FPG. 102. The triangle spider, Hyptiotes sp. (California), with its web; the 

 spider rests on the taut guy-line, with a loop of the line held between

 loosens the hold of its hind feet on the guy-line, thus allowing the web 

 to spring forward sharply and further entangle the prey. (From 

 Jenkins and Kellogg.)
