Genital structures in silk moths are very important for copulation and transferring
the gametes. Male genitalia is called the herpes and the female genitalia is
called the labius. Herpes is present at the terminal part of the abdomen of the
male, and has 2 strong hooks to hold the female labius during copulation.
Labius are present at the terminal part of the body which are fleshy with
sensory hairs, which help in copulation and transferring the gametes.
