Stem-borer: Internal stem borer. Pupation in stem (Spencer, 1972b: 19).

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).

Posterior spiracles separated by own diameter, solidly chitinised, black, with 10-12 bulbs around a strong central horn (Spencer, 1972b: 18, fig. 24).

Hosts in Great Britain and Ireland:

Time of year - larvae: Currently unknown.

Time of year - adults: Currently unknown.

Distribution in Great Britain and Ireland: Southern England (Spencer, 1990: 163) including Surrey (Bookham) (Spencer, 1972b: 19).

Distribution elsewhere: Widespread in continental Europe including Belarus, Germany, Latvia and Lithuania (Fauna Europaea).
