Gall midges, though possibly the largest family of flies, are poorly known. Interest is growing, however, as additional species are found to be pests, pollinators, or biological control agents. GagnT (research entomologist, US Dept. of Agriculture), author of PlantFeeding Gall Midges of North America (1989), summarizes the present knowledge of gall midges in the Neotropical region, an area that encompasses southern Florida, the West Indies, and the continental Americas south of the Tropic of Cancer.
