Can you tell the age of a butterfly by the size of its wings?

No, you cannot accurately determine the age of a butterfly solely by the size of its wings. While wingspan and wing size do play a role in butterfly identification, the size of a butterfly's wings are not a reliable indicator of its age. This is because wing size can vary significantly between species, and is also affected by environmental factors such as nutrition, temperature, and humidity. Additionally, some species of butterflies continue to grow throughout their entire lives, so their wingspan and size would not be useful in determining their age. Instead, the best way to determine a butterfly's age is by observing its behavior and life cycle, which includes the duration of each stage of its metamorphosis.
