The full grown insect was nearly three inches long. Since all wild African wildlife is new to me, sighting these things amazed me almost just as much as seeing an elephant on the safari!
The armoured Ground Cricket (Acanthoplus discoidalis) also known as an armoured bush cricket or Gobabis prawn is considered a crop pest - eating grain and other sorts of plants. They also eat dead insects, including the dead of their own kind (they are famous for this). The pest control was to have the children step on as many as possible; however, now children go to school and this is no longer effective, so pestisides have come into use. A better approach is to harvest the crops before the next generation of eggs hatch and till the fields before the next generation comes up. Spraying the fields has been ineffective, but baiting the crickets off the fields and into poison has been effective.
I've heard of a spider that eats these crickets and also a few birds, including the stork, but the birds will only eat them at certain stages in their lifestyle. I was amazed at how many of the crickets I'd find in places - and then absolutely none in others. Another interesting (caution: this may be gross for some) was that since the body is so hard, their heads seem to pop off before the body is crushed. Inside is bright yellow, much like the inside of a chocolate Cadbury cream egg. With the head connected only by this goo and hanging down or missing, the legs walked back and forth as if trying to figure out what was going on. This happened a few times to a handful of the thousands of crickets we rode through on bicycle - a few were unavoidable. Another member of the group I was with reported seeing cricket heads floating down the river, expected to be the remains left over from a bird feast.
I've looked on the Internet for other pictures of these guys and the others seem more brown. The ones I came across (in the North of South Africa and Botswana) were clearly blue, slightly purple with bright orange eyes.

Amazing nature capture - looks like something from an animated film or something - especially with those intricate patterns and colors over the body, and its eyes.

aha, I wondered what these were.....
We witnessed them all over Kruger a few months ago. My GF called them "robot" bugs which adequately describes their motion. We often saw them rushing out to retreive a dead comrade. Off to eat them no doubt. Was hard to actually dodge them on the road. they were everywhere.
