For The First Time In More Than 1,000 Years Of Human Habitation, Mosquitoes Found In Iceland
Mosquitoes have been found in Iceland for the first time as global heating makes the country more hospitable for insects. The country was until this month one of the only places in the world that did not have a mosquito population. The other is Antarctica.
Scientists have predicted for some time that mosquitoes could establish themselves in Iceland as there are plentiful breeding habitats such as marshes and ponds. Many species will be unable to survive the harsh climate, however. But Iceland is warming, at four times the rate of the rest of the northern hemisphere. Glaciers have been collapsing and fish from warmer, southern climes such as mackerel have been found in the country’s waters.
As the planet warms, more species of mosquito have been found across the globe. In the UK, eggs of the Egyptian mosquito (Aedes aegypti) were found this year, and the Asian tiger mosquito (Aedes albopictus) has been discovered in Kent. These are invasive species that can spread tropical diseases such as dengue, chikungunya and Zika virus.
Matthías Alfreðsson, an entomologist at the Natural Science Institute of Iceland, confirmed the findings there. He identified the insects himself after they were sent to him by a citizen scientist. He said: “Three specimens of Culiseta annulata were found in Kiðafell, Kjós, two females and one male. They were all collected from wine ropes during wine roping aimed at attracting moths.” The species is cold-resistant and can survive Icelandic conditions by sheltering through winter in basements and barns.
