A Pit trap is made by an antlion larva, which waits at the bottom with jaws cocked, ready to impale an ant or beetle. In creating the pit, the antlion removes all bits of leaves or twigs, and tosses out the sand in such a way that the pit is lined with the smaller grains which make a more slippery slope. If a prey is struggling up the side of the pit, the antlion flings up sand at it to make little avalanches that carry the prey to the bottom.
Seen in sandy dry areas.
