Spring Spider Baby Ball

This isn't a post for the squeamish or faint of heart. 

I suggest anyone with a spider phobia (Auntie J)  just not look........... 

But these little guys are soooooooo frackin' cute!

Mr. Jimmy and I spotted this little ball of spider joy hanging off the side of the front porch this weekend. Mom said she's been watching it for a couple days.

This is how far away the wee ones have skittered while we watch them. We saw these ones emerge from the cluster in a dizzying show of speed and agility. 

I asked James to put his hand under the web so I could focus. These little guys are almost too small to get a clear shot.

Here they are without the hand background. I wonder how many of these guys will actually make it out there in the big wide wilderness of our yard. Does anyone know what kind of spider they are?
