Pegomya dulcamarae Wood, 1913
[Diptera: Anthomyiidae]


Pegomyia dulcamarae Wood, 1913. Entomologist's mon. Mag. 49: 85
Pegomya dulcamarae Wood, 1913; Ackland, 1965. Entomologist's mon. Mag. 101: 21-24. [Redescription].


Leaf-mine: Similar to the mine of Pegomya hyoscyami, but differs in the presence of an unusually large puparium. Probably a better discrimination is the unusually large clutch size, which is on averge is eleven (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: Ackland in Chandler (1978) did not indicate whether his host record was British or Foreign and is therefore included under 'Hosts in Britain' and 'Hosts elsewhere

Hosts in Great Britain & Ireland:
