At the bottom of a sandy pit lies a bristled horror with enormous, hooked jaws. It looks like a fat-bodied louse but is the size of a warhorse.
A giant ant lion is the larval form of a giant insect that resembles a dragonfly. It spends almost its entire life in larval form, voraciously consuming giant ants or anything that stumbles into its trap.
Giant ant lions are perfectly adapted to trapping and devouring prey. They dig slippery pits in loose sand and hide themselves at the bottom, with only their outsized jaws protruding. If a creature comes too close to the pit's edge, it falls in and slides toward the waiting predator. A giant ant lion is expert at knocking down hapless creatures that try to escape the trap, and its body has thick, forward-pointing bristles that keep it from being pulled out of its pit once it has seized its prey.
