Appendix A1

Table A1. Details on prey taxa hunted by wasps of the studied populations/periods, together with biological information and consequent assignment to the

‘weak mobility’ or to the ‘high mobility’ category. References for prey biology are also reported. If prey genera do not appear is because the sample was just separated in morphospecies within each prey family.
