Representatives of the conspicuous and diverse family Syrphidae are found worldwide, and adults of many species are of considerable economic importance as pollinators. Due to their relatively large size, frequently colourful appearance and conspicuous habits, most syrphid genera are readily identifiable in the field with the help of proper identification tools. We have developed an interactive photographic key that is intuitive to use yet comprehensive, covering all genera of Syrphidae in the Nearctic Region. Every page is fully illustrated, with accompanying text designed to highlight important characters. The key provides the most current classification for the family and adds 15 genera and subgenera not previously recorded or recognized for the region. Several species in the genera Chrysotoxum Meigen 1803, Dasysyrphus Enderlein 1938, Leucozona Schiner 1860, Platycheirus Lepeletier & Serville 1828 and Volucella Geoffroy 1762 are resurrected from synonymy. Two new synonyms are proposed: Ferdinandea dives (Osten Sacken 1877) and F. nigripes (Osten Sacken 1877) are proposed as new synonyms of F. buccata (Loew 1863).
