It looks like it might be a locust borer. Maybe they decided to try some mesquite.

I know the cottonwood version can cause terrible damage in a short amount of time, killing a lot of trees. You might want to get some Tempo (or something of the like) after these guys until you can heat the boards up.
Good luck.
