Check out this jumper!

I saw a dead earwig in a web and was taking pictures of it...then realized who's web it was. This jumping spider was amazing, it kept inching towards me, flashing it's red butt, then coming at me. It was definitely threatening me, challenging me. I just googled this guy to figure out what he was, he is Phidippus johnsoni, the Johnson Jumper, or Redbacked Jumping Spider. One of the distinguishing characteristics, besides the obvious red abdomen, are the metallic green chelicerae, which can definitely be seen if you are looking for them. It is a male, the females have a black stripe down their abdomens. I saw two males today acting aggressively towards each other.
