Platypezidae, or flat-footed flies, are found worldwide primarily in sylvan habitats and are comprised of about 250 species in some 14 genera. Immatures of extant forms are fungivores. Adult males swarm before mating using trees or bushes as swarm markers. Some are attracted to wood smoke. The family is found in the fossil record as long ago as the Jurassic and consists of 11 species in 9 genera.
In addition to the determined material listed below, the family has been recorded by Poinar (1992) from the Oligocene/Miocene amber of the Dominican Republic. Undetermined material from the Cretaceous has been recorded by McAlpine & Martin (1969) (Canada), and Whalley (1981) (Lebanon). The record of the family from the Upper Jurassic/Lower Cretaceous of Siberia (Zherichin, 1978) has been shown by Kovalev (1989b) to be a misidentification for the thaumaleid Mesothaumaleia fossilis Kovalev.
