Reporters traveling to the United Kingdom for President Joe Biden's first overseas trip were delayed over six hours after their chartered plane was overrun by cicadas.
The Washington, D.C., area is among the many parts of the country suffering under the swarm of Brood X, a large emergence of the loud 17-year insects that take to dive-bombing onto moving vehicles and unsuspecting passersby. There are trillions of them in the Washington, Maryland and Virginia region, said University of Maryland entomologist Paula Shrewsbury.
Even Biden wasn’t spared. The president brushed a cicada from the back of his neck as he chatted with his Air Force greeter after arriving at Joint Base Andrews for Wednesday’s flight.
"Watch out for the cicadas," the president jokingly told reporters. “I just got one. It just got me.”
The plane was scheduled to depart Dulles International Airport around 9 p.m. ET but was grounded due to cicadas in the auxiliary power unit (APU), rendering it inoperative, Delta said in a statement to the NBC News. The APU provides electrical power to the aircraft cabin and other aircraft systems. Ultimately, the plane was swapped for another one, and the flight took off shortly before 4 a.m. on Wednesday.
The cicadas — which sing to attract mates with science-fiction-sounding hums — seem to be attracted to other noises, entomologists said. That could be what happened with the plane.
More Cicadas Coverage
“The loud machine-made noise fools cicadas who interpret the noise as a cicada chorus that they want to join and they fly towards it,” Shrewsbury said. “I have noted when airplanes fly over my house, the cicadas increase their chorusing sound level, potentially competing with the aircraft noise.”
Periodic cicadas are mostly in the United States with two tiny exceptions in Asia. They are not in Europe. At least not yet.
This is not the first time the cicadas have caused havoc for a presidential event or been political fodder.
In 1902, President Theodore Roosevelt, known for a booming voice, was nearly drowned out in an address at Arlington National Cemetery.
Eighty-five years later — five cicada cycles — President Ronald Reagan in a radio address talked about how Washington was overrun and compared the harmless flying insects to big spenders.
“I think most everyone would agree, things will be much more pleasant when the cicadas go back underground,” Reagan said.
In a 2004 attack ad, Republicans attacked Democratic presidential candidate John Kerry, now Biden's special climate adviser, by comparing him to noisy cicadas that disappear.
The three previous White House residents — George W. Bush, Barack Obama and Donald Trump — had run-ins with pesky house flies, said University of Illinois entomologist May Berenbaum. And then there's the fly that perched on Vice President Mike Pence's head during a live vice presidential debate last year, she said.
The press plane is arranged with the assistance of the White House and carries press at their expense. There was not expected to be any impact on news coverage of Biden's visit.
