Mosquitoes Discovered in Iceland for the First Time!
For the first time in recorded history, mosquitoes have been discovered in Iceland — a country long known for being mosquito-free…oh boy! This surprising find has caught the attention of scientists and climate experts around the world.
Here’s what happened…
Earlier this month, three mosquitoes (two females and one male) were captured in a garden in Kjós Valley, just north of Reykjavík. The insects were identified as Culiseta annulata — a species that can tolerate cold conditions and is commonly found across Northern Europe.
The discovery was made by local insect enthusiast Björn Hjaltason, who had set up a homemade trap using red wine-soaked ropes. He was initially trying to attract moths, but what he found instead was far more unusual. The specimens were later confirmed by entomologists at the Icelandic Institute of Natural History.
Why is this a big deal?
Until now, Iceland and Antarctica were among the few places in the world without mosquitoes. The country’s harsh winters and sudden freeze–thaw cycles have always made it impossible for mosquito eggs or larvae to survive. This new finding suggests that those barriers may be changing.
Experts believe that warming temperatures linked to climate change are the likely cause. Iceland is one of the fastest-warming regions on Earth, and milder winters could be allowing cold-tolerant species like Culiseta annulata to survive where they once couldn’t.
The Role of Climate Change
In 2025, Iceland experienced its hottest May on record, with temperatures well above average throughout the summer. These extended warm periods create ideal conditions for mosquito breeding and development.
Researchers also note that global travel and trade could play a part. Mosquitoes — or their eggs — may have arrived through cargo shipments or aircraft, and with the right weather, managed to survive.
What Type of Mosquito Is It?
The good news is that Culiseta annulata is not known to transmit major mosquito-borne diseases like malaria, dengue, or Zika. However, its arrival is still a warning sign of how shifting climates can affect ecosystems, even in the coldest corners of the world.
Whether mosquitoes will be able to establish a permanent population in Iceland remains uncertain. Scientists will monitor the area closely next spring to see if breeding occurs.
Why It Matters Beyond Iceland
This event highlights how insects are adapting to a warming planet — and how quickly new regions can become vulnerable to species once thought impossible to host. For countries like Australia, where mosquitoes are already a concern, it’s a reminder of how global patterns are shifting.
More warm-weather pests could appear in unusual places, meaning prevention and protection will remain key for outdoor lovers everywhere.
Key Takeaways
Iceland has officially lost its “mosquito-free” status.
The discovery is linked to rising global temperatures.
The species found is not currently a public health threat.
Ongoing monitoring will reveal whether mosquitoes can survive Icelandic winters.
It’s another clear sign of climate change influencing ecosystems worldwide.
