Definition
An ant lion (sometimes written antlion) is the larva of insects in the family Myrmeleontidae. They are best known for digging conical pits in sand to trap ants and other small insects. Once prey falls into the pit, the ant lion ambushes it with strong mandibles. The adult ant lion resembles a damselfly but is a weaker flier. Think of them as tiny, sandy pit-building ambush predators.
