The Butterfly Dragons elements are Air, Lightning and Fire.
Breeding combination that worked for me
Firefly Dragon + Air Dragon
|This is what your Butterfly Dragon Egg will look like|
You can also try breeding:
Seaweed Dragon + Lightning Dragon
You're looking for a 12 hour incubation time.
|And I absolutely love how the baby dragon looks like a little caterpillar ;)|
If you've found another combination that worked for you, feel free to add it!
