 Other jumping spiders show no awareness of a flattened "Phaeacius" on a matching background, and apparently survive by luck.When the background does not matches "Phaeacius"′ coloration, other jumping spiders recognise "Phaeacius" as a threat.Sometimes, especially if without prey for a week or more, "Phaeacius" may approach insects faster, from away, and if necessary turning round to face the prey.
