The larvae of this insect dig cone-shaped holes in fine, dry sand, which they use to trap ants, which they feed on. They throw sand at ants that are trying to escape from their traps in order to make them fall to the bottom of the pit, where he antlion larva will eat it. Care should be taken when walking in dray sand areas to not step on or damage antlion pit traps as the larva can die of exhaustion if it has to re-excavate it too often.
