Mosquitoes Found in Iceland for the First Time Amid Record-Breaking Heat
Mosquitoes Found in Iceland for the First Time Amid Record-Breaking Heat
By Joseph Iyaji | Akahi News
In a historic and worrying environmental development, mosquitoes have been discovered in Iceland for the first time — a country long considered one of the world’s last mosquito-free zones. The rare find comes after the island nation experienced unprecedented heat this spring, raising concerns about the broader impact of climate change on fragile Arctic ecosystems.
First Sightings by Local Enthusiast
According to reports from Icelandic media, local insect enthusiast Bjorn Hjaltason encountered the mosquitoes over several nights in the glacial valley of Kjós, southwest of Reykjavík. Hjaltason, who was observing moths using wine-soaked ropes, noticed “a strange fly on a red wine ribbon” and immediately realised it was something unusual.
He later found two female mosquitoes and one male, which were sent to the Icelandic Institute of Natural History for identification. Entomologist Matthías Alfreðsson confirmed the insects as Culiseta annulata — a hardy species known to survive winter conditions in parts of Europe and North Africa.
“The last fortress seems to have fallen,” Hjaltason wrote in a Facebook post that has since gone viral in Iceland, marking the end of the country’s mosquito-free status.
Climate Change May Be a Factor
Experts believe Iceland’s record-breaking heatwaves may have created a more favourable environment for mosquitoes to survive and reproduce. Normally, Iceland’s cold climate and lack of stagnant water prevent mosquito breeding.
However, this year the country endured 10 consecutive days above 20°C, with temperatures peaking at 26.6°C in May — the highest on record, according to the Icelandic Meteorological Office.
A recent study by the Global Heat Health Information Network warned that such drastic temperature shifts could have “significant” impacts on cold-adapted ecosystems, potentially altering insect populations and disease risks in previously unaffected regions.
A Global Climate Warning
The United Nations’ climate body has repeatedly affirmed that human influence has “unequivocally” warmed the Earth’s atmosphere, oceans, and land — a trend now being reflected even in traditionally frigid environments like Iceland.
While it remains uncertain how the mosquitoes reached the island, Hjaltason speculated that they could have arrived via shipping containers from the nearby Grundartangi industrial port. “If three of them came straight into my garden, there were probably more,” he noted.
Further studies next spring will determine whether the species has successfully established itself in Iceland — a development that could symbolise yet another environmental shift caused by global warming.
