Ant Lions are gigantic versions of real life antlions.
Monster Manual descriptions
Giant ant lions are huge insects inhabiting areas of sand and gravel where giant ants and similar large insects are common. Typical habitats are desert fringes, badlands, and areas of rocky terrain. There the ant lions dig tapering pits of about 60 feet in diameter. The pits will look like a cave or lair entrance 50% of the time. Any creature entering these funnel-shaped traps will be 50% likely each round to slip and slide down the loose sides and land at the bottom. Lurking there is the ant lion. It will burst out of the covering of loose sand, gravel, and stones beneath which it has buried itself and attack the victim with its huge mandibles. A hit indicates the ant lion has closed its jaws and will not release its prey until it or the prey is dead. Although ant lions do not collect treasure, there is a 30% chance that there will be 1-3 of the following items in the monster's lair from previous kills: 10-40 gp, 5-20 pp, shields, metal weapons, jewelry, and miscellaneous items.
Ant lions devour 1 or more giant insects each day, carrying the remains away and concealing them. Thus it is possible to encounter one outside its pit.
