An excerpt:

Fire ants have developed a unique method to keep from drowning.  At first hint of rising water, worker ants gather the entire colony into a ball - sometimes as big as a basketball.  As the water overtakes the mound, the ball rides the flood like a living raft, rolling in the water so all the members can take turns breathing.  When they strike a solid object, be it a swimming dog or your canoe, they quickly swarm aboard.

...

In the South, during the summer, usually after a rain, hundreds of winged fire ants will ascend from their mounds to mate 300-800 feet in the air. The males quickly drop to the ground and die, their only purpose in life fulfilled. The females, now queens, drift downward to start new colonies; on a windy day, this may be as far as five miles away. The queens burrow into holes and begin laying eggs. Two months later there will be several thousand, each queen capable of laying 1,500 to 1,600 eggs a day. In a year, a new colony can be 100,000 strong. A mature colony can contain over 4000,000 ants. The process can repeat up to eight times each summer, spreading the ants 20 to 30 miles a year. There can be 35 million ants per acre that are constantly foraging and will eat anything that sits still for less than a minute - they will find it, kill it if they can, and then try to eat it.

Hmm, there must be a way to turn ants into food.  I mean if they're that plentiful.

Ummmmmm I hope not!
