I came across a reference to a possible re-introduction of the Mazarine Blue in a document titled "The Unesco Strategy for Action on Climate Change"
http://unesdoc.unesco.org/images/0016/0 ... 62715e.pdf
At the bottom in small print it says:
Has anyone heard any more about this? Personally I can't see a problem with re-introducing a species that used to occur in Britain naturally.Researchers are using bioclimatic models for the Mazarine Blue butterfly, Polymommatus semiargus, to determine what locations within its historic British range will be suitable for its reintroduction.
