Why don't you feel a mosquito bite until after it begins to itch?

A mosquitoes has a very tiny probiscis that makes such a small wound in your skin that you usuallly don't feel it. The wound is also so small that blood would almost instantly clot and not flow, so the mosquitoe injects an anti-coagulant to keep blood flowing. It is the anti-coagulant that makes you itch.
