Did butterflies used to be called flutterbys?

It is not the original name for a butterfly. They were called butorflēoge, buttorflēoge, or buterflēoge in Old English, which evolved to buterflie, butturflye, or boterflye in Middle English, and finally butterfly in modern English. In German, there is a similar association with dairy products throughout the history of the Word's evolution. There is no evidence that the Word "flutterby" was ever used as the term for "butterfly" in any early English writings.
