Folding-door Spider - Antrodiaetus pacificus - male

Folding-door Spider - Antrodiaetus pacificus - Male
Enumclaw, Unincorporated King County, Washington, USA
September 2, 2009
Size: approx 1" w/legs
This really looks like Antrodiaetus pacificus (should check under a 'scope, though). They were out and about in the middle of the night right after fresh rain. I ran into four others that same night within 30 minutes of each other and all were males out on the hunt for some ladies.

Great bug
wish we had these in NJ!

They're great...
...and usually easy to photograph because they will sort of get 'startled' when you shine a flashlight on them and hold still for a bit. It just takes some good 'ol night hunting with the Mag-Lite. But I've only found males (I don't think the females wander too far from their hole/lair).

Night hunting
I find most of my bugs at night, too. I go to the porch lights about an hour a day (maybe 100 pix). Very relaxing at the end of the day. I guess it is lazy to wait for them to come to me, maybe I should look around, but I'm out to 12:30 or 1:00 as it is (wonder if the neighbors notice!), then there is sorting and IDing. I need more time to post but I get tired at 2:00. Come on hard frost!


Moved from ID Request.

I'll email this to Rod as well.

From Rod Crawford:
This is probably correct. The only other thing it could be is pugnax,
and the season strongly favors its being pacificus. That's precisely
the week when King County male pacificus wander.

Thank you
for your help! I am new to BugGuide and I am amazed and in love with it! You have all been so helpful! Am I right to assume that Lynette is the editor for my area? She is so helpful and responds very quickly! I wasn't expecting that when I first decided to register for the site. Thanks again!
