![]() Adult ant lions live for one to two months. ('Army ant,' by the way, is a term we use to refer to about 150 species of ant, per National Geographic. Upon complete metamorphosis, adult ant lions resemble damsel flies, 1½ inches long, with narrow, net-veined wings they hold over their long, skinny abdomens like pup-tents when they are at rest. It's more commonly known as the 'death spiral.' Army ants are 'practically blind' and rely on each other's pheromones to navigate Dr Morley Read/Shutterstock On paper, army ants are some of the most formidable ants around today. The ant lion, now about a half inch in size, pupates in a spherical, sand-covered cocoon for about a month in spring or summer. The larvae develops in stages called instars, digging many pits, some as large as two inches in diameter and depth.

The ant lion then calmly takes out the trash, flicking the carcass out of its pit, and awaits its next victim. The predator drags its prey deeper into the sand, where it sucks out its body fluids. At some point in the struggle, the insect falls into the bottom of the trap or is impaled by the ant lion’s piercing mandibles. The ant lion further confuses the process by flicking particles of sand or dirt onto the frantic insect, aiding its descent into the pit. Ants end up following the pheromones of one another, and they get stuck like this and eventually they can die of exhaustion. The steep sides make it hard to crawl out. An ant or a small insect steps inside the rim of the pit and begins the fight for life. Once complete, the pit becomes the ant lion’s home for up to three years.Ĭompletely buried now except for its long, piercing mandibles, or jaws, which stick out of the center of the pit, the ant lion larvae lies motionless at the bottom, waiting for its first victim. 1 The phenomenon is a side effect of the self-organizing structure of ant colonies. It has been reproduced in laboratories and has been produced in ant colony simulations. Continuing their backward, downward spiral, abdomen first, the cone-shaped pit is constructed. This circle is commonly known as a 'death spiral' because the ants might eventually die of exhaustion. As they begin excavation, their oval-shaped abdomen plows through the soil, while their flat heads act like a shovel, flicking sand up and out of the pit. Their broad, flattened bodies have short, stubby legs, best for their habit of crawling backwards, which is also aided by the curve of the nearly invisible hairs on their body. The same color as the soil, they are well camouflaged. ( Click here for a video of the ant death spiral in action. They continue to march on in ignorant bliss, unaware that they are marching in a spiral, until eventually, they die. Once hatched, the larvae crawl about in search of a suitable home site, leaving tracks that look like doodles. The column of ants begins moving in a spiral, where the first ant in the column is following the last ant in the column. Adult ant lions lay their eggs in dry, loose soil. Found worldwide in arid and sandy habitats, ant lions belong to the order Neuroptera.
