Delia cardui (Meigen, 1826).


Leaf- and stem-mine: Mine always arising from the leaf base or ending in it, because the larva mines and changes leaves. Mine often broad, irregular corridor like, often touching the midrib. At first corridor often entirely without frass, later in the spring the mines are often less deep, containing thick, irregularly deposited frass lumps.

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: The records of Delia cardui on Lychnis and Silene are unsubtantiated (Mike Ackland, pers. comm.). Ackland in Chandler (1978) did not indicate whether his host records were British or Foreign and are therefore tentatively included under 'Hosts in Britain' and 'Hosts elsewhere'.

Lychnis coronaria is treated as Silene coronaria (Rose Campion) by Stace (2010).
