Can a butterfly feel pain, for example, if it breaks a wing?
Butterflies have a nervous system but it is different from people. Butterflies lack the special cells that allow people to know they are feeling pain. Butterflies will have a sensation that something is different, but they will not feel pain like a person experiences. An example is if you hold the leg of a butterfly, it will struggle. If you break the leg off, it will stop struggling and fly away. If the butterfly was feeling pain, it would react differently.
