Record-breaking heat in Iceland has led to the country's first-ever discovery of mosquitoes, according to local media. Insect enthusiast Bjorn Hjaltason spotted the invasive species over several nights last week while monitoring moths with wine-soaked ropes. The mosquito sightings have sparked curiosity among entomologists and scientists.
Hjaltason found two female mosquitoes and one male specimen, later confirmed to be Culiseta annulata, a species known for its ability to survive winter in colder climates. Iceland was once considered one of only two global mosquito-free havens, with Antarctica being the other region. The discovery has raised questions about how these invasive insects managed to arrive on the island.
The warm weather this spring, which broke multiple records and pushed temperatures above 20C (68F) for extended periods, is believed to be a contributing factor in the mosquitoes' arrival. Normally, Iceland experiences such heatwaves for only a few days at most. The country's glacial valleys and cold climate have long been considered inhospitable to mosquito populations.
However, as the planet continues to warm due to human activity, scientists are observing increased occurrences of temperature shifts that can disrupt delicate ecosystems. According to recent research by the Global Heat Health Information Network, such changes could have significant impacts on global health and biodiversity.
Entomologist Matthías Alfreðsson from Iceland's Institute of Natural History confirmed Hjaltason's findings, stating that it is unclear how the mosquitoes arrived in Iceland. The World Population Review noted that Iceland's cold climate, lack of stagnant water, and limited breeding grounds contributed to its reputation as a mosquito-free zone.
The discovery serves as a warning sign for Iceland and other areas with similar climates. As global temperatures continue to rise, scientists are watching closely for further signs of invasive species and changes in ecosystems. While it is still unclear if the mosquitoes will establish themselves permanently in Iceland, this event highlights the importance of continued monitoring and preparedness for climate change impacts on local wildlife.
