Well, technically, there have been nuisance complaints about people keeping bird feeders that attract huge numbers of pigeons and other birds, leading to a bit of, shall we say, environmental downturn in the immedate neighbourhood. It would be reasonable to complain about someone attracting 1,000 starlings that roosted in your yard after feasting at the neighbours.
But butterflies? The mind boggles.
EvilTwik imagines putting a dead one on her walk, then running after her screaming, "You KILLED my butterfly! I'll have the law on you!"
