    [Araneidae, Araneus] what is the big belly spider

    I found it out side on my porch on 10/4/13 @ 9.30 in the morning. I look at it at least once per day (when I get home from wrk) always curled up so tight that it didn't look like it had legs. I wasn't sure what it was till tonight when I looked and its legs were out in the web. So I blew up to it and it dropped quickly to the ground on a line (web). Scared the heck outta me I thought I killed it. It landed on its back with legs all tucked it as it usually it. After a while it crawled up on the tote so I took a pic. It has the biggest spider belly/body I've ever seen. So.... what is it? Click image for larger version.

    Something in Araneus.I'm not familiar with that ventral view, am not confident with an exact species.
    You can keep a spider, but can you truly own a spider?

    This is a garden orb weaver, which are not known to have medically significant venom.
    They hide like this during the day, Usually under or in curled leaves. They come out at dusk and make those fancy orb webs to catch moths and mosquitoes.
    This looks a little young, and from the humps on the abdomen, may be a cat faced spider.(Araneus gemmoides)

    The ventral isn't right for A. gemmoides.The spider pictured in the picture you provided is Araneus diadematus,also not this species.I have one of these in my yard, am eager to find out what this turns out to be.

    I can't see the ventral patterns well enough to make a conclusion.
    Also the spider I posted was confirmed Araneus gemmoides.

    Oh.A. diadematus and A. gemmoides have similar ventral patterns,my mistake.
