Insectes Diptères du Nord de la France

Based in Lille in northern France, Macquart was one of three brothers who all became naturalists in the early 1800's — one an ornithologist, one a botanist, and Justin an entomologist who specialized in Diptera (flies). As a contributor the Suites à Buffon and in his independent works, Macquart named thousands of new species of flies, and his publications are an important source for current research in the Department of Entomology at the National Museum of Natural History.
