Comments & ID Thoughts
Found: Council Virginia, Buchanan County, in the Appalachian Mountains.
Date: June 4th, 2018. During the day around 3:00 o'clock pm.
Location: In the grass of a yard.
My initial guess is that the spider is a female wolf spider. I guess this due to it carrying a cluster of young spiders on its abdomen. As for the yellow string like thing, I am unsure what that is, I guess that it is of biological origin, but I am unsure.
