The biology of the Pseudopomyzidae is very poorly known. The larvae of the only European species are believed to develop in rotting logs or under bark. There is only one European species, Pseudopomyza atrimana (Meigen, 1830), which occurs in woodland, and adults have been found to gathering over rotting logs or attracted to the freshly cut and sappy stumps or logs of deciduous trees.
