 In "P. labiata" and in some other species, contests between males usually last only 5 to 10 seconds, and only their legs make contact.When hunting, mature females of "P. labiata", "P. africana", "P. fimbriata" and "P. schultzi" emit olfactory signals that reduce the risk that any other females, males or juveniles of the same species may contend for the same prey.The effect inhibits aggressive mimicry against a prey spider even if the prey spider is visible, and also if the prey is inhabiting any part of a web.
