Pacific Northwest male arachnid - Eratigena duellica - male

Pacific Northwest male arachnid - Eratigena duellica - Male
Vancouver, Clark County, Washington, USA
August 29, 2006
Size: 2.5" dia
I've seen many big guys running around both outside and inside my home here in Vancouver, Washington, USA. This one I was able to scan intact. It was found in the middle of the floor this morning without obvious trauma or damage that I could see, but not moving. I have 2 cats and perhaps they played with it and that had something to do with it's demise cause it sure was not there last night.

Please note that the color balance is off as the scanner over saturated the light. It is shades darker.

Thank-you all for your help :D

I hope its a "giant house spi
I hope its a "giant house spider" I live in Vancouver, WA. The other day, I found a hobo spider running on my carpet towards me like it was going to attack :) but it was probably just looking for a mate.

ID
It might be Tegenaria duellica (formerly gigantea) in the Agelenidae family. It's an introduced spider than doing well. There are other possible species of Tegenaria or even some other Agelenopsis spp. around now. It's getting to be mating season for these late summmer species and it is usually the male that is seen running around cruising for females.

 
Yes, T. duellica
I think you have reached a concensus that it is a T. duellica, but just in case... I'll confirm that this is a T. duellica (Greater European House spider). This is the only Tegenaria sp. in the US/Canada that gets to this size (especially with this kind of "leg length to body length" ratio).

Here is the guide page for this beauty...

Thanks for posting a great image for relative size comparisons!

 
Wow,
it really has long legs. You can see a comparison shot to the above mentioned species here.
