Ant lions lurk at the bottom of deep, funnel-shaped pits and holes, where they feed on unfortunates who fall in. An ant lion pit is about 60 feet across and about 20 feet deep. A creature that steps on the pit must make a DC 16 Dexterity saving throw or slip and fall into the funnel. It is there where the ant lion waits, buried just under the surface of the ground. When prey falls to the center of the funnel, the ant lion surfaces and attacks, using its mandibles to grab and tear at its prey.


The vicious ant lion resembles a giant gray or brown ant with leathery skin covered in coarse, black bristles. Its deep, inset eyes are black, and its mouth is filled with rows of jagged teeth. Two large silver mandibles protrude just above its mouth. Each mandible has a barb on the inside midway between the creature’s mouth and the end point of the mandible. An ant lion is about nine feet long and weighs nearly 700 pounds.
