Are you asking why mosquitos are attracted to blood, or why there is blood in the world?
assistant
Just why are they attracted to it.
user
Do you mean, why are there mosquitos?
assistant
No. I was curious what it is in blood that mosquitos want.
user
What makes blood attractive to mosquitos is the sugar, which is a basic substance called glucose, that is necessary for the mosquitos' survival.  This is the same reason why many other living creatures are attracted to the sugar.
assistant
Thanks.
