Chyliza extenuata Rossi, 1790
[Diptera: Psilidae]

Chyliza extenuata Rossi, 1790
Chyliza fuscipennis (Robineau-Desvoidy, 1830)
Musca extenuata Rossi, 1790
Chyliza atriseta Meigen, 1826
Dasyna fuscipennis Robineau-Desvoidy, 1830

Underground stem feeder: Chyliza extenuata is said to live in the swollen underground stem of Orobanche rapum-genistae Thuill., a perennial root parasite of leguminous shrubs, especially Ulex europaeus >and Cytisus scoparius, but also known to occur occasionally on Genista tinctoria> in Britain (Collin, 1944. Ent. mon. Mag. 80: 214-224.). It is not known whether it mines or not.

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:

Orobanchaceae        
Orobanche rapum-genistae     Collin, 1944

Hosts elsewhere: Currently unknown.

Time of year - mines: Currently unknown.
