Anti-predator defenses of Pholcus phalangioides (Araneae, Pholcidae), a web-building and web-invading spider. The biology of Pholcus phalangioides (Araneae, Pholcidae) predatory versatility, araneophagy and aggressive mimicry. Predator-prey interactions between jumping spiders (Araneae, Salticidae) and Pholcus phalangioides (Araneae, Pholcidae).

But the cellar spiders have one last trick up their sleeves: when they feel the vibrations of an approaching predator, they begin to rapidly bounce and whirl around in their web to confuse and deter the approaching predator ( 5). Jumping spiders in the genus Portia are able to mimic the cellar spider’s movements in order to lure them in and give them a taste of their own medicine ( 3). Sometimes, the cellar spider even sets up shop in the newly vacant web and captures ensnared insects ( 2). Long-bodied cellar spiders commonly invade the webs of other spiders, mimic prey vibrations, and eat the spider when it comes near ( 4).
