Fabre, Jean Henri (1823–1915)
Jean Fabre was a French entomologist who used direct observations of insects and arachnids, especially bees, ants, beetles,
grasshoppers, and spiders, in their natural environments in his pioneering
researches into insect anatomy and behavior. He emphasized the importance
of the theory of inherited instincts in these animals. His most important
work was Souvenirs Entomologiques (1879–1907).
