Melvyn Bragg and guests discuss how members of the same species send each other invisible chemical signals to influence the way they behave. Pheromones are used by species across the animal kingdom in a variety of ways, such as laying trails to be followed, to raise the alarm, to scatter from predators, to signal dominance and to enhance attractiveness and, in honey bees, even direct development into queen or worker.
The image above is of male and female ladybirds that have clustered together in response to pheromones.

- Darcin! Ha ha ha.
- I hadn’t known until this episode that pheromones are defined by function, and not by chemical structure; and that everything can be a pheromone.
- The exception to the rule – predators or competitors eavesdropping on prey pheromones to see what was going on was amazing.
- The distinction between the two types of nasal systems / senses of smell is well worth reading further upon.
