tan spider with brown stripe  - Pisaurina mira

tan spider with brown stripe - Pisaurina mira
Hartland, Windsor County, Vermont, USA
September 7, 2012
Size: 1" to1 1/2"
This spider was on an egg sac, which I thought looked like a black-and-yellow argiope egg sac, but this is not a black-and-yellow argiope. 1. What species is this spider? 2. Is it on its own egg sac, which I would assume?

Moved from ID Request.

Looks like Pisaurina mira

Pisaurina mira
Thank you so much for identifying it for me, Ken. Do you happen to know what its egg sac looks like or would you just assume that this must be its egg sac?

This species
carries its egg sac in its jaws for a time...

...and then, when hatching is near, it places the sac in a "nursery web" and stands guard over it. One of the photos in the Guide looks much like yours:

egg sac
It's definitely a nursery web spider, but every egg sac I've ever seen a nursery web spider carrying is about 1/4 the size, if that, and it's white.

Egg sac?
I don't know about the round thing above being this spider's egg sac. It looks too large to me. It might be a gall?

egg sac
Nope, not a gall, but thanks!
