1. Sekhukhuneland – one elevational transect from 750 m to 2100 m a.m.s.l. was sampled. This transect consisted of 10 elevation bands. Within each band, four sampling points, separated by at least 300 m, were selected. 10 traps were installed in a 1 x 10 transect, with a trap spacing of 10 m, at each sampling point. Traps were partially filled with a propylene glycol /ethanol mixture and were active for 5 days. The sampling protocols closely followed those used on other elevational transects (Bishop et al. 2014, Journal of Biogeography, 41, 2256–2268) to maximise dataset compatibility and allow effective comparisons between projects. Sani Pass – one transect was sampled to complement the sampling that has already taken place in this region (Bishop et al. 2014, Journal of Biogeography, 41, 2256–2268). Three elevations were sampled (0 m, 450 m and 3200 m a.m.s.l.). Within each band, four sampling points, separated by at least 300 m, were selected. 10 traps were installed in a 2 x 5 grid, with 10 m between traps. Traps were partially filled with a propylene glycol /ethanol mixture and were active for 5 days. Hlatikulu – Two sites at approximately 660 m a.s.m.l. were sampled. Four sampling points, separated by at least 300 m, were selected. Within each band, four sampling points, separated by at least 300 m, were selected. 10 traps were installed in a 2 x 5 grid, with 10 m between traps. Traps were partially filled with a propylene glycol /ethanol mixture and were active for 5 days.
