Then while I was trying to coax the snake into sitting still for a photo, Brenda saw a rock move. Only it wasn't a rock, it was a rock lobster! Well, actually it was a short-horned lizard. So it all goes to show that you should be sure to stop and smell the scorpions. Or something like that.


After two nights of road-cruising for snakes in which I had failed to see a single live snake, my luck began to turn when I found a small nightsnake crossing the road. Within an hour or so I also saw two young glossy snakes. Not a very good night for snakes at Anza-Borrego, but a big improvement over none at all.
The taxonomy of this species has been revised numerous times in recent years. I don't think the dust has settled yet, but I'm using the taxonomy described in SSAR names, so I'm calling it H. c. deserticola. Until recently the U.S. nightsnakes were considered part of H. torquata, but that species has now been more narrowly defined such that it exists only in Mexico.
