New research suggests surprisingly few bee species are responsible for pollinating the world’s crops. Globally, a mere 2% of wild bees pollinate 80% of bee-pollinated crops. Monetarily, that equates to $3,000/hectare, or billions of dollars annually, a figure roughly equal to the value of honey bees.
A rare parasitic flower from South Africa puts out an entrancing smell to get local mammals to pollinate it. For the first time, these scents have been described, and we're starting to understand just why flowers smell so good.
