Dryomyzidae is a small family of flies.
There are about twelve species in four genera (two genera known only as fossils) Dryomyzidae are mostly found in the Holarctic Region although some are found in the Southern Hemisphere. Very little is known of the habits of the adults or immatures but adults are found in moist, shady habits among low-growing vegetation, fungi, and excrement. Larvae have been reared from decaying organic matter including carrion, dung, and fungi.
