I'm surprised that happened this year, with all those ships and travel. Mosquitos couldn't grasp hiding on cargo ships until now?

  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. But now when it's a bit warmer, the same amount arrives but more survive.

    Also, more time for succeeding populations to have mutations that have better adapted to even the colder climate.

  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. On an entire ship? Probably hundreds of dozens.

    Birds can carry insects or their eggs all over the place too.
