I confused this spider at first with a wolf spider, considering its stripes and
hunting stance. After looking more closely at its eye configuration, I
figured it was something else. Wolf spiders often have 2 large eyes facing
forward, and this spider did not have that configuration. Took a look in
my Australian spider books, and saw it resembled a Large Sac spider. This
has been confirmed with Mr. Hirst in Adelaide.
The featured photo is of a very large sac spider, about half the size of an
adult hand, or 3 inches long. An extensive web was built, and you can see that
partially on the last row, middle pic.
The spider on the green fabric was found in leaf litter, on the ground.
