Chris Packham and Martha Kearney reveal the mysteries of that iconic insect of the British countryside, the honeybee. Chris and Martha discover which of our tagged bees have survived over the mid summer week - a frenetic nectar and pollen gathering period - and if they have collected enough food at this critical time to see them through the winter. With the help of Prof Adam Hart they will also explore the Queen's remarkably deadly mating ritual and look at how bees can help us medically and how we can help them.
