They're in the kitchen. They're in the garden. They zoom into your room when the window is open. They can seem annoying BUT they're important. Flies.

On today's show I spoke with senior curator of Diptera (Flies) at London's Natural History Museum & author of The Secret Life of Flies, Dr Erica McAlister. From her favourite species of fly, to why they're important & to what actually makes a species, Erica covers it all (whilst out on her daily government authorised walk). It was wonderful to chat to someone with such knowledge & passion about this world of insects.
