How is it that a tree branch can scratch the skin but a simple mosquito can break through it?

By Skylar

Have you ever come to ponder how a delicate mosquito can break through the skin but a tree branch only scratches it? First of all the mosquito’s body is built to puncture skin whereas the tree branch isn’t.   The mosquito’s small body and exoskeleton make the proboscis small enough and hard enough to pass right through the skin. The tree branches function isn’t to puncture the skin, so it scratches it. This is how a small delicate mosquito can break through the skin but a tree branch only scratches it.
