Cross Orbweaver - Araneus diadematus - Female
Seaside, Clatsop County, Oregon, USA
November 3, 2009
Size: 'Bout size of a quarter
Sunny afternoon saw this spider walking on top of a driveway curb at a friends house. Put a rock in its path and it stopped long enough get a good photo. Think this might be the Shamrock Orbweaver but not sure. Any thoughts?

Moved from ID Request. Lack of more prominent 'shoulders' I think eliminates gemma. Darn.

My personal opinion...
...would be that it's really just one of the Araneus diadematus with a 'less-than-common' color pattern. I think the trifolium has more guanine spots (white spots).

 
Hi Mandy, This couldn't be
Hi Mandy,

This couldn't be Araneus gemma? Na, maybe you're right. I can't tell.

Maybe you're right, Kevin
Could be gemma. I hadn't thought of that. I always assume the gemma has more pronounced 'humps/ears' on the abdomen. But in reality, I really don't know much at all about gemma anyways. It would be the right range to be finding one in Oregon, though.
