Mosquito bites itch
because the glob of saliva
the mosquito sticks there to prevent bleeding
when it's done feeding
to the body
. My personal theory is that scratching
the location will bring more blood
to the area, which will make the nerves
more sensitive, which will heighten the itching sensation. The best thing to do is think about something other than the bite until it goes away.
Only female mosquitos drink blood. Insert joke here.
Mosquito bite is also a slang term for a small breast or nipple.
