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.
I am sure I read somewhere that they defecate in the hole after they have drawn blood and that is what causes the irritation. That does not sound as if they are particularly worried about being regarded as annoying, in fact it feels like they see it as a bonus.
That sounds completely made up. Why would they do that?
I definitely had that as vaguely factual, I thought heavy from blood they lightened the load before flying off and the hole was a too tempting target plus they enjoyed the symbolism. I asked ChatGPT and it said it was made up and was quite sneering about it so I suppose that is that.
