On our evening hike, Karla spotted one of our big black friends trotting across the road. These guys spend a lot of time traipsing through the weeds in search of a willing girl to impregnate. I only got to see that ritual one time, and it was fascinating. First, the girl wasn't black; she was almost cocoa-colored. They check each other out, with her remaining for the most part in her tunnel. He stroked her with his forelegs, then his pedipalps, which look like short forelegs, delivered some sperm (I think that's how it works), then both of the spiders quivered. He was finished, so he backed away and trotted off for more girl-hunting as she backed into her tunnel and disappeared from sight.
A very short romance, indeed!
