Ok, I've searched and I've asked around and it seems that no one can answer a seemingly easy question.

So you're sitting there and you feel the old annoying pesky little ****** bite you so you give her a good slap while she still has her proboscis stuck in your flesh. You kill her and squash her into now an unresembled grey smear on your arm/leg whatever. Well my question is, what happens to the proboscis embedded in your flesh when you slapped her? When you're bitten there are the mandibles in your flesh, the hypodermic that's injecting you with saliva and the proboscis is in you. That's lots of miniscule bits of mozzie in you! Are the mouth pieces ripped off and are now in your arm? Are the bits pulled out with the body? What goes on?
