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 and Ireland:

Solanaceae        
Solanum dulcamara Bittersweet / Woody Nightshade British Wild Flowers by John Somerville et al. Ackland, 1965: 21-24

Time of year - mines: Currently unknown.

Time of year - adults: Currently unknown.

Distribution in Great Britain and Ireland: Warwickshire (Robbins, 1991: 98); Cambridgeshire, Herefordshire and \oxgordshire (NBN Atlas).

Distribution elsewhere: Recorded from Spanish mainland. Doubtfully recorded from Germany, Poland and Sweden (Michelsen in Fauna Europaea).
