Can you tell the age of a beetle by the number of spots on its back?

It is not possible to determine the age of a beetle by the number of spots on its back. The number of spots on a beetle's back is determined by its species and genetics, and has no correlation with age.

Age determination in insects can be challenging and typically involves examining their physical features such as body size, color, and the presence or absence of certain structures. In some cases, growth rings on the exoskeleton or the number of molts a beetle has undergone can be used as indicators of age.

However, these methods are not always reliable and may not provide an accurate estimate of the beetle's age. Environmental factors such as temperature, humidity, and availability of food can also affect a beetle's growth rate and development, making it difficult to accurately determine their age.
