For the first time ever, mosquitoes have been found in Iceland. Researchers identified two females and one male Culiseta annulata. They were discovered at a farm in Kjos, near Reykjavík.
The insects were trapped on a red wine-soaked ribbon used for butterflies. Their presence signals a potential ecological turning point for the island.
Why Might They Be There Now?
Recent record heat in Iceland may explain the insects’ arrival. Scientists suspect climate change is altering the island’s environmental thresholds. Hotter summers and milder winters could now sustain temporary mosquito populations. Some species, like Culiseta annulata, already tolerate cool northern conditions well.
How They Evaded Iceland Until Now?
Iceland’s cold, windy climate kept mosquitoes from surviving before. Mosquitoes require stagnant, warm water for breeding and larval growth.
Frequent temperature drops previously made their survival nearly impossible. Experts long believed Iceland was one of the few mosquito-free places.
Unknown Future for Iceland’s Ecosystem
Whether these mosquitoes can establish a lasting population remains uncertain. They may have arrived accidentally via freight or human transport. Researchers will monitor future mosquito sightings to confirm permanent settlement. If established, it could reshape Iceland’s ecological and health landscapes.
