Ant Lion

The Little Five

Behind the stones, hidden in the grass, and high on an Acacia branch live the Serengeti's Little Five. They may not be the charismatic mega-fauna that the Big Five are, but for the connoisseur of wildlife or the connoisseur who wants an alternative safari, the ant lion and the RHINO beetle are a fascinating alternative, as well as ELEPHANT shrew and BUFFALO weaver or the LEOPARD tortoise.

 
Ant LION

The grazers are lined up and plodding slowly on, migrating back toward higher food and pleasant pastures. One of the masses, distracted for just a moment, steps into a sloping hole. The animal pushes back, trying to regain its footing, but the slope gives way under its weight. It holds on with another leg and pushes again, succeeding only in sliding now into the conical hole beside it. It raises its head in alarm and tries to walk out of the hole, the sand slipping and sliding all around it.
Suddenly, behind it at the bottom two long hairy legs protrude. The hapless animal now runs forward up the slope and is covered by a violent shower of sand landing on and in front of it. It is running for all it is worth, legs pumping, and the creature behind it scooping up great clouds of sand and throwing them up the slope so that they slide down on top of the victim. As the grazer reaches the bottom of the slippery slope, the pace of things picks up; legs are pumping up and down, frantically trying to escape, while the sand becomes a fountain of earth directed up the slope.
It is at the bottom, running with everything it has, when a hooked, hairy arm reaches out, grabs it and drags it flailing into the bottom of the hole. The ant sinks below the sand and the struggle is over.

I have been lying on my stomach in a sandy corner of a dirt road in the dawn hours finding out just how the ant lion catches its six-legged prey. Ant lions are specialized insects that dig a conical hole about an inch and a half across into sandy soil and then hide in the sand at the bottom. By blowing on the sand, the ant lion is exposed. The ant lion stage of this insect's life is actually a larvae that looks a bit like a beetle, but with large mandibles and a small head. The adult that will later emerge is a flying insect that looks like small dragonfly.
When unsuspecting ants stumble into the sandy cone, or are dropped in by me, they run and slide on the sandy cone's sides. The ant lion feels the vibrations of the running prey and emerges to throw sand above and in front of the ant. As the sand slides down the slope, so does the ant, eventually to be grabbed and dragged inside the lair of the fearsome "Simba of the Sand".
