Honestly I am calling them Scarabs because it sounds more exotic, more desert-like but they look like big black beettles!
They too are night creatures, considering how hot it is in day time it is hardly surprising.
All night long they seem to run around, up and down dunes and in the morning the dunes are covered with their tracks. Then in the morning they try desesperately to bury themselves. Those that came to the lights on location find themselves in sand too thin to find a spot and typically end up stomped on anyway. When I see them in the desert in day time, they run towards me. I think that associate creatures with both shadow and potential moisture, I don't know.
