Liriomyza tragopogonis de Meijere, 1928

mine

Green, later brownish corridor or more often an elongated blotch overlying the midrib. The mine has short, irregular side branches. Frass in irregular, dispersed grains. Pupation outside the mine.

hostplants

Asteraceae, monophagous

Tragopogon porrifolius, pratensis.

Buhr (1932) mentions Scorzonera angustifolia and lacinata as hostplants in Mecklenburg (NW Germany). This association is not repeated in the later literature, although Buhr’s description of the mine closely fits that of tragoponis (and decidedly not that of the mine of L. scorzonerae).

Hering (1957a) mentions L. pusio in relation with Scorzonera; this species has been confused for decades with tragopogonis.
