The butterfly is an origami animal that in general is quite simple, although to fold the wings you should pay close attention to your fold lines. Don't get frustrated. I am positive you will be able to create it! It is an animate object which will flap it's wings if you press on it's body. I will show you two versions of the same animal, so you can choose with one you like best!
Remember the classification:
Inertebrate (Does not have a backbone)
Oviparous (born from eggs)
Most are herbivorouse (eat plants)
