Stem-feeder
:
Larvae normally feed in stems but have been found in the inflorescence
(Spencer, 1972b: 68).
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:
179).
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).
Yellowish, elongate; posterior spiracles each with some 10 bulbs
(without central horn).
Comments:
Spencer (1990) accepts a
Napomyza species on Linum
as representing lateralis. However, more detailed studies
may show that this population represents a distinct species.
