The Jerusalem Cricket is not the real Child of the Earth. The real thing is an arachnid. They are reputed to make a noise that sounds like a crying baby but this website makes no mention of that.
Some people in NM are deathly afraid of them. One of my neighbors, when I lived in SW NM, picked up a cinder block and there were two of them living under it in the dirt. He freaked out completely. I didn't hear them make any noise though.
