Abstract
The terms "reversed-route detours" and "forward-route detours" are introduced to distinguish between detours that require moving away from a goal and those that do not. We provide the first evidence under controlled laboratory conditions that salticids can perform reversed-route detours. Two species were tested: 1) Portia fimbriata, a web-invading salticid from Queensland, Australia, that normally preys on web-building spiders; 2) Trite planiceps, an insectivorous cursorial salticid from New Zealand. Although both of these species completed reversed-route detours, Trite planiceps was much more dependent on prey movement than Portia fimbriata. Interspecific differences appear to be related to the different predatory styles of these two salticids.
