Where it comes from

From Middle English buterflie, butturflye, boterflye, from Old English buterflēoge, equivalent to butter + fly. Cognate with Dutch botervlieg, German Butterfliege (“butterfly”). The name may have originally been applied to butterflies of a yellowish color, or reflected a belief that butterflies ate milk and butter (compare German Molkendieb (“butterfly”, literally “whey-thief”) and Low German Botterlicker (“butterfly”, literally “butter-licker”)), or that they excreted a butter-like substance (compare Dutch boterschijte (“butterfly”, literally “butter-excretor”)). Compare also German Schmetterling from Schmetten (“cream”), German Low German Bottervögel (“butterfly”, literally “butter-fowl”). More at butter, fly.

An alternate theory suggests that the first element may have originally been Old English butor- (“beater”), a mutation of bēatan (“to beat”), but this would not explain the cognates in other languages or the other names formed with milk products.

Superseded non-native Middle English papilion (“butterfly”) borrowed from Old French papillon (“butterfly”).

Contrary to popularised belief, the form "butterfly" was not derived from an earlier flutterby.
