Meet the Robber Fly or Assassin Fly. This one was following me around in a part of the High Desert we were at. Guy and the dogs of course did not see it, so when Guy asked what I was doing I told him what I found.
This rather large insect seamed to give off that don't mess with me attitude. I really do not know how to explain it. This insect had nothing to worry about I had no intentions of picking it up.
