I am reading a book about bats. A serious book about bats which explains how they hold their young, how one wing wraps around another when they are cold; the males and females switch roles at random and the bats have to be a certain temperature to reproduce.

To hunt, the bat listens to the rhythm of its prey; it hears the moth’s flutter, the grasshopper’s song and to adapt the prey changes it’s music to confuse the hunter.

I understand this.

Mating occurs by listening, to the one who bears the beats closest to your own and this is how they find each other when there is nothing else. But how do they know the difference, of what to eat or what to love?

This I’m not sure I understand.
