This is a jumping spider that found its way onto my monitor.
I was once bit by a brown recluse spider. I had a big welt on my arm for six months. In those days I killed all spider and had to kill lots of flies and other bugs too. Now, I leave all jumping spiders and daddy long legs. They are safe to me, eat all the flies and bugs which makes me have nearly zero brown recluse food. So, a greatly reduced probability of brown recluse spiders.
