Leaf-miner: Mine
indistinguishable from P. betae or P. hyoscyami (Bladmineerders van Europa).
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.
Puparia: 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).
Comments:
Pegomya exilis and Pegomya
cunicularia were distinguished from Pegomya
betae and Pegomya hyoscyami by Michelsen (1980). Material of both [the former species] had previously
been assigned to those [two latter] species (Chandler, pers. comm.).
