I caught this big Orb Web Spider under a tree one day. He was alive, but being quickly overrun by ants. So I flicked the ants off, and snapped a few pictures of him. He wan't very eager to move (all the better for me!), maybe the ant's had bitten him too much.
The Garden Orb Web Spiders are also called Araneus Spiders, Garden Orb-weaver, Wheelweaving Spiders or Orbweaving Spiders. The Latin or Scientific name is Eriophora transmarina.
