The larvae of the antlion spend their life underground. They create a kind of pits, by burrowing backwards into the sand. The larva buries into the bottom of the pit, but leaves its jaws sticking out. When unsuspecting insects, mostly ants, but also woodlice, spiders and millipedes pass by the pit, the antlion starts to flick sand at them until they fall in. They are grabbed by the huge jaws, sucked dry and then tossed out of the pit.
