Antlion, also spelled ant-lion and ant lion, is a name applied to a group of about 2,000 species of insects in the family Myrmeleontidae. The most well-known genus is Myrmeleon ("antlion"). Strictly speaking, the term "antlion" applies to the larval form of the members of this family, but while several languages have their own terms for the adult, there is no widely used word for them in English. Very rarely, the adults are called "antlion lacewings". The antlion larvae eat small arthropods – mainly ants – while the adults of some species eat small pollen and nectar, while others are predators of small arthropods in the adult stage too.
