Feather-legged Spider

These are non venomous. About 5mm. They make a horizontal web in which they sit motionless. But once the web is disturbed they have a habit of vibrating in a circular motion. Their web do not have sticky glue like other orb weavers. The fine fibers produced are combined by comb-like bristles on the hind legs into slender silk threads with a fuzzy texture that are able to trap prey without the use of glue. The web often looks bedraggled with broken strands and the whole effect is of an ancient, abandoned cobweb with a scrap of dead plant material adhering to it. The eggs are concealed in silk egg sacs which are also suspended from the web. The female spider closely resembles these as she dangles nearby. (Wiki)
