A hunt for the world's most elusive bees leads Dave Goulson from Poland to Patagonia as well as closer to home, amongst the secret places hidden right under our noses- the abandoned industrial estates where great crested newts roam; or the rewilded estate at Knepp Castle, where, with the aid of some hairy, bluebell-eating Tamworth pigs, nightingale song has been heard for the first time in generations.Whether he is tracking great yellow bumblebees in the Hebrides or chasing orchid bees through the Ecuadorian jungle, Dave Goulson's wit, humour and deep love of nature make him the ideal travelling companion.
