How does an orb web spider make its web?
No, none of these ideas are true. The solution is simple. The spider
releases a sticky thread that is blown away with the wind. If the breeze
carried the silken line to a spot where it sticks the first bridge is
|After the first horizontal line the spider makes a loose
thread and constructs with a second thread a Y-shaped line.
These are the first three radii of the web. Then a frame is constructed to attach the other radii to.
|After all the radii are completed the spider start to make
the circular threads.
At first non-sticky construction threads a made. The distance between the threads is so wide that the spider can span the width with her legs.
Finally the sticky thread is woven between the circular thread. While
attaching the sticky thread to the radii the construction thread is removed
by the spider.
After a night of hunting the web becomes worn out. The spider removes the
silk in the morning by eating it, only leaving the first bridge line. After
a daytime rest the spider constructs a new web in the evening. If the catch
was low and the web is not heavily damaged the web may stay during the day
and be reused after minor repairing.

The construction told here is very simplified. The site
below shows animations of the real construction.
