Science Fiction. Mutants live outside a dome, while all the non-mutants live inside the dome. Cover: purple/blue butterfly.

[Summer]

Hey y'all, I read an awesome book a long time ago... It was a science fiction book with a purple/blue butterfly on the cover, and it was about mutants that lived outside a dome, while all the non-mutants lived inside the dome. I've already googled it ad nauseum...any help?

- When is "a long time ago" ... what year?
- Children's/young adult fiction or adult fiction?

There is a GR list for butterflies on book covers:

The reason I mentioned Pure above is it has a blue butterfly on the cover. It mentions mutants ...

Summer, is this book for teens or adults?

Around what year did you read this book? A range of years is fine.

Who is the main character?

I copied a few book details to the topic header. Feel free to edit it.

Could it be “The Chrysalids”, by John Wyndham?
