Just that - are there any and what is their role? I know there are insects and whale species who go through menopause and have roles such as guarding the colony, helping younger females and showing where food is, but are there species who do not mate or do not reproduce in all cases? Was thinking about it as I approach menopause as a childless woman (and I’m not going to justify being on Mumsnet!) and Google came up with no answer.
