A comprehensive list of the insect prey of 47 species of Syrphidae from India and neighbouring countries is presented, including a total of 542 individual records. The introduction includes a detailed summary, with references, of different insect groups known to be preyed upon by syrphids from all over the world, this being the first time that such a summation has been attempted for the Syrphidae. Pertinent information on predacious syrphids, their role as biocontrol agents, and a short historical account of Indian work on their biology and ecology is provided. The syrphid-prey list details recorded information on the 47 species of syrphids for whom prey have been recorded. This includes the author's own rearings and other unpublished data from the CIBC Indian Station, which together total 46 new prey records. Incorrect prey data and doubtful predator identifications are indicated or corrected. The prey-syrphid index gives the syrphid species recorded as preying upon the 77 prey species listed. The list of references constitutes a bibliography of all papers citing prey information on Indian syrphids, as well as those providing data on different prey groups of world Syrphidae.
