what is the evolutionary reason for the itch of mosquito bites?

298 viewsBiologyOther

Like, I can understand venomous insects and arachnoids using it for hunting (spiders) or defense (hornets), but mosquitoes make their own life harder by their bites being itchy, as it facilitates their ‘prey’ wanting to kill the mosquito.

We evolved the itch to detect the foreign substance. The mosquito just needs the protein to keep your blood from cloting for a bit. It doesn’t care if you itch or don’t.

It doesn’t take much heat to denature the protein that causes the itch and when its fresh it’s not very deep, so a hot spoon (or sometimes I heat up the metal on a lighter) can stop the itch and bump from every happening if you catch it right away.
