England Is Being Invaded By a Swarm of Flying Ants That Can Be Seen From Space

Last week, the UK's weather service registered what seemed like a system of rain showers moving along the nation’s southern coast. But it wasn’t rain—it was a swarm of flying ants.

Though it sounds like something out of a horror film or the Old Testament, it’s actually a completely normal phenomenon that occurs in the UK every summer when a bout of hot, humid weather follows a period of rainfall, The Guardian reports. Flying ants decide it’s a good time to mate, and the queen takes to the sky, emitting pheromones that attract males.

From there, it’s survival of the fittest. The queen will out-fly most of her suitors, leaving only the strongest males to catch up and mate with her, which ensures the strength of her offspring. The others either lose their wings and fall to the ground, or become bird food. (The ants produce formic acid in their bodies as a defense mechanism, which may make gulls that eat them seem loopy.)

According to Smithsonian.com, the queen will chew off her wings after mating and fall to the ground to start a new colony, and the sperm she collected from that one flight will fertilize her eggs for the rest of her life (which could be up to 15 years in the wild).

The official, rather-romantic term for the annual aerial antics is “nuptial flight,” but locals often refer to it simply as “flying ant day.” It sometimes lasts for weeks, during which billions of the harmless insects can be seen in the skies.

A representative from the Met Office explained that its weather satellites mistook the ants for rain clouds because the radar detects the ants in the same way it sees raindrops. Dr. Adam Hart, an entomologist at the University of Gloucestershire, told The Guardian that he thinks the reason the radar registered the ants this year was a result of better satellite technology rather than an increase in the flying ant population.

Meet LiLou: The World's First Airport Therapy Pig

There's a new reason to get to the airport early—you might run into a therapy pig who's there to make your trip a little easier. As Reuters reports, LiLou the Juliana pig is a member of San Francisco International Airport's "Wag Brigade," a therapy animal program designed to ease stress and anxiety in travelers.

Aside from her snout and potbelly, LiLou can be recognized by her captain's hat and red "hoof" polish. She spends the day with guests who are happy to take a break from the pressures of traveling. She might comfort them by posing for a selfie, playing a song on her toy keyboard, or offering them a head to pet.

After bringing joy to people's day, LiLou goes home to her San Francisco apartment where she lives with her owner, Tatyana Danilova. In her free time, she goes on daily walks and snacks on organic vegetables. She even has her own Instagram account.

Airports around the world are embracing the benefits therapy animals can bring to customers. The Wag Brigade program at San Francisco includes a number of dogs, and earlier this year, the Aberdeen Airport in Scotland debuted its own "canine crew" of dogs trained to make travelers feel safe and happy. Therapy miniature horses have even been used at an airport in Kentucky. According to the San Francisco Airport, LiLiou is the world's first airport therapy pig.

Sssspectacular: Tree Snakes in Australia Can Actually Jump

Ophidiophobia, or fear of snakes, is common among humans. We avoid snakes in the wild, have nightmares about snakes at night, and recoil at snakes on television. We might even be born with the aversion. When researchers showed babies photos of snakes and spiders, their tiny pupils dilated, indicating an arousal response to these ancestral threats.

If you really want to scare a baby, show them footage of an Australian tree snake. Thanks to researchers at Virginia Tech, we now know these non-venomous snakes of the genus Dendrelaphis can become airborne, propelling themselves around treetops like sentient Silly String.

That’s Dendrelaphis pictus, which was caught zipping through the air in 2010. After looking at footage previously filmed by her advisor Jake Socha, Virginia Tech Ph.D. candidate Michelle Graham headed for Australia and built a kind of American Ninja Warrior course for snakes out of PVC piping and tree branches. Graham observed that the snakes tend to spot their landing target, then spring upward. The momentum gets them across gaps that would otherwise not be practical to cross.

Graham next plans to investigate why snakes feel compelled to jump. They might feel a need to escape, or continue moving, or do it because they can. Two scientific papers due in 2020 could provide answers.

Dendrelaphis isn’t the only kind of snake with propulsive capabilities. The Chrysopelea genus includes five species found in Southeast Asia and China, among other places, that can glide through the air.
