LURONIUM. Floating Water-plantain. [Alismataceae]

One species of Luronium is recorded in Britain. Floating Water-plantain (L. natans). The BSBI provide a downloadable plant crib for Luronium, Baldella and Alisma.

No miners are recorded on Luronium in Britain.

Elsewhere one British non-Diptera miner, Bagous alismatis, is recorded on Luronium.

A key to the European miners recorded on Luronium is provided in Bladmineerders van Europa.

Key for the identification of the known mines of British
insects (Diptera and non-Diptera) recorded on Luronium

1 > Leaf-miner: The mine starts with a broad corridor. Later a broad blotch, not determined by heavy veins. The mine is full depth and very transparent. The colour in the end is reddish-brown, making mined plants very conspicuous, even from a distance. Frass irregular. Often several larvae in a mine.

On Alisma plantago-aquatica, but not yet on Luronium, in Britain plus Luronium natans and Sagittaria sagittifolia, elsewhere. Widespread in Britain and continental Europe. Also recorded in the Republic of Ireland.

Bagous alismatis (Marsham, 1802) [Coleoptera: Curculionidae].
