Then Fabre intervened in the wasps' process of catching prey, and only one of the species adjusted their behaviour in response to this unfamiliar interception. All of the wasp species he studied performed a certain pattern of behaviour when catching their prey, which Fabre called a fixed pattern. One specific example that helped him arrive at this conclusion is his study of various wasp species.

The following are some insect and animal behaviours that Fabre observed and labelled 'instinctive', for they do not involve reasoning:įabre believed instincts were 'fixed patterns', meaning these linked sets of behaviours do not change in response to novel environmental situations. While these instinctive behaviours appeared complex, the insects and animals did not adjust their behaviour despite it not helping them in that novel situation. He came to this conclusion after observing how insects and wild birds continued to repeat a certain behaviour in response to a novel situation. Insect and animal behaviour įabre concluded a significant difference between humans and animals is that animals cannot reason. Fabre considered an instinct to be a linked set of behaviours that an organism undergoes unconsciously in response to external conditions. Jean Henri Fabre (1823–1915) is said to be the first person to study small animals (that weren't birds) and insects, and he specifically specialized in the instincts of insects.
