Effect of temperature on the mating behaviour of male G. holbrooki when exposed to females acclimated to either 18 or 30°C for six weeks. (a) The total number of minutes males followed females during 40 min observation period, (b) the total number of coercive mating attempts, and (c) the total number of mating attempts made per minute of following females (A min−1). Data represent means ±s.e. Asterisk denotes a statistically significant difference between acclimation groups at the level of p<0.05.
