A Labyrinth Spider Answers my Knock

Different from other spiders in the family Agelenidae, the A. labyrinthica, has a set of at least four trichobothria on the upper side of their tarsus of the first pair of legs. A. labyrinthica have approximately 25 trichobothria per walking leg. These hairs help the spider detect prey that has been caught in its web, or even prey that is near enough to cause vibrations in its web. The trichobothria hairs essentially act as a long-distance sensory system for A. labyrinthica that helps them detect prey with great accuracy and speed.
