CHELIDONIUM. Greater Celandine. [Papavaraceae]
Greater Celandine (C. majus) is the only species of Chelidonium recorded from Britain. It is a native species. Two dipterous miners, the agromyzid Chromatomyia horticola and the drosophilid Scaptomyza flava are recorded on Chelidonium in Britain. Elsewhere the drosophilid Scaptomyza flava is recorded mining Chelidonium. No non-dipterous miners are recorded on Chelidonium in Britain.	Greater Celandine - Chelidonium majus.

Key for the identification of the known Diptera mines in Britain.

1> Mine linear, whitish, both upper and lower surface. Pupation internal, at the end of the mine, with the anterior spiracles projecting through the epidermis. Puparium whitish Mine of Chromatomyia horticola on Papaver rhoeas. Image: Willem Ellis (Source: Nederlandse bladmineerders) Chromatomyia horticola (Goureau) [Agromyzidae]. -> Corridor-blotch mine, normally dorsal; usually whitish; in small leaves it lies characteristically in the centre of the leaf often touching the petiole; in larger leaves it lies to one side of the mid-rib. Frass deposited in green clumps near the leaf margin. Pupation usually external, sometimes in a separate pupation mine. Mine of Scaptomyza flava on Brassica rapa.
