What are the external features that distinguish a male from a female?

Insects, like many living organisms, have males and females. And for some, the external differences between the opposite sexes are clearly distinguished. The size of the body, mustache, wings, color and other signs are characteristic of gender differences. Females of an insect praying mantis are larger than males and only males fly in mantises, and females in the abdomen carry future offspring. And in some cases, the external differences between the sexes are insignificant, this is often found, for example, in butterflies and the sex of an insect can be seen only when studying their sexual structure.
