MONTIA. Blinks. [Portulacaceae]


Two species of Montia are recorded in Britain. These include the native Blinks (M. fontana) and the introduced Small-leaved Blinks (M. parvifolia).

Only one British miner is recorded on Montia.

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

insects (Diptera and non-Diptera) recorded on Montia


1 > Leaf-miner: The mine starts as a long, narrow, winding corridor running towards the midrib, widening to a blotch. Usually upper-surface, but in small leaves also full-depth parts may occur. The blotch has broad lobes; in their ends most frass is accumulated in the form of green patches or clouds. Sometimes several larvae share mine. Pupation usually in the soil, less often in the leaf (and then generally not in the mine itself but in a small separated mine, that may even be made in the petiole).
