Stem-borer: Larva boring in stem, pupation in early spring in the ground (Spencer, 1972b: 44).

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.

The larva is described by Dempewolf (2001: 99).

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:

Prunus       Spencer, 1990: 104
Prunus cerasifera Cherry Plum   Spencer, 1972b: 119

Hosts elsewhere: Currently unknown.

Time of year - larvae: Early spring.

Time of year - adults: Currently unknown.

Distribution in Great Britain and Ireland: Kent (East Malling) (Spencer, 1972b: 44).

Distribution elsewhere: Widespread in continental Europe including Germany (Spencer, 1990: 104; Dempewolf, 2001: 99), Corsica and French mainland (Fauna Europaea).
