*	−0.63
Sampling effort as weighting factor (subset I)	1.70***	2.53***	−0.92
Sampling effort as weighting factor (subset II)	1.70***	2.63***	−0.92
Sexual behaviour studied profusely (subset III)	1.17***	1.28***	−1.28***
Overall behaviour studied profusely (subset IV)	0.10	0.99**	−0.04

^aFemale adulticide was included in those models testing the evolution of female same-sex sexual behaviour and male adulticide in those models testing the evolution of male same-sex sexual behaviour.
