Tetragnathidae
5 genera in Central Europe:
Tetragnatha,
Pachygnatha, Meta, Metellina, Zygiella
Spiders of this family build
orb-webs with an open hub. Only Pachygnatha adults live as vagrant
spiders. The webs of Zygiella have a closed hub and a free sector
by which a signal thread connects the web with the retreat of the spider.
