No, COVID didn’t ‘kill off’ lovebugs but here’s some reasons why you’ve noticed fewer lately

Scientists say the virus itself didn’t impact them, but some changes in behavior during the pandemic could help explain why you’ve noticed fewer his year.

TAMPA, Fla. — We love to hate them.

Twice a year – around May and September – lovebugs emerge in swarms and then wind up splattered and smeared all over the front of your car as they spend their brief lives above ground paired up in an all-out mating frenzy.

But not this year (not that we're complaining).

At least that’s the observation of many who say they just haven’t noticed the massive swarms and stuck-on bugs of seasons’ past.

Twitter and TikTok are filled with people across Florida asking what happened to the lovebugs?

Some users went so far as to wonder: “Did COVID kill them off?”


Did COVID-19 kill off the lovebugs this year?


  • William Kern, University of Florida, Ft. Lauderdale Research & Education Center Entomology & Nematology Department.
  • Nash Turleybiologist, Penn State University.


This is false.

No, COVID did not “kill off” the lovebugs, but some of the changes in our behavior during the pandemic could help to explain why you might’ve noticed fewer of them.


The virus itself wouldn’t have had an impact on the lovebugs, said biologist Nash Turley, but there are several other possible explanations.

Lovebugs live about six months, he said, but only spend three to four days of that life above ground where we would typically see them.

“So, what influences their population is primarily what happens to their juvenile stages when they live underground,” he said.

This is where rainfall and temperatures can factor in.

Wetter weather during this timeframe is better because lovebugs lay their eggs in rotting, wet vegetation, according to Turley.

If the soil is too dry, or even too wet, it can impact the lovebugs in the months before they emerge.

“It’s more what happened last April, May, June that’s more important to what’s happening now,” he said.


UF entomologist William Kern says a fluctuating lovebug population could also be a product of the pandemic.

Lovebugs, he said, love to swarm near roadways because they’re attracted to the heat and the exhaust fumes from the cars. In addition, decomposing thatch or mowed grass left behind along our roads provides a perfect moist breeding ground for lovebugs to lay their eggs.

“But because of the pandemic people haven’t been driving as much, so we tend to see them less often, or we’re not attracting as many love bugs into those areas,” Kern said.

“The other possibility is because the Department of Transportation has been sort of limited in their manpower, the mowing that is done along the right of way of highways has been reduced, and remember that’s what the lovebug larvae feed on," he added

While there are multiple likely explanations, both Kern and Turley say it’s difficult to pinpoint for certain from season to season what causes fluctuations in the lovebug population because no one is tracking it that closely.

“Any species that have these big emergence in nature, they change from year to year and if someone was studying it really thoroughly from year to year we’d probably have better ability to correlate what environmental factors predict it,” Turley said.

Since lovebugs are more of a nuisance than anything, scientists say it likely isn’t worth the time or money necessary for researchers to closely monitor them.


  • Lovebugs are not native to Florida. They’re an invasive species from Central America and first showed up in the state in the late 1960s, according to UF entomologist William Kern.
  • Contrary to popular belief, lovebugs are not a product of a University of Florida experiment gone wrong.
  • Urban legend says the insects escaped from researchers and then spread rapidly across the state.
  • Lovebugs are attracted to our cars because of the heat, exhaust fumes and vibrations. Kern said the interstates could have served as conduits to bring them around the Gulf of Mexico, through Texas, and into Florida.
  • They are not considered harmful to humans because they don’t sting or bite.
  • Lovebugs have few natural predators.
  • They live for about six months but only spend about three to four days above ground where we see them.
  • Once dead, lovebugs become extremely acidic, which is why they can cause damage to your vehicle’s paint if not removed.
  • They’re called lovebugs because of their mating habits — we often see them attached together in pairs.
