We were cleaning up in the front yard this morning, and came across a recently deceased Palo Verde Root Borer Beetle.
The one I found back in March was scurrying for cover, and I was only able to get two photos before it disappeared.
This one was much easier to photograph.
Close-up photos show the spikes on the carapace ...
... and the impressive chomping mandibles.
If these things were the size of a German Shepherd, they would probably rule the world.
