Large Blue Butterfly Makes Return
The large blue butterfly has made an astonishing comeback following a huge re-introduction effort, scientists say.
The large blue butterfly was declared extinct in Britain in 1979, but in the 1980s large blues were imported from Sweden by conservationists.
It seems that now there are around 20,000 in the UK, in 30 colonies.
It just shows that when conservationists put their minds to it amazing things can be achieved.
