Orb Weaver - Zygiella atrica - Zygiella atrica - female

Orb Weaver - Zygiella atrica - Zygiella atrica - Female
Marblehead, Essex County, Massachusetts, USA
August 14, 2004
Web to 20 cm female measures 8mm. Found in hub only at night appears to favor salty air. This is either Z. x-notata or Z. atrica. I personally think it's the latter. You can search by either name or go to "Nick's Spiders".
I'm eliciting opinions as to species. A number of images; male/female, have already been posted in the orb weaver section.

Moved
Moved from Zygiella. Based on known range and since I've seen both species I agree this is most likely Z. atrica.

Just catching up on emails
And got your notes about these. I changed the guide you mentioned from Araneus to Zygiella. Should we just put this one there as well? We could leave it here if you want to get more eyes on it.

Troy, I would like
Eric's input at the very least. So until then, I think it should stay. I'm about 75% confident it is Z. atrica - the two species are similar.

Stumped
I have only seen specimens of Z. x-notata, so I am going to abstain. Interesting to note, though, that Zygiella spins an orb web with a missing sector, through which it runs its signal line to the spider's retreat. I have never seen one in the hub of its web, though at night it might hang out there. Very common near water.

Thanks Eric
Your abstention has convinced me this is Z. atrica.

reclusive
The time I saw two spiders at the center of their respective webs at night was more of an exception as most webs were devoid of the spiders. They may have been there as a matter of capturing and feeding on small insects that I was unable to descry. It would appear this spider is not comfortable hanging out in the hub.
