"Der Mensch ist was er isst" reads the philosophical words of a German proverb.... "Man is what he eats"
It came to my mind as I noticed that this plant growing in the dunes was a prime source of food for wasps. Hordes of them were munching away on the yellow stuff, and apart from an occational fly, the small stingy hymenopterans seemed to have the stuff entirely for themselves.
Could it be the reason for wasps being partly        coloured?
