Why are butterflies wings symmetrical?


My question to you is what kind of symmetry are you referring to? If I understand your question correctly, are you referring to the left wing being a mirror image of the right? If that is your question, then the answer is that if the wings were not symmetrical, the butterfly would have a difficult time flying, since the wing on one side would have different lift and drag characteristics than the wing on the other side. Hopefully I have not missed your point!
