Amazing Ants Game
For
most of us, ants may all look essentially the same—tiny, nondescript
creatures that scurry around carrying things twice their size. But there are
nearly 10,000 known species, each the unique product of over 140 million years
of evolution. And their behaviors are just as diverse. Below,
meet eight different types of ants with
extraordinary habits and abilities.—Melissa Salpietra

Honey
pot ant Genus:
Myrmecocystus
Honey pot ants have a unique means of surviving in the deserts where they
live—they store excess food in the bodies of some of their workers. Honey
pot workers gather food just like any other ant, seeking out plant nectar,
honeydew from aphids, and similar sweet treats. But when they return to the
nest, these workers feed their
spoils to a specialized class of workers called repletes. The repletes store
the food in their gasters, the hindmost section of their bodies, which have
thin, flexible walls that can distend to great volume. When food is scarce, the
repletes simply regurgitate the stored food and feed the colony.

Leafcutter
ants Genus:
Atta or Acromyrmex
Although their common name suggests that leafcutter ants live off of leaves,
they don't eat them. The ants scissor off pieces of fresh leaves using
their sharp mandibles and carry them back to their nest, where smaller workers
chew up the leaves and make a mixture that includes some of their own feces. On
this bed of vegetable fertilizer, the ants cultivate a certain kind of fungus.
Found only within ant colonies, this fungus feeds the leafcutters, which in
turn ensure the fungus's survival. When a new leafcutter queen sets off
to start her own colony, she brings along a starter-culture of the fungus.

Gliding ant Genus:
Cephalotes
Living in the forest canopy, gliding ants nest within tree cavities. If one
falls accidentally or jumps off its host tree to avoid a predator, it can
actually steer itself through the air. In mid-fall, the wingless ant orients
itself so that its abdomen and hind legs point toward the tree from which it
fell. It can even make 180-degree turns in mid-air. "Controlled aerial
descent," as it is known, ensures the ant won't fall too far from
its nest and become lost.

Bullet
ant Species:
Paraponera clavata
Think honeybees and paper wasps have a painful sting? This ant has a jab that
produces debilitating pain that can last up to 24 hours. P. clavata uses its powerful sting not only as a defensive
mechanism if threatened but also as a weapon while foraging. The indigenous
Sateré-Mawé people of Brazil use bullet ants in a painful
initiation ritual, in which youths on the brink of manhood repeatedly don hand-woven
gloves laced with dozens of live
bullet ants.

Trap-jaw
ant Genus:
Odontomachus
This ant's bite is literally faster than a speeding bullet. The trap-jaw ant, a
stealthy hunter, stalks its prey with its formidable mandibles wide open. When
tiny hairs protruding from its jaw come in contact with its victim, the
ant's mandibles snap shut in under a millisecond. The lightning-fast jaws
also serve another purpose. If closed on a hard, flat surface, they can actually
catapult the ant through the air, a technique the trap-jaw uses to cross enemy
lines.

Army
ant Genus:
Eciton
Unlike most ants, which make long-term nests, army ants are
migratory. They build temporary camps, or bivouacs, out of their own bodies.
Using hooks at the end of their legs, worker ants link their legs together and
create ant chains. These chains layered upon each other create a huge mass of
ants, with the queen and larvae safely in the center. Army ants exhibit group
predation and go on leaderless raids, swarming anything in their path. Not much
stands a chance against these ants, unless it can move out of the way—the
swarm averages a foot per minute. Even large mammals can fall prey to it if
they are injured, tied up, or otherwise immobile.

Weaver
ant Genus:
Oecophylla
These arboreal ants exhibit extraordinary teamwork while building their
nests; even the larvae get to pitch in. Weaver ants make their nests in
treetops by "stitching" leaves together. They begin by forming a
chain using their bodies that stretches from one edge of a leaf to the other.
As ants exit the chain one at a time, the leaf edges come together. Workers
then select larvae of a certain age and carry them to the construction site.
Each worker holds a larva in its mandibles and gently squeezes, signaling the
larva to expel threads of silk. The worker moves the larva back and forth over
the touching edges of each leaf, and like glue, the silk binds the leaf together.

Jack
jumper ant Species:
Myrmecia pilosula
Known as the tigers of the ant world, jack
jumper ants are aggressive and potentially deadly, killing on average one
person every four years in Tasmania. Their sting releases venom that, in some
people, can cause anaphylaxis, a life-threatening allergic reaction. Australia
has about 90 different species of bulldog ant, as Myrmecia ants are known commonly, and all are armed with
powerful stingers. But in Tasmania it is M. pilosula that poses the most significant threat, because
it is common in suburban areas, and Tasmanians love being outdoors.
