Found this in its web on the wall inside home. Zosis geniculatus is common and easy to recognise. As it is venomless it is a harmless method of controlling insects in your house. The abdomen in triangular in side view, humped in front with a pair of tubercles on the summit.The spider spins a horizontal or inclined orb-web. It creates a ragged blue grey circular web, with star shaped egg sacs. Insects trapped in the web are rolled with the hind legs and wrapped in silk. The bundle is eventually carried to the hub of the web and sucked dry.
Under bridges or in old garages and abandoned sheds. Found throughout the tropics.
Uloborids and several related families have a cigar-shaped plate (cribellum) on the underside of the abdomen, in front of the spinnerets. The upper margin of the second last segment (metatarsus) of the fourth leg is armed with a row of strongly curved spines known collectively as the "calamistrum" (arrowed in diagram, right). It is through the combined action of the cribellum and calamistrum that the bluish silk characteristic of the Uloborids is produced. The front legs of the Uloborids are extraodinarily long, often longer than the entire length of the body. Unlike other spiders, Uloborids do not possess venom glands.
