I am surprised that I should be surprised. Aren't mosquitoes a well known nuisance in Greenland, which despite the name is colder than Iceland? I would have expected that mosquitos in Iceland were also entirely normal. TIL.

Siberia is also known to have just extremely brutal mosquito seasons. Turns out even -40C isn't enough to do away with the little persistent blood suckers.

I've read that there are tribes who spent a month or more at the peak of biting insect season hiding in their tents and filling them with smoke. The bugs swarm so thickly that they can kill cows. Not by biting them to death, but by clogging their nostrils until the cow suffocates.

Not surprising at all to me after several summer trips to interior Alaska. The mosquitoes are so thick that you inhale them sometimes; which is so disgusting. I slathered myself in Deet (the only thing that works) and was mostly ok. Even then they find every square mm that you missed. I sat down for 30 minutes on a bench leaning forward talking to some people. My shirt pulled up about 1/2” (12mm). Later I counted 137 bites (some had merged due to swelling) across that strip of exposed flesh!

Interior British Columbia sounds similar. I used to work in the forest and they were so persistent, invasive, and aggressive. You had to just stop caring because they were relentless and virtually unstoppable. They'd end up in your clothing, in your hair, your nose, mouth... Sometimes the itch was so severe it burned.

I don't miss that. It usually peaked and calmed down with the season, but if it was warm enough they were always around.

kgeist10 hours ago
From what I know, Siberia's mosquitoes are even more brutal than those in the more temperate regions of Russia, and there are far more of them. Iceland's lack of mosquitoes doesn't seem to be due to the cold itself; something else must be at play. Iceland's average winter temperate is around -1C.
EasyMark4 hours ago
Much shorter breeding season so maybe evolutionary selection made them even more aggressive than the typical US swamp mosquito. The worst I've ever encountered here in Texas some kind of deer fly, and they're tough and bloodthirstily agressive. I have backhanded them 20ft and they come back for more.

>Tx. rutilus feeding behaviors make them strikingly different from a typical mosquito. Both adult males and females are strictly nectar-feeding and so they do not have a role in the transmission of pathogens to animals as in other mosquitoes.[7] Instead, their larvae are predacious and could potentially help curb the spread of diseases via vector mosquitoes. While they commonly prey on copepods, rotifers, ostracods, and chironomids, they also generally have a preference for certain species of mosquito larvae including common disease vectors such as Aedes albopictus, Aedes aegypti, and Aedes polynesiensis.

Nosquitos themselves can't survive when it goes below freezing, but sadly their eggs are nearly indestructible. Siberia, Alaska and the northern parts of the Nordics are absolutely plagued with them in the summer, since snowmelt creates huge amounts of stagnant water that melts the eggs in a perfect habitat for breeding.

dec0dedab0de13 hours ago
The species in the article is already adapted to cold weather. They will find out in the spring if it is adapted well enough to survive the icelandic winter

It is remarkable this is the first time mosquitos have been found in the wild in Iceland though. Even if they died out in the winter, you would expect some to hide in shipping containers and lay eggs all summer. Which is how we got Tiger Mosquitos in New Jersey, and now it doesn't get cold enough to kill them and it is so much worse than it used to be.

cogogo12 hours ago
Saw a tiger mosquito for the first time in Boston last fall. Reported it to the state but it is a losing battle and they are steadily establishing residency. Back again this season so a moderately cold winter still did not kill them off. They are extremely annoying as their primary prey are humans and they are very good at biting you without noticing - then comes the itch. Especially in late August into Oct.

The big thing with insects is going to be less about how they got there and more about whether they can survive a typical winter. Those of us in colder regions don't realize how spoiled we are for just having to wait three months for some of the worst pests to expire. Or plants for that matter.

Could also be that mosquitos always managed to hitch a ride, but in so small numbers that they disappeared relatively quickly once they arrived, or it simply was too cold but some always appeared.

In order to produce a breeding population, several mosquitoes need to hitch a ride on the same ship and stay close enough together that they can mate after arriving. They also need to survive the trip over without that much food. I imagine its quite unlikely.

Strong disagree. One auto tire with a few cups of stagnant water can easily have dozens of larvae.

I live in an area where we have these[1], and they're generally not something you see all that often.

They aren't overly aggressive snakes, and I've encountered them several times over the years.

Alon with bullsnakes, they're extremely useful for getting rid of said rodents—which CAN carry awful pathogens, like hanta virus!

The serious proposals to eliminate mosquitoes only propose to eliminate the mosquito species that carry nasty human diseases. If those species were eliminated other mosquito species would quickly expand to replace the eliminated species.
