There are no mosquitoes in Iceland.

Due to colder weather and fewer ponds, the country has no mosquito population …except for one that’s been in a jar of alcohol at the Icelandic Institute of Natural History since the 1980s, when a University of Iceland biologist caught it inside an airplane.

“I chased it around the cabin until I got it… It’s the only mosquito I’ve ever found in Iceland.”
