I came across this bug (what I think is a grasshopper of some sorts), Along Simonstown coastline. It was just sitting in the shade on one of the boulders. I took the photo with my cell phone and it made no attempt to flee even though I came pretty close to it. Is it a juvenile of some locust species?

Koppie Foam Grasshopper

Dear Roland,
This is a Koppie Foam Grasshopper,
Dictyophorus spumans, and it has aposomatic or warning coloration to indicate it is poisonous or foul tasting because it feeds on milkweed.  Grasshoppers in the family Pyrgomorphidae are called Toxic Milkweed Grasshoppers or Gaudy Grasshoppers.
