  • Context: For the first time in recorded history, mosquitoes have been detected in Iceland. This discovery is linked to a warming climate and increased international transportation, which are allowing new insect species, including these mosquitoes, to survive in the Nordic nation.

  • Detailed Summary:
    • Three mosquitoes (two female, one male) of the species Culiseta annulata were confirmed in Iceland by the Natural Science Institute.
    • These mosquitoes were likely transported via freight and have demonstrated an ability to withstand Iceland's climate.
    • The discovery was made by an insect enthusiast on a farm north of Reykjavík on October 16th.
    • The species Culiseta annulata is common in Europe and other Nordic countries, known for its ability to tolerate cold weather and often found in sheltered locations like outbuildings and basements.
    • While these mosquitoes can bite and are considered a nuisance, they do not carry known infections in the regions where they are found.
    • This finding highlights the impact of climate change, with the Arctic warming significantly faster than the global average, facilitating the expansion of species into previously inhospitable areas.
    • Globally, over 3,000 mosquito species exist, some of which are vectors for serious diseases like malaria, dengue fever, and West Nile virus.
    • Antarctica remains the only continent currently believed to be free of mosquitoes.
