The antlions are a group of about 2, species of insect in the family Myrmeleontidae, known for the fiercely predatory habits of their larvae, which in many species dig pits to trap passing ants or other prey. The adult insects are less well known, as they mostly fly at dusk or after dark.
Adult antlions are much larger than their larvae and look like fragile, drab damselflies, with an elongated body, four intricately veined wings.
The adult antlion superficially resembles the unrelated damselfly. It can readily be distinguished.
