"Phil Lester's first book, The Vulgar Wasp, was about one of the world's most hated insects. His second is about just the opposite - the honey bee, arguably one of our best-loved six-legged creatures. People have revered honey bees for centuries. Today we celebrate them with toys, postage stamps and campaigns to raise awareness; we dress up in large bee suits to protest the use of pesticides; we've even sent bees into space and watched as they adjusted to microgravity. Bees are one of the world's most efficient pollinators. Their work is vital to the success of many food crops, and hence to the world's economy. So we need to take seriously any threats to their health - including parasites, pathogens, predators and pesticides - and, guided by evidence at every turn, find a way to minimise harm and keep bees thriving. As Healthy Bee, Sick Bee shows, this is no small task. In this book, entomologist Phil Lester explores the wonderfully complex and sometimes brutally efficient life history of honey bees, and the problems they face in New Zealand and around the globe. What causes a beehive to collapse? Are pesticides as big a problem as they appear? What can we do to improve the health of our honey bees? With intelligence, insight and entomologist jokes, Healthy Bee, Sick Bee tells the story of this much-loved little insect and offers new ways of thinking about how to ensure they will stick around in the future."--Publisher's description.

This seems a strange thing to say, with protestors worldwide demanding we "Save the Bees". After all, if all the bees died, wouldn't humanity shortly follow? (No, we wouldn't, but tomatoes and almonds would be a lot more expensive. Honeybees and bumblebees are needed for some crops, but in New Zealand about half our pollination is done by moths, flies, and native bees.)
There was no honey in Aotearoa until the first hives arrived in 1839. Since then the honeybee (/Apis mellifera/), like other European imports, has multiplied enormously. Bees are by far our most numerous livestock. There are now nearly a million hives in New Zealand, each holds around 40,000 bees in summer, and those 40 billion bees outnumber all the cows, sheep, pigs, people, dogs, cats, and every other introduced mammal put together. Plus the chickens. Forty billion honeybees is a lot: there are only 100 billion in the entire USA. Our national bee herd has grown 200% since 2008.
Why do we have so many bees? We got by just fine for years with far fewer, and the two main things that bees make – honey and wax – are these days almost useless. Sometimes it seems as if jars of honey exist only to be gifted, like the giant stone coins of Yap. Honey does have some medicinal properties, especially if made from mānuka nectar, but honey is very much like Savlon: it only works when smeared on skin bacteria and not – this, really, is the critical point – if you eat it.
