They flap and create enough lift for takeoff, and can potentially be used for camouflage. That's the only shared characteristic though, because butterfly wings are part of the insect's exoskeleton, and bird wings are technically arms. They don't share anything in build or ancestry.

These organisms share a common ancestor with each other.
butterfly Wing shape
the wing of a viceroy butterfly is like a monarchs but the wing veins aren't straight
the wing of a bird. Both wings serve the same function of flight but are made of different materials and evolved separately in each species.
There are a few different similarities between the wing of a butterfly and the wing of a bat. Both are used to fly for example.
The wings of a glass wing butterfly are transparent, while the painted lady butterfly's wings are not transparent.
I search around and I came up with the Apollo butterfly, a white butterfly with two red spots on each lower wing. Click the link below for the link. You didn't give much information, so that was the best I could do.
A bird without wing
It can no longer fly and will eventually die of either starvation or being eaten by a bird or lizard.
