Rules:

Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

How'd they get there? Human activity or somehow carried by weather maybe?

[–] jcs@lemmy.world 10 points 1 day ago (1 children)

Any number of places. It could have been a stowaway in luggage, imported livestock, etc.

[–] brachypelmide@lemmy.zip 6 points 1 day ago (1 children)

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.

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.

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.

They probably flew.

Every day animals are adjusting their habits and habitats based on the changing environment.

...or going extinct, like a sizable number of species already had in the last few decades
