Antlions go through a complete metamorphosis, which means they have four life stages: egg, larva, pupa, and adult 🐣➡️🐛➡️🦋. A female antlion lays eggs in sand, which will hatch into tiny larvae. The larvae dig conical pits in the sand to trap insects, especially ants, who fall in when trying to climb out. After several weeks, the larvae pupate in the soil to become adults. Adult antlions emerge and spend time flying around to find mates. They usually live for a few weeks before dying.
