SYNOPSIS. Uloborus diversus adjusts its behavior while laying sticky spiral in response to stimuli it receives as it moves. The course of the last loop of sticky spiral determines the path the spider takes. The spiders probably sense the angles the sticky spiral makes with the radius and with the last loop of spiral, and use them in making decisions to turn back.Computer-simulation has shown that a simple turnback program using just these angles can produce a spider-like pattern of sticky spiral.
