Mate choice experiment using only lab-reared crickets.

Generalised linear-mixed model analyses looking at the propensity of males to start singing, and the propensity of females to mount and mate within 10 minutes to con- and heterospecific partners. The experimental set-up between the mate choice tests differed slightly. In this experiment each individual was tested against both a hetero- and conspecific partner and we controlled for presentation order (see main text for details). The G. campestris used in this experiment were the F1-generation from wild-caught individuals and reared in the lab in 2009. The G. bimaculatus were raised in the lab for several generations. Explanatory variables retained in the final model are in bold.
