Illustrations with Butterfly Wings - Don't Let This Chance Flutter By

Many artists incorporate butterflies into any work they want to give an extra dose of cuteness to. With their vividly colored and patterned wings, it's not hard to see why. You'll even find works on pixiv with the tag #choukawaii, which is a play on words as "chou" can mean "butterfly" or "super" depending on the kanji used. 

As one would expect from the King of the Fae, Oberon (from Fate/Grand Order) seems to have a soft spot for butterflies. 

Have any of the illustrations below given you butterflies in your stomach?
