Chris R. provides a very nice explanation, making the same point that Neil
was originally making I believe.  I do appreciate the info on the
difficulties that have been shown in the UK.  While I agree that nothing can
really replace the natural habitat, what do we do while the last remaining
habitat is being drawn and quartered - nothing?  Attempting to stop
development is noble, but should we stop there?  Why would we not at least
ATTEMPT to propagate foodplant to new (or old, restored) locations?

I have a friend that has developed a successful technique for propagating a
genera of exotic plants that botanists insisted were impossible to grow
outside of natural habitats.  In his case, it required over 30 years of
persistence and a whole lot of gray matter.

My only point is that someone should be trying it.  But then, I'm sure as
the heck not doing it.
