Orb Weaver - Araneus cavaticus - female

Orb Weaver - Araneus cavaticus - Female
Weare, New Hampshire, USA
August 18, 2005
Size: 2 in
This A.diadematus built her web right by our porch light at our cabin. Her web was huge and she probably pulled in a good couple pounds of flying insects each night :)

Im assuming its a female just because of size and shape, but please feel free to correct me. I thought this pic was unique because you can see just how hairy these spiders really are.

A. diadematus?
Nice photos. It is definitely a female orb-weaver, but I am questioning if it is an A. diadematus?

There should be distinct white spots running down the top of the abdomen, and some across (transverse) the abdomen, forming the "cross" shape on the anterior portions of the abdomen. In looking at your photos, I cannot see any evidence of the spots (not to say that they aren't there, they are just not evident in the photos). In comparing the other photos for the A. diadematus, the spots always seem to be apparent.

What do you think? :)

Not A. diadematus.
I agree with Christopher Hunt, this is NOT A. diadematus. Araneus is an almost impossible genus, in that species determination is heavily reliant on female genitalia. I encourage people to be satisfied with simply a genus determination in most cases.

Thanks
I appreciate your help Eric and Chris. Sorry I was hasty in ID'ing this to species, Im having trouble moving images right now, so if someone gets a chance to move this to genus before I do, feel free
