Hoverflies are a somewhat misunderstood creature in British gardens - although they are essential pollinators for our plants and totally harmless to humans, they are often mistaken for wasps and avoided as a result. But whilst their similarity to their stinging lookalikes can cause panic amongst humans, it's also a deliberate defence mechanism that helps to protect them from predators. This story aims to educate children about these important insects, whilst also demonstrating that you can't always judge a book by its cover.
