SCORPIURUS. Caterpillar plant. [Fabaceae]


Two species of Scorpiurus are recorded in Britain. Both are introduced and include Caterpillar plant (S. muricatus).

Only one British miner is recorded on Scorpiurus.

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



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


1 > Leaf-miner: Corridor leaf-mine in leaves. An upper surface linear mine with frass in conspicuous greenish strips, largely alternating at each side of the channel (Spencer, 1976: 241).

Upper-surface, unbranched corridor, relatively broad from the start on, but only weakly widening subsequently. The fresh mine is bright green, but turns whitish, later brown, quickly. Frass in a wide green band in the centre of the corridor, with small black granules at either side. Pupation outside the mine.

Forms an upper surface mine, with the frass in a green strips .
