語源
英語の原文（Wiktionary）
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”)).
