 Populations from Los Baños and from Sagada , both in the Philippines , have slightly different hunting tactics . In laboratory tests , Los Baños P. labiatas rely more on trial and error than Sagada P. labiatas in finding ways to vibrate the prey 's web and thus lure or distract the prey . Around Los Baños the web @-@ building Scytodes pallida , which preys on jumping spiders , is very abundant , and spits a sticky gum on prey and potential threats . A P. labiata from Los Baños instinctively detours round the back of S. pallida while with plucking the web in a way that makes the prey believe the threat is in front of it . In areas where S. pallida is absent , the local members of P. labiata do not use this combination of deception and detouring for a stab in the back . In a test to explore P. labiata ′ s ability to solve a novel problem , a miniature lagoon was set up , and the spiders had to find the best way to cross it . Specimens from Sagada , in the mountains , almost always repeated the first option they tried , even when that was unsuccessful . When specimens from Los Baños , beside a lake , were unsuccessful the first time , about three quarters switched to another option .
