http://m.guardian.co.uk/environment/2013/mar/27/pesticide-bees-scent-food-neocotinoid Just after my piece about how bees see and smell – their ‘plastic’ sense of shapes becoming scents – I was sent this story. So perhaps pesticides are changing the shapes of scents to them: my film noir PI cross-cutting image may be more apt than I realised. It is a sad thought, a hives workers stumbling around drunkenly, seeking what they have for millions (or more?) of years, but unable to sense its real shape.
