Stem- and seed-feeder: Larvae feeding in seed-head and stem, pupating externally (Spencer, 1972b: 77).

Larva: The larvae of flies are leg-less maggots without a head capsule (see examples). They never have thoracic or abdominal legs. They do not have chewing mouthparts, although they do have a characteristic cephalo-pharyngeal skeleton (see examples), usually visible internally through the body wall.

Puparium: The puparia of flies are formed within the hardened last larval skin or puparium and as a result sheaths enclosing head appendages, wings and legs are not visible externally (see examples).

Hosts in Great Britain and Ireland:

Orobanche       Spencer, 1972b: 117

Hosts elsewhere:

Orobanche       Spencer, 1990: 215

Time of year - larvae: Currently unknown.

Time of year - adults: Currently unknown.

Distribution in Great Britain and Ireland: Local but probably Widespread in Britain including Hertfordshire (nr. Ivinghoe), Huntingdonshire (Leckford) (Spencer, 1972b: 77) and North Hampshire (NBN Atlas).

Distribution elsewhere: Widespread in continental Europe including European Turkey, French mainland, Germany, Hungary, Italian mainland, Malta, Sicily, Spanish mainland and The Netherlands (Fauna Europaea).

Also recorded in western Asia (Spencer, 1990: 215).
