It has a closely woven mat in the center and two zigzag bands 

 of white silk extending up and down. 



The webs of Tetragnatha, Meta, and Acrosoma have a hole 

 in the middle, the irregular center being entirely removed.

 new rays have been made and a quarter of the old web remains at the right. 



Insularis and trifolium live always in tent-shaped nests, with a 

 thread, or several threads, leading to the center of the web. 

 Globosa, labyrintkea, and Zilla have a similar thread from 

 nest to web, and leave open a segment of the web through 

 which it passes.
