Or is it that the victims pest warning system is currently winning the biological arms race, in which case how are mosquitoes able to successfully reproduce? Or is it that mosquitoes have evolved such that their spawning numbers offset the difficulty they have biting?
Biology is hard.
The itch doesn’t begin until well after the female mosquito gets her food and leaves, so what reproductive advantage does it give to that specific mosquito over the others to make the itch not happen at all? The answer is “none”.
When I start itching from a bite, I’ll go on a killing spree and the one that bit me is most likely to meet its demise. But maybe that’s just me
Animals don’t do this, and humans are not the only prey for mosquitos. Also humans live in enclosed spaces which are hard for mosquitos to escape, which is only a few thousands years old, and evolution usually takes more time.
That makes sense
