 A few web spiders run far away when they sense the un-rhythmical gait of a "Portia" entering the web – a reaction Wilcox and Jackson call ""Portia" panic".If a large insect is struggling in a web, "Portia" does not usually take the insect, but waits for up to a day until the insect stops struggling, even if the prey is thoroughly stuck.When an insect stuck in a web owned by "P. labiata", "P. schultzi" or any regional variant of "P. fimbriata", and next to a web spider's web, the web spider sometimes enters the "Portia"′s web, and the "Portia" pursues and catches the web spider.
