No one likes to see flies investigating their picnic and so they are often shooed away. But how do flies find food? And do they really eat picnic leavings and other trash? Time to call in the bug explorers! In this book, readers begin their explorer training by finding out about flies' body features, where they're found, what they eat, and what their life cycle is like. Up-close photographs showcase features unable to be seen by the naked eye and complement the accessible text.
