The antlion efficiently grabs the ant with the long mandibles. Once seized, the ant is quickly pulled under the surface, paralyzed, and then sucked dry. When done eating, the antlion throws the shriveled carcass out of the crater with one last flip of the head.
Antlion pits in dry, loose soil. An antlion makes several pits and repeats the feeding process several times as it grows and develops over a period of time that may last a long as 3 years.
Pits of different sizes do not necessarily indicate the size of the insect. Few people are ever fortunate enough to see the antlion.
They are difficult to find because they spend so much time motionless at the bottom of the pit. Also, they are tan or brown dirt-colored and usually camouflaged with a thin layer of dust or sand that clings to their surface. They are easy to overlook. The best view of the larvae is achieved by sifting them out with a tea strainer.
Just scoop up an inch or so of soil from below the bottom of the pit and shake away the soil. The body is wedge-shaped, with the head narrower than the abdomen. The antlion will walk backward in circles, gradually forming the sand into the shape of a funnel, and then bury itself at the bottom. Catch a few ants and place them in the pan or cup, and watch what happens!
Not all members of the family Myrmeleontidae make pitfall traps. Some hide under vegetation, and others inhabit dry tree holes or even tortoise burrows. In North America, the seven species of doodlebugs that make sand traps belong to the genus Myrmeleon.
Antlions can spend up to 3 years in the larval stage, and the doodlebug will overwinter buried in the sand. Eventually, the doodlebug will pupate within a silken cocoon, encased in the sand at the bottom of a pit. Actively scan device characteristics for identification. Use precise geolocation data.

A ntlions belong to the family Myrmeleontidae and include over described species. Two of the most common genera in the southwestern United States are Myrmeleon and Brachynemurus. Like many other members of the order, adult antlions are commonly seen around lights and campfires, particularly during the late summer and fall. They have two pairs of long, narrow, many-veined wings and a long, slender abdomen. Although they greatly resemble small and unrelated dragonflies, called damselflies, they belong to an entirely different order of insects.

You may call them by their innocent-sounding name of Doodlebug, but they are antlions — voracious predators of ants and other insects who fall into their traps. And it is the larvae that wait at the bottom of a shallow pit for their prey to fall in and provide an immediate meal.
