Three mosquitoes found in a garden in Kjós have become a focal point for scientists watching rapid temperature changes in the North Atlantic. Insect enthusiast Björn Hjaltason discovered the insects and sent them to Matthías Alfreðsson at the Icelandic Institute of Natural History, who confirmed they are Culiseta annulata.
The Iceland mosquito sighting highlights how a landscape of ponds and marshes, combined with one of the fastest-warming regional climates on Earth, can suddenly become suitable for species once kept at bay by cold. Iceland’s seasonal chill has long limited mosquito establishment, but warming trends are changing those boundaries.
Authorities say these are the first mosquitoes recorded on Icelandic soil, though mosquitoes have been found previously on arriving boats and planes. RÚV reported that until this month only Iceland and Antarctica had no recorded mosquito populations; with this development only Antarctica remains free of the insects.
Experts note that Culiseta annulata is not known to transmit disease, but the Iceland mosquito sighting feeds wider concerns about vector movement as climates warm. Scientists point to recent discoveries of Asian tiger mosquitoes in the U.K. as an example of species extending into cooler areas and raising the possibility of diseases reaching new regions.
It remains uncertain whether the discovered mosquitoes will survive Icelandic winters and become established. For countries like Pakistan, the incident serves as a reminder to monitor vector trends and strengthen surveillance and public health preparedness as global temperatures shift.
