Mosquitoes Found in Iceland for the First Time

Strategic Insights -

Three Culiseta annulata mosquitoes, a species of mosquito previously unknown in the island nation, have been spotted around 30 kilometers north of Reykjavik, the capital of Iceland. The discovery was made by Matthias Alfredsson, an entomologist at the Natural Science Institute of Iceland, who collected the mosquitoes from wine ropes used to attract moths. This marks the first record of mosquitoes occurring in the natural environment in Iceland, a country that has long been considered mosquito-free, alongside Antarctica.

Key Takeaways:

  • The three Culiseta annulata mosquitoes were collected from wine ropes aimed at attracting moths, a method used to entice sweet-toothed insects.
  • The discovery indicates a recent introduction to Iceland, possibly via ships or containers, but further monitoring is needed to determine their spread.
  • The species appears to be well adapted to colder climates, allowing it to withstand long and harsh winters.
  • Rising temperatures, longer summers, and milder winters due to climate change create a more favorable environment for mosquitoes to thrive.
  • The diverse breeding habitats of the Culiseta annulata species further enhance its ability to persist in Iceland's challenging environment.
  • The discovery highlights the potential for mosquitoes to thrive in areas previously considered inhospitable due to climate change.
  • A single Aedes nigripes specimen (arctic mosquito species) was collected in Iceland many years ago from an airplane, but this specimen is now lost.

Statistics:

  • Three Culiseta annulata mosquitoes were sighted around 30 kilometers north of Reykjavik.
  • The mosquitoes were collected from wine ropes used to attract moths.
  • The species appears to be well adapted to colder climates, with the ability to withstand temperatures below freezing.
  • 20 miles is the approximate distance from Reykjavik where the mosquitoes were found.
