These bugs would normally be swarming Florida right now. But they’ve vanished

Florida is known for a variety of potentially dangerous wildlife: Alligators, sharks, mosquitoes, drunken spring breakers, and toxic green slime. Love bugs are generally not on that list.

Are they annoying? Sure. The small black bugs swarm everywhere in the spring and again in late summer, usually in thick clouds. They can often be found with dozens of their friends, smeared across the front of your car. It takes some elbow grease – and, pro tip! A dryer sheet – to wipe them off and preserve your paint job.

But not this year. The love bugs have gone missing.

What are love bugs?

Love bugs, scientific name Plecia nearctica, are small, thin flying insects about a third of an inch long. They resemble small lightning bugs but, unlike their glowing cousins, love bugs only live for a few days. They spend most of that time mating and remain connected even after completing the act, hence their name.

Love bugs do not bite or sting, but the large swarms can get smeared on cars, obstructing windshields and radiators and, if left in place, even damaging paint. They tend to be attracted to light-colored surfaces.

"What they do is just bother people in their cars and houses," Dr. Norman Leppla, a professor at the University of Florida who specializes in entomology, told FOX 35 in Orlando.

Love bugs are not, contrary to popular urban legend, the results of a University of Florida genetic experiment unleashed into the Sunshine State. Records of the insects date back to the early 20th century, starting in Louisiana. 

What happened to the love bugs?

No one is really sure. Their numbers have been declining the last few seasons and many areas have hardly seen any this year – a drop that Leppla called "a little shocking."

"They are closely related to mosquitoes, and we’ve got plenty of mosquitoes, so why don’t we have plenty of love bugs?" he wondered.

Dr. Norman Leppla, an entomology professor at the University of Florida, is puzzled by the vanishing love bugs.

Dr. Leppla suggests the bugs might be going through a pandemic of their own, but since they aren’t a huge problem, there are not a lot of people trying to find out.

"It’s not predators. We haven’t seen any parasites. Could be a pathogen," he continued. "It’s just hard to tell when a population of insects declines. What is the cause?"

Cicadas in 2024

While Floridians are wondering what happened to their love bugs, a different type of insect is already making headlines elsewhere. This year will be cicada-geddon: Two periodic cicada broods – one that emerges every 13 years and one that emerges every 17 years – are expected to coincidentally crawl from the ground together for the first time since 1803.

As billions of bugs emerge, their incessant chirping and abandoned exoskeletons will be hard to avoid this summer, from Illinois on down through the Southeast.  But Florida won’t see them either.

While some cicada species do call Florida home, Brood XIX (the 13-year cicadas) and Brood XIII (the 17-year cicadas) don’t extend that far south.
