Iceland has confirmed the presence of mosquitoes for the first time in its history. The Natural Science Institute of Iceland identified three Culiseta annulata mosquitoes, likely transported by freight. This discovery is attributed to a warming climate and increased international travel, which have also led to the appearance of other new insect species. Although these mosquitoes bite, they are not known to carry infections in the areas where they are commonly found.

The Icelandic Institute of Natural History has confirmed the first discovery of mosquitoes in Iceland, with three specimens found in West Iceland. The insects were identified as the species *Culiseta annulata* by entomologist Matthías Alfreðsson after being collected by Björn Hjaltason, who initially spotted the first mosquito in a trap. This find is significant because this cold-resistant species can likely survive Icelandic winters, marking the first time mosquitoes have been discovered outdoors in Iceland. Scientists have anticipated their arrival for some time.

Mosquito populations are surging in Las Vegas due to a combination of urban development, climate change, and insecticide resistance, creating a more hospitable environment for these insects. The city is now facing a growing threat of mosquito-borne diseases like West Nile virus and dengue fever, exacerbated by the adaptation of local mosquito species. Researchers have observed a rapid increase in the aggressive daytime-biting Aedes aegypti mosquitoes. Experts emphasize the need for coordinated efforts from local governments to implement effective mosquito control measures, including insecticide monitoring and public outreach, to mitigate public health risks.
