Melvyn Bragg and guests discuss how animals influence the behaviour of others of their species by secreting or excreting chemical substances.
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.
