A Complaint About Butterfly? Blasphemy!
(This is an extremely trivial and pedantic complaint)
As someone who has taken entomology and learned to identify insect species based on the venation patterns (lines on the wings), it irks me how variable the butterfly gene is. I can rationalize it being different between breeds, but the differences seen between most genders would definitely classify them as separate species, probably even separate families.
That is all.
