Spider - Zygiella - Male
Elkton, Douglas County, Oregon, USA
August 20, 2010
Found on house siding, attracted to bugs which were attracted to porch lights. The house is in the country, surrounded by many white/black oak and fir. Based on this image , my guess would be Zygiella atrica.

From Rod Crawford
I've never seen carpenteri, but the dorsal image from Douglas County OR does look a lot like Z. atrica. The ventral image could be anything but the habitat makes it likelier to be x-notata.

Let's leave there here for now.

Moved from Zygiella x-notata.

P. carpenteri
Based on range I don't think we can discount P. carpenteri at this point.

Rod Crawford says:
Positively a Zygiella, but I couldn't tell the sex or species for sure w/o a view of the palps. Male atrica have very distinctive palps, should have been able to tell even at this scale if one could but see them.

From me...I think you're fine to leave it here though. Did you get any shots from the front?

Front shot
I always try for a front shot (and bottom, if I can manage it), but in this case I was standing on the deck steps, and a frontal shot of the spider was beyond my reach. A step to the left put me at greater distance and worse angle. Next time I find one, I'll try teasing it into a better position with a stick, or something, however, when I try that, they usually jump/fall off the wall, then run and hide through the spaces between the deck boards (one time I poked what I believed to be a grass spider; it landed on my hand and ran up my sleeve; never did find the little guy - thankfully, it was kind enough not to bite).

=] spider up the sleeve
Funny. I do find that Zygiella are not very receptive to poking... in fact they are the least receptive of any type of spider I have come across. I don't suggest poking Zygiella because like you said they will immediately fall and all chances of a shot will be lost.

Moved from Spiders.

male Zygiella
Looking at the range I'd guess it's more likely x-notata. X-notata is also more often found on structures.
