Discovery of Mosquitoes in Iceland Surprises Researchers

For the very first time, mosquitoes have been identified in Iceland, a nation previously known to be free of these insects. This surprising information came from a researcher who spoke with AFP on Monday.

Unexpected Find in Reykjavik Suburbs

A total of three mosquitoes, specifically Culiseta annulata, consisting of two females and one male, were discovered roughly 20 miles away from Reykjavik, Iceland's capital. This was confirmed by Matthías Alfreðsson, a noted entomologist from the Natural Science Institute of Iceland.

They were trapped accidentally while using a method designed to lure moths—wine ropes soaked in sugar. According to the researcher, sugary wine-soaked ropes, when hung outdoors, attract insects seeking sweet treats.

Local Involvement in the Discovery

Local reports indicated that the mosquitoes were found in someone's backyard. Björn Hjaltason, who noticed these bugs on successive days, captured them and forwarded them to Alfreðsson for accurate identification.

Hjaltason told the media, "The fact that three ended up in my garden might mean there could be more around."

A Unique Scenario in the Northern Hemisphere

Historically, Iceland along with Antarctica, is one of the very few places globally without native mosquito populations. This is noteworthy given that neighboring countries like Norway, Scotland, and Greenland do have these insects.

Alfreðsson recalled a past encounter where only one arctic mosquito, Aedes nigripes, was found decades ago, inadvertently brought in by an aircraft at Keflavik Airport. Unfortunately, that specimen is now unavailable for study.

Possible Explanations for the Mosquito Appearance

The presence of mosquitoes could hint at their recent entry into Iceland, potentially by means of shipping routes. Alfreðsson suggests that further observation is required during the upcoming spring to understand their potential proliferation.

Climate change, marked by rising temperatures and milder winters, could create environments more conducive to mosquitoes. Iceland has been proactive in combating climate change via various initiatives.

Climate Conditions and Mosquito Adaptability

Despite these climate shifts, Alfreðsson posits that the discovery of mosquitoes isn't solely due to warmer climates. This specific species appears to withstand cold temperatures well, enduring long and severe winters.

The adaptability and range of habitats in which this species thrives, further aids their survival in Iceland's challenging weather.
