I used to get mosquito bites but I stopped getting them as an adult. I realized after a while that my skin stopped reacting to them even though the mosquitos were still biting me.

I recently managed to coax one into biting me to test my hypothesis. I felt it go into my skin and watched it suck for a bit, but it didn't get particularly engorged on it. No mark the next day. My son had a bitemark from a non-deliberate bite, though.

It seems to be a known phenomenon (though I have no idea why it happened to me): https://outdoors.stackexchange.com/questions/4310/is-it-poss...

I think for some of us they literally don’t even bite anymore. They certainly have preferences in blood type. I also have super visible veins as a relatively thin athletic person, yet they just seem to have no interest in what’s on the menu.

It’s quite a luxury as someone who spends lots of time on trails. But I also feel somehow offended. What’s so bad about MY blood?

I believe they all follow trails of your breath, which is why they can be reliably found above your bed when inside

So its likely about how that smells

Or other trails toward you, while they probably would enjoy your blood in actuality even if they think they’re detecting something related to how the meal would taste or its nutrition levels by proxy

Let me know what you all know!

Oh, that’s an interesting observation I’ve never realized until you pointed it out. I’ve always been the target of mosquitos more than anyone else I know, but it seems to get worse the fitter I am. Now that I’m a bit pudgy and out of shape, I haven’t had anywhere near as many bites.

But, to be fair for me being fit and being in the regions where mosquitos exist en masse is a related phenomenon. Out of shape me spends less time on trails than fit me.

They certainly have preferences in blood type.

How would they know your blood type before biting you?

It's possible you're getting bit but not seeing the symptoms afterwards
