When Stephen Yanoviak visited the jungles of Panama in 1998 to study how ants forage, he found himself with some unexpected downtime. "Out of boredom, I started flicking some ants off of a tree," he said.
And he saw something extraordinary. Some of the ants fell straight, but others swerved at near-right angles and landed on tree trunks feet from the ground.
Dr. Yanoviak, a University of Florida entomologist, forgot about the bizarre insect gliders until several years later, when he was assaulted by the same ant species, Cephalotes atratus, during a mosquito-collecting trip to the Peruvian rainforest.
"I was sitting on a branch and they were crawling all over me, so I tried to push them off," he said. "They fell, but immediately turned around and glided right back to the tree trunk. That's when I realized this was something worth investigating."
After returning from his trip, Dr. Yanoviak mentioned the gliding ant sighting to his colleague Robert Dudley, an animal flight expert at the University of California, Berkeley. "I thought it was the most exciting thing I'd ever heard," Dr. Dudley said, and he decided to join Dr. Yanoviak in exploring this uncharted biological territory. Since then, their research has shed light on the airborne survival strategies many wingless insect species have, and on the question of how insect flight originated.
With the entomologist Michael Kaspari of the University of Oklahoma, the two took video of the ants' descents, looking for clues about how their structure and movements enabled complex aerial maneuvers.
The ants' hang time was impressive not because their bodies were particularly aerodynamic, but because they knew how to move their long limbs around to reduce drag. They moved their left hind legs outward and rotated them, an off-kilter motion that allowed them to maintain altitude.

"When the researchers covered the insects' eyes with dots of white nail polish, however, they sank to the forest floor like stones."
Ouch!!
"Ummmm, wasn't that the 1953 version of War of the Worlds?"
Nope. At the end of "Them," when they're bombing the dam, that's the plane in the flyby shot. Check it out.
Giant irradiated bug movie trivia question: Who is the famous actor who started his film career as a jet pilot in 'Tarantula'?
That would be Clint Eastwood, although he did not receive a credit in the film. I cheated, though: I looked it up.
When I was a little kid, I used to scoop one anthill with a bucket, retrieving thousands of ants, and then dump them on a different anthill on the other side of the yard. A massive battle would then ensue.
> It was in that "War of the Worlds" movie.
Nope. "WotW" used the B-49. B-35 had props, B-49 had jets.
Dunno what plane "Them" had.
...which has the distinction of being the FIRST giant radioactive insect monster movie, for you film buffs!
"Dunno what plane "Them" had.
"
Yes. The plane in "Them" had pusher props, if memory serves. I'm pretty sure it was the XB-35. It's sort of fixed in my mind, but I'm going to have to order "Them" and have another look.
If it was a flying wing with four pusher props... it was a B-35. It it was a flying wing with jet engines, it was a B-49. If it was a flying wing with jet engines and two underslung jet engine pods, it was a YRB-49 (built from B-35).
My brother Raymond was ahead of his time.
The ones in Congress do. They use airlines.
Only drones and queens have wings - workers never do.
