You can tell the age of a ladybird by counting the spots on his back.

The statement is false because one cannot accurately determine the age of a ladybird (also known as a ladybug) by counting the spots on its back. The number of spots on a ladybird's back is not an indication of its age. The spots on a ladybird's exoskeleton primarily serve as a defense mechanism and can differ in number and pattern between different species. Age determination in ladybirds generally depends on factors such as their size, development stage, and lifecycle duration. Counting spots on their back is not a reliable method for determining their age.
