TUSSILAGO. Colt's-foot. [Asteraceae]
Colt's-foot (T. farfara) is the only species of Tussilago recorded in Britain.
Three dipterous miners, the agromyzid Phytomyza tussilaginis and the tephritids Acidia cognata and Trypeta zoe are recorded on Tussilago in Britain.
Elsewhere the agromyzids Liriomyza strigata, Liriomyza huidobrensis and Phytomyza tussilaginis, and the tephritids Acidia cognata, Stemonocera cornuta and Trypeta zoe are recorded mining Tussilago.
Three non-dipterous miners are recorded on Tussilago in Britain (see below).

Key for the identification of the known Diptera mines in Britain.
1>Blotch mine. Pupation external. Puparium yellow
Stemonocera cornuta (Scopoli) [Tephritidae].
-> An upper surface corridor mine, becoming strongly broadened and blotch-like. The mine can occupy a considerable part of a small leaf. Mines frequently merge, and then accommodate several larvae. Pupation external, in soil. Puparium yellow
Acidia cognata (Wiedemann) [Tephritidae].
->Corridor mine following the mid-rib, with lateral offshoots. Puparium yellow
Trypeta zoe Meigen [Tephritidae].
->A long linear greenish-white mine which can conspicuously widen at end, with frass in separate grains. Puparium black
Phytomyza tussilaginis Hendel [Agromyzidae].
