Puparium: Details unknown.

Adult: The adult is illustrated in the Encyclopedia of Life.

Comments: The species has been recorded feeding on decaying vegetation, particularly giant hogweed, Heracleum mantegazzianum and Cirsium. Chandler (1978) did not indicate whether his host record was British or Foreign and is therefore included under 'Hosts in Britain' and 'Hosts elsewhere'.

Robbins (1991) recorded Scaptomyza pallida on Polygonatum. This is not correct (Willem Ellis, pers. comm.).
