Information found at BugGuide.Net. Here is another picture of 'Momma'. Here and here are two more pictures of the spiderlings.
After looking at these shots on BugGuide.Net, it seems you may have had more potential to capture the seemingly vivid green of this spider. As for the shot of the spiderlings, I think a different crop may have made it a better shot, if possible.
Perhaps a little blurry, but this is a great capture. You really ahd to be ther at the right time to get this. Nice job. Another shot I would love to see a tighter crop before resizeng - bring those little buggers right up and in your face. Again,great capture!
