 Its habit of walking with its body and legs flattened against a surface helps "Phaeacius" to be unobtrusive.While almost all jumping spiders are predators, mostly preying on insects, on other spiders, and on other arthropods, "Phaeacius" does not use the usual hunting tactics.Most jumping spiders walk throughout the day, so that they maximise their chances of a catch, and jump on their prey and then bite it.
