Oecobius navus
Oecobius navus is a small cosmopolitan cribellate spider species species found across the world. Description. Both adult males and females are approximately the same size, with a body length of 2–2.5 mm (0.08 – 0.10 in). The carapace is almost circular, pale brown, with a dark patch in the centre which sometimes extends to the ocular region, and a thin black marginal line. The abdomen is coloured a yellowish brown, with black spots over smaller white flecking. Their posterior spinnerets are long, with a tubule between them. The legs are short, and coloured as the carapace; they vary from  being unmarked to having distinct, dark annulations. They have eight eyes, however the posterior median eyes are reduced to being flat, irregular silver patches. The other six eyes are grouped into two pairs of three. Distribution and habitat. "Oecobius navus" is native to Europe and Northern Africa, however it has also been introduced to South Africa, China, Korea, Japan, New Zealand, and the Americas. It builds flat webs with lateral openings with a diameter of about 3 cm under rocks, on ceilings and along the corners of walls with protruding signaling threads. Behaviour. Hunting. As with other "Oecobiids", "O. navus  have an unusual hunting method; they run around their prey, using the anal tubule and spinnerets to coat it in ribbons of sticky silk. Once their prey is fully trapped in the silk, the spider bites it. Reproduction. Prior to copulation, the male constructs a tubular mating web above the female's retreat. He then attempts to entice the female inside; if she joins him inside, they mate. As with many spider species, the female may cannibalize the male during or after copulation. The female spins several small egg sacs, each containing 3–10 eggs, and abandons them. Taxonomy. Although this 	Oecobius navus
