For terms see [[Morphology of Diptera]].

Small and mostly deeply pigmented flies. The head is round.The face is not carinate. There are always two pairs of vertical bristles.The postvertical bristles on the head are divergent. Vibrissae on head are present.The fronto-orbital bristles vary from two pairs to none.The antennae are short and decumbent, the third segment elongate oval (face strongly receding and the antennae variable in length in ''Amphipogon'').The palpi are well developed.The mesonotum is almost always finely pubescent and polished.The sternopleura are never pruinose. There is one or two pairs of dorsocentral bristles and four scutellar bristles.The legs of the male never toothed or "deformed" and the front femora usually have long but delicate bristles.The costa is interrupted near the subcosta, close to radial vein 1. Anal vein of wing arcuate (continues parallel to postalar margin). The discal cell is usually large, with the posterior crossvein usually long.
The abdomen is more or less polished and pubescent but lacks bristles and is broad, depressed, not constricted at the base genitalia of the male more or less hidden and asymmetrical. The female ovipositor is extensile. -->

Piophilidae are small flies, often dark in color and shiny. The wings are usually clear and unmarked, with the exception of the genera ''Mycetaulus'', ''Neottiophilum'', ''Pseudoseps'', and ''Thyreophora'', which have brown wing markings.<ref name="Mcalpine-piophilidae">{{cite journal | last1 = McAlpine | first1 = JF | year = 1977 | title = A revised classification of the Piophilidae, including 'Neottiophilidae' and 'Thyreophoridae' (Diptera: Schizophora) | journal = Memoirs of the Entomological Society of Canada | volume = 103 | pages = 1–66 | doi = 10.4039/entm109103fv }}</ref> Like all [[Tephritoidea|tephritoid]] flies, female piophilids have an extensible [[Ovipositor#In insects|ovipositor]].

The family differs from the similar looking family Sepsidae in several characters, particularly in having the costa broken at the end of the subcosta, the setulose mesonotum and the absence of a hair or fine bristle arising on the posterior edge of the posterior spiracle of the thorax.
