 The exact meaning of the name " antlion " is uncertain . It has been thought to refer to ants forming a large percentage of the prey of the insect , the suffix " lion " merely suggesting destroyer or hunter . In any case , the term seems to go back to classical antiquity . The antlion larva is often called a " <unk> " in North America because of the odd winding , spiralling trails it leaves in the sand while relocating , which look as if someone has been doodling .
