Fun facts

1

Its bumpy wing cases gave it its scientific name, which means warty.

2

It is most active at dawn and dusk, when the desert is not so hot.

3

Its larvae can ooze a sticky liquid that glues sand to their bodies, so they are harder for hunters to see.

4

It is very hard to breed. A zoo in the United States worked for four years before it raised its first grown-up beetle.

5

Lots of people keep it as a pet because it is calm, tough and lives a long time.
