A blueberry or not a blueberry?

This debate seems to come up every so often when North Americans hang around in Sweden long enough. Swedes call these small berries that grow in shrubs along the ground blueberries and this drives the North American visitors insane and they can't understand this concept at all. I will hereby clear the whole mater entirely so that there will never be any confusion again.

Blueberries (Vaccinium Cyanococcous) grow only in North America. What we have in Sweden and call Blåbär, which is often translated literally into English as Blueberry, is in fact properly called a Bilberry (Vaccinium Myrtillus). If the two species were put side by side it would be obvious that they are not the same and once a person has tasted them it will be even clearer.
