Counting bats and tallying bugs

This week, Stu looks at reports that insect populations are falling, and finds out that the threat may have been exaggerated. Meanwhile, Chris goes on a citizen science expedition and takes part in a flying-fox fly-out count, to find out how populations of these megabats are faring.
