Odiniidae are a small group of flies (almost 60 described species in about 10 genera) found worldwide but predominantly in the Holarctic Region. Adults of extant species are occur in sylvan habits where they can be found resting on tree trunks near slime fluxes or fungi. Larvae are reported as parasitic on the larvae of wood infesting Diptera and can be found in the galleries of wood-boring beetles or cossid moths.
In addition to the only described fossil member of the family, the Baltic amber species listed below, the family is also known from undetermined material originating from the Oligocene/Miocene amber of the Dominican Republic (Poinar, 1992).
