Zusammenfassung

In a laboratory study, 12 different experimental set-ups were used to examine the ability ofPortia fimbriataa web-invading araneophagic jumping spider from Queensland, Australia, to choose between two detour paths, only one of which led to a lure (a dead, dried spider). Regardless of set-up, the spider could see the lure when on the starting platform of the apparatus, but not after leaving the starting platform. The spider consistently chose the ‘correct route’ (the route that led to the lure) more often than the ‘wrong route’ (the route that did not lead to the lure). In these tests, the spider was able to make detours that required walking about 180° away from the lure and walking past where the incorrect route began. There was also a pronounced relationship between time of day when tests were carried out and the spider's tendency to choose a route. Furthermore, those spiders that chose the wrong route abandoned the detour more frequently than those that chose the correct route, despite both groups being unable to see the lure when the decision was made to abandon the detour.
