Cover Characteristic: Butterflies

The Cover Characteristic meme is hosted at  Sugar and Snark.   Here are the guidelines:

Each week we will post a characteristic and choose 5 of our favorite covers with that characteristic. If you want to join in and share your 5 favorite covers with the weeks particular characteristic, then just make a post, grab the meme picture (or make your own) and leave your URL in Linky (so we can visit).
You don’t even need to participate, just stopping by and saying hi would be great! Don’t forget to stop by the other participants!
