Alexandre Louis Lefèbvre de Cérisy
Alexandre Louis Lefebvre de Cérisy was a French entomologist.
De Cérisy worked as clerk to a solicitor. It was Jean Baptiste Godart who introduced him to entomology.
Of all insect orders, he was principally interested in Lepidoptera. Basing his studies on the use of the wing veins for the classification of Hymenoptera, he proposed in 1842, a similar system of classification for butterflies. He traveled throughout Europe, sometimes accompanied by naturalists such as Achille Rémy Percheron in Provence and Gabriel Bibron in Sicily. He was at the founding meeting, February 29, 1832, of the Société entomologique de France
Species of Lepidoptera named in honor of Cérisy are: Allancastria cerisyi and Smerinthus cerisyi.
