But what the hell, it doesn't do much harm to give it a try does it? If
you've got the time and effort give it a go. If it doesn't work then you
can revert to why. Neil would probably be horrified to know that I have a
healthy population of Black Hairstreak (S. pruni) thriving in the woods
behind my house in Southern Hampshire, UK. I just let them go and that was
that! OK this doesn't work with most species, but often habitats change and
become suitable again if only the butterfly could reach it.
