My machinima friend Celestial Elf made this documentary about the rapid decline of butterfly populations:
the butterfly's tale
Swarms of butterflys were once widespread across our countrysides, but now you will be lucky to see one or two...
The decline is due to Industrial agriculture, the loss of 97% England's natural grasslands and wildflower meadows, the increase of motorways and urban development plus climate change which brings new predators and diseases..
Butterflys are essential eco system pollinators benefiting both agriculture and medical science for its plant derived medecines, as well as being sensitive indicators of environmental change.
The last species extinct in Britain, the Large Blue (Maculinea Arion)(d.1979) was re-established in the 1980's by Professor Thomas, who stated "What is bad for butterflys is bad for all species -- including our own''.

Around the world the Large Copper of Ireland, Giant Swallowtail of Jamaica, Atewa of Ghana, American Silverspot and Apollo of the Alps have also become extinct.
In The USA the Monarch butterfly now faces drastic reductions following destruction of their milkweed seeding plant by biotech agricultural chemicals.
