Here are models of three butterflies I have built. They exist in reality and are called Peacock Butterfly, Menelaus Blue Morpho and Cethosia Cyane.
These models are also uploaded as a project on LEGO Ideas, so if you like them it would be appreciated if you gave it your support!
As shown in the video below, the butterflies can also move their wings automatically if you have an antenna piece connected to them and then tap on their wings.
