The 16 insect species collected for this study indicating the linear measurement used to estimate size.

All collections were made within a 10 km radius of the town of Stellenbosch (S33°55.92′ E18°51.80′), except for the termite species which was collected at Wolseley (S33°24.84′ E19°12.03′). Maximum body length excluding antennae, maximum elytron length, and head width or length were used as linear estimates of size in keeping with previous studies.
