It's a Golden Silk Spider. Some years I've had dozens of them in my yard. Never been bit. Here is a link that might be useful: spider pic

Yes, an orb weaver. Probably just hanging out in a sheltered place for the day. She'll go back to her web in the evening.

Here's a site with tons of Orbweavers. I'd say safe, just a bit creepy when you get zapped by their webs at night, but they're gone by morning and alot less bugs. Here is a link that might be useful: Orbweavers

It's not a spider. This is another type of arachnid known as a "Harvestman", or as these are better known in the US, a "Daddy Long Legs". Harvestmen differ from spiders in many respects. They have only one body segment, while spiders have two. They lack venom glands or fangs, so they cannot bite, and they feed almost exclusively on decaying plant material, algae and mold and mildew. They have no silk glands or spinnerettes, so they cannot produce a web, and unlike male spiders, which use specialized front legs called pedipalps for mating, male Harvestmen actually have a true penis! Contrary to the popular urban legend, these are NOT venomous at all; that got started in Australia where the Cellar Spider(Pholcus phalangiodes) is commonly referred to as a "Daddy Long-Legs", too. It IS venomous, but not the most venomous spider in the world by a long shot, and it can bite humans, contrary to that urban legend, but almost never does. Harvestman, on the other hand, cannot bite at all.
