From his youth, Dejean was fond of entomology , especially the studies of beetles . He put together an extraordinary collection, which at the time was the largest in Europe with 20,000 species. The collection also contained beetles collected during the Napoleonic campaigns, for example at Waterloo. Since he traded a lot, he had beetles from all over the world in his collection. In particular, he specialized in ground beetles (Carabidae). He described many North American species that Johann Friedrich Eschscholtz had collected. He made himself particularly useful through a systematic catalog and a system of beetles, the Spécies général des coléoptères (with Charles Nicolas Aubé (1802–1869), 6 volumes, Paris 1825).

Pierre François Marie Auguste Dejean died on March 18, 1845.

His collection is now scattered in various museums (such as Turin, London, Barcelona).
