Rare butterfly population increases by 9000% in Kent in 20 years

The population of a rare butterfly species has increased by more than 90 times in Kent over two decades, according to a conservation charity.

There were fewer than 50 Duke of Burgundy butterflies in 2005, but this rose to nearly 600 last year, Butterfly Conservation said.

Dr Dan Hore, director of nature recovery at Butterfly Conservation, said this rise is a positive sign for the local environment.
