Iceland, known for being mosquito-free, now has its first tiny visitors

Iceland, the chilly island nation once proud to be mosquito-free, has officially joined the rest of the world in dealing with the tiny, buzzing menace.

This spring after an unusually long heatwave, mosquitoes have made their first documented appearance leaving locals both fascinated and slightly horrified.

The discovery came courtesy of Bjorn Hjaltason, an avid insect enthusiast with a flair for spotting the unusual. Armed with wine-soaked ropes to lure moths in his backyard, Hjaltason noticed something unexpected: a “strange fly” clinging to his red wine ribbon. Upon closer inspection, he realized he was staring at not one, but three mosquitoes: two females and a male.

“I could tell right away that this was something I had never seen before,” he wrote on a local wildlife Facebook page. “The last fortress seems to have fallen.”

Hjaltason didn’t stop at curiosity. He sent the insects to the Icelandic Institute of Natural History where entomologist Matthías Alfreðsson confirmed his discovery. The mosquitoes belong to the species ‘Culiseta annulata’, one of the few types capable of surviving the harsh Icelandic winters.

Though common in parts of Europe and North Africa, how these mosquitoes arrived on the island remains a mystery. Hjaltason speculates they might have hitched a ride from nearby shipping ports such as Grundartangi, which is just six kilometers away.

For decades, Iceland was a mosquito paradise freezone, largely thanks to its cold climate and lack of stagnant water where mosquitoes could breed. The only other mosquito-free region on Earth was Antarctica. But this year, the country’s weather charts looked more tropical than arctic.

Iceland experienced 10 consecutive days of temperatures above 20°C (68°F) in May; something normally rare and brief. At Eglisstaðir Airport, temperatures soared to a record-breaking 26.6°C (79.8°F) adding fuel to the tiny invaders’ survival chances.

Scientists warn that this is more than just a nuisance story. Iceland’s delicate ecosystems have adapted to its cold climate for centuries, and sudden warming could disrupt the balance. A June study by the Global Heat Health Information Network notes that shifts like these can have “significant” effects on native flora and fauna.

Last year was the hottest on record worldwide, and the UN has confirmed that human activity has warmed the atmosphere, oceans, and land with “unequivocal” impact.

From wine-soaked ropes to breaking climate records, Iceland now has a new claim to fame: the island where mosquitoes finally dared to land.
