Biology

The web of this spider is more like a sock than a purse. The web forms a tube, part of which lines a burrow; the remainder lies along the surface of the ground, disguised with soil particles (3). When insects land on this tube, the spider grabs them with its fangs and drags them inside where they are eaten. The remains of the meal are later thrown out of the tube and the hole is repaired (2). The spider spends most of its life inside this tube; only young spiderlings and males in search of females actively wander (3). Mating occurs in autumn. When a male finds a burrow occupied by a female he will tap on the silk tube. If the female is receptive, she allows the male to enter the burrow where they mate. They live together in the female's burrow for a time until the male dies. The female eats the male, and the nutrients contained within his body contribute to the developing eggs. The female produces an egg sac which she suspends within the tube. The eggs hatch the next summer but the young spiders will not disperse until the spring of the following year. It takes around 4 years for individuals to reach sexual maturity. Males die following mating, but the females live for several years more (3).
