As of October 2025, mosquitoes were discovered in Iceland for the very first time, marking the end of the country's status as one of the few places on Earth without a resident mosquito population. Three specimens, Culiseta annulata, were found in Western Iceland, likely arriving via shipping or cargo amidst a warming climate.
Key details regarding this discovery include:
- Discovery Details: The mosquitoes were identified as Culiseta annulata, a species that can survive cold temperatures, found in Kiðafell, Kjós, near Reykjavik in mid-October 2025.
- Climate Impact: The discovery is linked to climate change, with Iceland warming at a rapid rate, making it more hospitable for insects that were previously unable to survive the harsh winters.
- Historical Context: Before this, Iceland was largely considered mosquito-free due to its intense freezing and thawing cycles. Similar species have been found in Greenland and Northern Europe.
- Potential Establishment: While this is the first discovery, it is currently unknown if these mosquitoes will permanently establish a breeding population, as they are now under study to see if they can survive the full winter.
