Why is a butterfly so called?


Why is a butterfly called a butterfly, when it's nothing to do with butter and it's not a fly.

Answer: The first butterfly that comes out of hibernation in the spring is usually the male brimstone butterfly and it's bright yellow, like butter. We believe the name was given to all species of butterfly as the first one that came out was yellow.
