Hyptiotes creates a triangular web and sits at a vertex until it detects vibrations that signify the collision of its prey. At this moment the spider releases a coil of silk which it has held taut in such a manner that the tension of the web causes it to entangle the prey. The spider then wraps its prey in special wrapping silk.[1]
