- 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.
