Etymology

Origin of butterfly

First recorded before 1000; Middle English boterflye, Old English buttorflēoge; equivalent to butter + fly 1


Explanation

A butterfly is a flying insect with a small body and large, often colorful wings. Some gardeners plant specific flowers that attract butterflies. Butterflies are closely related to moths, which also have wings that are large in proportion to their bodies and antennae. A butterfly is distinctive because of its relatively large size and lovely, patterned wings. After hatching, they start as caterpillars, and eventually build a chrysalis, inside of which they transform into — and emerge as — a butterfly. The origin of butterfly isn't certain, though it may come from some butterflies' pale yellow color.
