Antlions are a family of insects, known by the scientific name Myrmeleontidae. "Antlion" usually refers to the larval form of the insect, and they are so named because the larva's typical food is ants, though they will eat other insects as well. Antlions will dig pits in sand inches deep and lurk in the bottom waiting for prey to come close. When the prey falls into the pit, the loose sand on the sides of the pit prevents them from escaping and causes them to fall further down towards the antlion. The antlion's jaws are hollow, and upon biting its prey it will suck out its juices rather than actually eat it. When the antlion is finished, it flicks the husk out of its sandpit and fixes any damage done to the walls, then waits for its next meal to pass by.
