Yeah, probably this. And the increase in temperature simply made the conditions bearable when they got outside.
Could they have also maybe just… flown over there? Insect migrations like this can happen, but I don’t think it’s possible on such a scale, even for mosquitoes.
Ah, fair enough. To be fair a good couple of spider species were able to cross continents via ballooning, so now that I think about it, mosquitoes doing just as well isn’t too far fetched.

Sand from Sahara in Africa is sometimes carried by wind and rains down in Scandinavia and even South America.
Fish eggs have landed in tree tops in the Amazon and what not.
I’m sure a mosquito or their eggs could ride the wind to Iceland as well.
