Often found on sparse, open patches of ground between vegetation. Flies rapidly when disturbed and usually resettles on a low shrub. They are highly cryptic when resting amongst fynbos, karoo vegetation or on lichen covered rocks. Unlike most antlions Pamexis karoo is not attracted to lights.

Nothing is known about the larvae of this species.
