LATHYRUS. Peas & Vetchlings. [Fabaceae]
Thirty species of Lathyrus are recorded in Britain. These include the native species Grass Vetchling (L. nissolia), Sea Pea (L. japonicus), Bitter-vetch (L. linifolius), Marsh Pea (L. palustris), Meadow Vetchling (L. pratensis), Yellow Vetchling (L. aphaca) and Narrow-leaved Everlasting-pea (L. sylvestris) and the introduced Broad-leaved Everlasting-pea (L. latifolius) and Black Pea (L. niger). Marsh Pea (L. palustris) is protected in Northern Ireland under Schedule 8 of the Wildlife (Northern Ireland) Order, 1985. Six dipterous miners, the agromyzids Agromyza lathyri, Agromyza varicornis, Chromatomyia horticola, Liriomyza congesta, Liriomyza pisivora and Ophiomyia orbiculata, are recorded on Lathyrus in Britain.	Broad-leaved Everlasting-pea - Lathyrus latifolius.
The agromyzids Liriomyza huidobrensis, Liriomyza sativae and Liriomyza trifolii, polyphagous pest species of ornamental and vegetable crops occasionally intercepted at UK points of entry, are recorded on Lathyrus. Liriomyza huidobrensis and Liriomyza trifolii have been found under glass in England and Wales. All populations have been and continue to be eradicated. Elsewhere the agromyzids Agromyza lathyri, Agromyza varicornis, Liriomyza bryoniae, Liriomyza congesta, Liriomyza huidobrensis, Liriomyza sativae, Liromyza strigata, Liriomyza trifolii and Phytoliriomyza variegata are recorded mining Lathyrus. Three non-dipterous miners, are recorded on Lathyrus in Britain (see below). Elsewhere one additional British non-dipterous miner is recorded on Lathyrus (see below).

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

1> Stem or root mine. 2. ->Leaf mine. 3. 2> An external stem or root mine. Pupation in the stem, near or even below ground level. Puparium reddish-brown, anterior spiracles projecting through the epidermis. Ophiomyia orbiculata (Hendel) [Agromyzidae]. ->A long white mine mainly in the winged stem, frequently starting in leaf. Agromyza varicornis Strobl [Agromyzidae]. 3> Initially a lower-surface linear mine, which later develops into large whitish blotch which appears like a pale mottled area from above, due to variable depth of feeding through to upper surface. Less frequently feeding in upper surface or stem. Puparium reddish Agromyza lathyri Hendel [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. Puparium whitish Mine of Chromatomyia horticola on Papaver rhoeas. Image: Willem Ellis (Source: Nederlandse bladmineerders) Chromatomyia horticola (Goureau) [Agromyzidae]. ->An upper surface linear mine with frass in conspicuous greenish strips, largely alternating at each side of the channel. Puparium yellow Vicia sepium Lathyrus pratensis Mines of Liriomyza congesta. Images: Willem Ellis (Source: Nederlandse bladmineerders) Liriomyza congesta (Becker) [Agromyzidae]. ->A long linear mine, normally starting on lower surface, frass in black strips alternately at sides of mine. Mine of Liriomyza pisivora on Lathyrus sylvestris. Image: Willem Ellis (Source: Nederlandse bladmineerders) Liriomyza pisivora Hering [Agromyzidae].
