How do they do that?


The accompanying picture shows a spider's web. You may not be able to see the web itself which is in the top left corner but you should be able to make out the top thread under from which the web is suspended. The thing that amazes me is how the top thread was put in place. It is over four feet long and is attached at the left end to the tip of the hawthorn about eight feet above the ground (top left of photo) and at the other end to the lime about six feet up (on the right margin). Did the spider jump four feet horizontally streaming the thread behind it? That is the only sensible explanation. That is some feat.
