We have a couple feather-legged spiders living by one our flower pots; I would have killed them already, but my nephews are anxious to see their egg-sacs hatch. The feather-legged spider (Uloborus plumipes) is also called the Garden center spider and the feather-legged lace weaver. It is found in most parts of the world.The feather-legged spider has extra-long, front legs; and it is known to hold the first pair of legs directly out front of itself and pressed together. The feather-legged spider spends all its time sitting in the middle of its web with its hind legs pulled up and its long, strong front legs together. The middle of the web is usually strengthened with additional silk. This spider is known to be active during the night and during the day, and it feeds on flies and other small insects. It is also beneficial to gardeners as it helps to control whiteflies (plant lice).
The female spider lays several egg sacs which she covers with silk and guards until the eggs hatch. The egg sacs are flattish, papery, and brown. The feather-legged spider lives outdoors as well as inside the house; it lacks venom glands, and is therefore harmless to humans.
