Over all length 3.5 - 4mm. Small flies with a grey thorax and a pale brown abdomen marked with darker stripes. The species are hard to separate and are normally titled Minettia fasciata agg. as there are several very similar species whose biology is not yet well understood.
Damp woodland and vegetation along ditch edges. The larvae feed in rotting vegetation, possibly on other micro-organisms.
