Pegomya interruptella (Zetterstedt, 1855)
[Diptera: Anthomyiidae]


Anthomyza interruptella Zetterstedt, 1855. Dipt. Scand. 12: 4742.
Pegomya interruptella Zetterstedt, 1855.


Leaf-miner: Not distinguishable from the mines of P. betae or P. hyoscyami.

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).

Comments: Ackland in Chandler (1978) did not indicate whether his host records were British or Foreign and are therefore included under 'Hosts in Britain' and 'Hosts elsewhere

Hosts in Great Britain and Ireland:

Solanaceae        
? Solanum       Ackland in Chandler, 1978: 228

Hosts elsewhere:
