The European species are uniform in appearance, small (2.0-5.0 mm), grey dusted, plump flies with thickened legs, especially in males. Wing with a dark spot at junction of R1 and mostly with dark patches along transverse veins. The larvae have the anterior spiracles shifted dorsad, though not so conspicuously as in Agromyzidae Fallén, 1823 (Krivosheina 1981). The adults occur locally, mostly in primeval or natural-type forests, from lowlands to montane altitudes, whilst some prefer forest margins or alder and willow stands alongside rivers; Odinia boletina (Zetterstedt, 1848) is regularly found on bracket fungus Fomes fomentarius. The larvae live under the bark of deciduous and (rarely) coniferous trees, mostly in the galleries of wood-boring insects (Coleoptera, Diptera, Lepidoptera) with ambrosia fungi. Younger larvae are most probably saprophagous or mycetosaprophagous inquilines, but older ones are predators of puparia and sick larvae, and at least some are capable of cannibalism.

The Odiniidae is a small family comprising two subfamilies, currently with 59 described species. Only the nominate subfamily is represented in Europe, with fifteen species in two genera (Carles-Tolrá 2007 and one species not included  there – Odinia rossi MacGowan & Rotheray, 2004). Seven species have been recorded in the Czech Republic by Máca (1997). Since then, only a few faunistic records have been added. Since the ECV1 (Máca 2006), the species number remains unchanged in the Czech Republic and has increased by one in Slovakia; eight species are listed in the present checklist: eight in the Czech Republic (seven in Bohemia, seven in Moravia) and six in Slovakia.

Papp (1998) published an account of the Palaearctic species. A survey of basic data on this family, also including data from the Czech Republic, is recently under preparation by S. D. Gaimari and W. N. Mathis. However, there is no recent detailed monograph of this family dealing with the European species. A primarily faunistic paper on the species then known from the Czech Republic and Slovakia was published by Máca (1978).
