The pink glasswing butterfly, Cithaerias pireta, affectionately known as the blushing phantom, may be one of the loveliest butterflies around. And one of exquisite contradiction: Part disappearing, part "here I am!" The species was discovered in the Amazon in the late 18th century and owes its magic to the absence of scales on the wings, except for a bold rush of pink on the bottom. Thank you to Andreas Kay for photographing this beauty in Ecuador.
