Orb Weaver? - Araneus marmoreus

Orb Weaver? - Araneus marmoreus
Central, Illinois, USA
May 14, 2004
Is this an orb weaver and can anyone tell me anything about this spider? I don't know very much about spiders, but this one is beautiful. Notice the orange colored eggs in the sack behind it. Great photo opportunity.

May is a strange time of year
to see this beauty. This is what they normally look like in November just before they die. Any ideas on how this one lived through the winter? Was it inside, staying warm and feeding?

Kinda looks like...
Araneus marmoreus
Maybe the color in your photo is a little off?

 
Marbled orb weaver
I agree, Troy.

 
Color
We photographed one in the fall in Cincinnati that had this same rich orange color. Here's a little blurb we found on the net:

New York State Conservationist
June 01, 2003

In the February 2003 issue of the Conservationist, we incorrectly
identified the Hunter Orange Spider as a crab spider.
According to Linda S. Rayor and Cole Gilbert of the Cornell University
Department of Entomology, the spider is actually a marbled orb-weaver
Araneus marmoreus of the family Araneidae. As the spider matures in
autumn the color of the abdomen changes to a bright orange. Rayor and
Gilbert were surprised to see a photo of the spider near snow, as most
individuals die by mid-November, leaving only the egg sac(s) to
overwinter. We regret the error.

Color
No, the color is not off. The brightness is caused by the flash. I posted another photo of the same spider, but without the flash. It is quite orange.

 
color
I can concur the color is not off, as I just uploaded a pic of the exact same animal with identical coloration. I will also add that the spider was just that orange *before* the pic was taken, so you can't blame the flash.

We used to own a pest control company down in the Tampa area, and hubby came in to have me look at his find. Neither of us had ever seen an arachnid this colorful!
