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. Hosts in Great Britain and Ireland:
