LEUCANTHEMUM. Oxeye Daisy [Asteraceae]
Five species of Leucanthemum are recorded in Britain. These include the native Oxeye Daisy (L. vulgare). Six dipterous miners, the agromyzids Chromatomyia 'atricornis', Chromatomyia paraciliata, Chromatomyia syngenesiae, Liriomyza strigata, Phytomyza leucanthemi and the tephritid Trypeta zoe, are recorded on Leucanthemum in Britain. The agromyzids Liriomyza sativae and Liriomyza trifolii, polyphagous pest species of ornamental and vegetable crops occasionally intercepted at UK points of entry, are recorded on Leucanthemum. Liriomyza trifolii has been found under glass in England and Wales. All populations have been and continue to be eradicated. The agromyzid Melanagromyza eupatorii is recorded boring the stems of Leucanthemum in Britain and elsewhere.	Oxeye Daisy - Leucanthemum vulgare
Elsewhere the agromyzids Chromatomyia syngenesiae, Liriomyza ptarmica, Liriomyza sativae, Liriomyza strigata, Liriomyza trifolii and Phytomyza leucanthemi and the tephritids Trypeta artemisiae and Trypeta zoe are recorded mining Leucanthemum. Two non-dipterous miners are recorded on Leucanthemum in Britain (see below).

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

1> Corridor mine primarily following the mid-rib. 2. -> Corridor mine not primarily following the mid-rib. 3. 2> Corridor mine following the mid-rib, with lateral offshoots. Puparium yellow Mine of Trypeta zoe on Artemisia vulgaris. Image: Willem Ellis (Source: Nederlandse bladmineerders) Trypeta zoe Meigen [Tephritidae]. -> A distinctive mine primarily above mid-rib, with irregular short lateral offshoots into leaf blade. Pupation external.     Mines of Liriomyza strigata on Sonchus. Image: Crown copyright - courtesy of CSL Liriomyza strigata (Meigen) [Agromyzidae] 3> Mine irregularly linear, whitish, distinctly widening, most frequently on lower leaves. Pupation external; puparium black Mine of Phytomyza leucanthemi on Leucanthemum vulgare. Images: Willem Ellis (Source: Nederlandse bladmineerders) Phytomyza leucanthemi Hering [Agromyzidae]. -> Mine linear, whitish, both upper and lower surface. Pupation internal, at the end of the mine, with the anterior spiracles projecting through the epidermis. Mine of Chromatomyia atricornis on Sonchus olearaceus. Images: Willem Ellis (Source: Nederlandse bladmineerders) Chromatomyia 'atricornis' auctt. [Agromyzidae] Chromatomyia syngenesiae (Hardy) [Agromyzidae]. -> Mine linear, long, frequently doubling back, initially on the underside, later chiefly on upper surface; frass in discrete grains; forming a loose string initially, later more irregular. Pupation in the mine. Puparium white Chromatomyia paraciliata Godfray [Agromyzidae].
