Greater European House Spider with egg sac(s) - Eratigena duellica - Female
Bonney Lake, Pierce County, Washington, USA
June 21, 2008
I found this one (among many many others) in the wood pile. It has the bottom of one of the pieces of wood completely covered with webbing. When I peeled the webbing off the see the spider, and I also found this egg sac (or egg sacs?).

Egg Sacs
may not be this spiders. Rod Craword says these usually suspend their egg sacs in webbing.

egg sacs
I have seen some T. gigantea & T. agrestis egg sacs pressed up on the sides of structures like this before. It is far more uncommon for T. gigantea then T. agrestis in my experience, however I have seen it. T. gigantea egg sacs are actually disc shaped when first constructed before they stick random debris and extra silk over it. Because of this they can fit in thin spaces such as this. That looks to be 2 egg sacs next to each other; the size, silk and debris are consistent with T. gigantea.

Thanks
It did seem odd that it would encase itself with some other spider's egg sacs.
