Insect Armageddon?

The displacement of the jet-stream with the consequent loss of the British summer with heavy rains and strong winds has been reported to have lasting and extensive detrimental effects on butterfly (http://www.guardian.co.uk/environment/2012/jul/12/david-attenborough-butterfly-count) and bee populations (although declines in the latter have also been linked to parasites and pesticides). All this is bad news for crops requiring insect pollination. Although why Attenborough has to illustrate his plea by being pictured with exotic butterflies in a Butterfly House is beyond me!
