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.
It’s like you failed to read the first 2/3 of my reply.
The fact that many people are able to notice and whack many mosquitoes when they bite shows that it isn’t only after 5 minutes that people notice, leaving room for an evolutionary improvement that would allow them to live longer and thus reproduce more
