[Originally] by Wayne N. Mathis

Coelopids are commonly known as seaweed or kelp flies. The family contains less than 40 species worldwide, with about half occurring in the temperate areas of the Australasian Region. Elsewhere in the world the family is also found in temperate areas, with species occurring in the southern Afrotropical and Holarctic Regions. Several additional species from the Australasian Region await description.

There is considerable intraspecific variation in some species, especially in overall size, wing length, and setal characters. The plasticity found in many "traditional" characters has led to considerable splitting at the generic level.

Under normal conditions coelopids are found in the wrack zone of temperate seashores where larvae exploit stranded and rotting seaweed. Specimens are sometimes very abundant in this habitat. Coelopa frigida (Fabricius) has been reared in the laboratory and used for genetic studies.
