In Britain, butterflies are also on the wane. In the 19th century, they would flock in the wild in quantities sufficient to obscure your view. Now as populations dwindle , they're a rare treat.

I've see a lot of encouraging signs of rehabilitated wildlife, as I wander round the green corridors of Bristol, walking that dog . We don't see many butterflies.
