# Charles Ferton

Louis Antoine François Charles Ferton (17 January 1856 – 30 April 1921) was a French artillery officer and entomologist who studied the behaviour of hymenoptera and contributed to ideas on insect instinct.

## Life and work

Ferton was born in Chierry, son of a namesake nurseryman and a founding member of the Château-Thierry agricultural and horticultural society who was married to Louise Victoire Appoline Bujot. Ferton was educated at the Louis-le-Grand high school and graduated from the École polytechnique in 1875. He graduated from Fontainebleau in 1877 and joined the army and was posted in Avignon (1882–86), Châtellerault (1886), Bourges (1887), Vincennes (1888), Algiers (1889–90), Angers (1891), Marseille (1892–94) and finally Bonifacio (1895-1921). It was in Avignon that he learned of the work of Jean-Henri Fabre (1823-1915) and got interested in entomology. He was posted in Algeria where he began to study the hymenoptera. In 1895 he moved to Bonifacio as commandant and lived there until his death, even refusing promotions. He was made Knight of the Legion of Honor in 1817. He examined the stinging behaviour of Sphex subfuscatus and identified errors in Fabre's observations. He examined nest site recognition and orientation of leaf-cutter bees. He was a great friend of the entomologist Jean Pérez (1833-1914) after whom he named Osmia perezi (now Hoplitis perezi) in 1895. Like Fabre he used anthropomorphic descriptions. He became a member of the Entomological Society of France in 1890. In 1910 he received the Jean Dollfus Prize. He also took an interest in geology and prehistory, making studies in Corsica.
Ferton was a very thin man and he was nicknamed Mangia grilli ("eats crickets"). He was known to go on walks and destroy traps set for birds with his cane.His funeral was held at the Sainte Marie Majeure church before burial in the Saint François cemetery. His collections of insects from Bonifacio are held in the MHN in Paris.
A street in Chierry is named after Ferton. Halictes fertoni described by Joseph Vachal in 1895 from a specimen collected from Algeria is now a synonym of Lasioglossum discum (Smith 1853).
