Canadian mosquitoes have evolved to be large, aggressive, and highly effective at locating hosts, with a seasonal life cycle where they die off completely in winter and only reproduce during the approximately 4-month warm season, creating intense selective pressure for aggressive blood-seeking behavior.

Canada has big aggressive mosquitoes (but no diseases) - 166 days left until we move to Việt NamAdded:
It is May 15th, 2026 and uh we've had some pretty good weather the last few weeks last days last whatever, but uh today is the beginning of May long weekend.
Today is Friday. Tomorrow be uh Saturday, Sunday and Monday is a long weekend and this morning we had super cold weather and uh this is a not a joke, but uh you know, in Calgary everybody knows that on May long weekend it's going to snow. So, we've had like plus 20 weather for about 2 weeks and almost actually every year that I've lived here for the last 40 years it snows on uh May long weekend and if there's an odd exception you nobody really remembers it because it just seems to be the rule.
So, so tomorrow is supposed to be almost almost down to zero and uh the high is going to hit like 5°. So, that's fun, but on the upside well, I had to do some work down in a area of the of the city that was more naturalized, so I was walking through some natural areas and there were so many mosquitoes and the mosquitoes here are not like in Asia.
The mosquitoes here they are really big and really aggressive and they can home in on you in like like that. Like if you walk around, you'll have a hundred on you if there's a hundred out there.
There's the city behind me.
Yeah, so the mosquitoes in Canada and even maybe more so in the Yukon they've uh adapted to this seasonal thing where where they'll all pretty much die in the winter, so there's no no persistently mosquitoes alive. It's like you either reproduce while it's warm, which is like 4 months if you're lucky uh and the ones that don't make it, just die.
So the selective pressure on mosquitoes has been to become like this homing missile of I'm going to suck your blood.
Some of my friends I'm working with who who come from India were like they couldn't believe it. They're like these are not mosquitoes. Like those are mosquitoes because they're all making that like cloud formation that those birds do when you see them in the videos all kind of like synchronized and as the wind blows you see them all kind of equidistant and it's just like that is the most terrifying thing that I could see ever.
So obviously I wasn't having a good time while we were down there. We were only down there for like 10 minutes though, thank God. So yeah, I say bring on the the cold snap because that'll kill a lot of them. If we don't get a cold snap then they generally tend to like last all summer but if we get a cold good cold snap, it can kill a lot of them right off the bat. Okay, so 166 days left till we move to Vietnam. That should be let me practice this before I say it. Một trăm sáu mươi sáu ngày nữa.
Yeah, I always get it wrong. Hope that was right.
