Haven't seen a spider quite like this fella. When he thought the camera got too close, he started doing a wild, agitated dance (last photo). He was fairly small, perhaps the size of a sowbug killer, but less compact.

This was an interesting sighting over an extended period of time. This orbweaver had constructed her web just above head-height on my front walkway, so I was able to watch her at my leisure for several days. During part of this time, she was being courted - very carefully - by a male hoping to mate with her (and get away with his life, I'm guessing). Mostly, he stayed near the edges of the webs, tentatively tapping on threads. then he would move slowly toward her, testing the thread along the way, clearly ready to retreat if she became aggressive. It was super cool to watch. I wasn't able to watch long enough to see the outcome, but hopefully things worked out.

Male/male fight: 2 well matched males battle for more than 15 minutes. I did not stay to see the end of their competition, or if either got injured. They circled each other and moved in side by side. One would bite the other's leg, or tail and the bitten lizard would spin to try to dislodge the biter. Link to video: https://www.youtube.com/watch?v=vjeVkN5rfgo
