spider web


It takes about one hour for a spider to construct an
elaborate web of silk thread, called an orb web. 
The orb web is the most efficient type of spider web,
since it covers the greatest area with the least amount 
of silk. A spider usually spins a new orb web every day 
to maintain the stickiness (and insect-trapping capability) 
of the threads. Throughout the day, the spider makes
 frequent repairs to damaged threads.
