I saw this creature on a column on my front porch and thought it was a flying insect of some sort. I thought it was some kind of moth and waited for it to fly but the way it moved led me to believe it was some sort of spider but I'm not sure. It has greenish gray and light colored legs and palps(?) that look like moth antennae. It's front legs are as long as its body. I also have 12 seconds of video. I've never seen anything like it before. So... What is it?
