Portia fimbriata , a web‐invading, araneophagic salticid that uses aggressive mimicry to deceive its prey (web‐building spiders), takes indirect routes to reach its prey (i.e. it makes detours). Data are presented from 18 instances of Portia making detours to reach prey in nature, the prey being five different species of web‐building spiders. Portia spent 17 min (median) per predatory sequence with the prey out of view and covered 375 mm detouringper sequence. These detours were longer and more complex than those previously recorded for salticids, and these are the first detailed records of detouring behaviour by a salticid in the field.
