An ant, climbing from the pit of a predatory ant lion.
The predator, buried in sand at the base of the pit, hurls a volley of debris towards its target.
Caught in the falling sand, the ant slides back into the pit.
The ant tries to escape, and again the unseen predator hurls a load of sand into her path.
No matter which way the ant turns, the ant lion adjusts its aim, sending up clouds of sand and preventing the ant from gaining traction on the steep walls of the pit.
In the end, the ant lion wins.
A tight crop of the previous image shows the jaws of the ant lion reaching up around the waist of the ant.
Removed from its pit, the predator is revealed to be little more than a set of jaws attached to an enormous stomach. These fierce creatures are the immature form of a delicate dragonfly-like insect.
The adult ant lion.
From the human vantage point, the ant lion minefield looks less menacing. Each pit conceals a larva at the bottom.
