This classic book is intended for beekeepers and bee scientists to enable them to identify the plants on which honey bees are foraging. It was first published in 1995 to replace the pioneering 1952 book by Dorothy Hodges. It contains charts showing the colours of pollen loads collected by honey bees from 267 species or varieties of wild plants, garden plants and agricultural crops. The plant species all grow in Britain, but the book is useful much more widely, so it includes an explanation of the colour charts in three languages (English, French and German).In 1995, the book was awarded a Gold Medal at the XXXIVth International Apicultural Congress (Apimondia) held in Lausanne, Switzerland. The second revised edition was published in August 2006. The author is a Council Member of the International Bee Research Association.
