Very cool little jumping spider. Obviously at first I thought it was an ant. But, after watching it for a minute its behavior and movements were not ant like. So, I captured it to get better images because it wouldn't hold still. One thing I found interesting is the markings. Notice the white markings on the side of the abdomen, the side of the cephalothorax and the two on top of the cephalothorax.
Also notice, in the last two pics, how it decided to encase itself in web for the duration of its detainment. Why did it do this? Was it frightened and felt more secure this way or was it just making itself at home in the container? Notice the tiny little exit door at one end. Once I finished taking pictures of it I took it back where I found it and used a Pine needle to herd it out of the web.
