Itsy Bitsy Spider

I seem to be fixated on spiders but they are so prolific this autumn.  I went to look at the last of the cone flowers and a movement caught my eye.  An itsy bitsy spider, almost a translucent white with brown, stripy legs, was hard at work connecting all the petals with a very fine web.  His legs were quite the blur.  Finally, it scampered up a nearly invisible web to the bush behind.  What an amazing wee creature to watch.  I wasn't able to identify it unfortunately.
