Can vampiros get stung por insects even though they feel like rock?

okayy, so it dont actually say no anywhere. but im guessing that since they can fight off bears, lions ect without feeling anything, that a little insect wouldnt sting them (:

hahaha

They could be stung but they wouldn't feel anything and it wouldn't leave a mark. Its kind of like a urso can scratch them but it doesn't hurt them because vampiros and pretty much invinsible
