Ant lions are small insects that dig funnel-shaped depressions in sandy areas. They hide in the dirt at the bottom of the funnel. When an ant climbs into the funnel, the ant lion feels the dirt shift and lunges out to grab the ant, shaking it death and then eating it.

The species being fed on are the prey while the species being fed is the predator. In this context, the prey is the ant and the predator s are the ant lions.
