Web
Adult spiders build an orb-web with two sectors without connecting threads in one of the two upper corners. The signalling thread in the middle of these sectors leads to the spider's hideout. In the evening and at night, however, the spider sits in the center of the web. It renews the web in the morning hours.
A normal web consists of about 25 to 30 radial threads. Young spiders, and sometimes adults, build webs without the free sectors, especially if the angle between signalling thread and radii gets too big.

Famous quotes containing the word web:
“Being so wrong about her makes me wonder now how often I am utterly wrong about myself. And how wrong she might have been about her mother, how wrong he might have been about his father, how much of family life is a vast web of misunderstandings, a tinted and touched-up family portrait, an accurate representation of fact that leaves out only the essential truth.”
—Anna Quindlen (b. 1952)
“For us necessity is not as of old an image without us, with whom we can do warfare; it is a magic web woven through and through us, like that magnetic system of which modern science speaks, penetrating us with a network subtler than our subtlest nerves, yet bearing in it the central forces of the world.”
—Walter Pater (1839–1894)
“The delicate, invisible web you wove
The inexplicable mystery of sound.”
—T.S. (Thomas Stearns)
