Tussilago farfara, Belgium, prov. Luxembourg, Malempré; © Jean-Yves Baugnée

Petasites hybridus, Nieuwendam

same mine, frass pattern
mine
Upper-surface, quite long corridor with irregular sides, in the end about 4 mm wide. Frass, in discrete grains, alternating along the sides. Pupation outside the mine; exit slit in upper epidermis.
hostplants
Asterceae, narrowly oligophgous
Petasites albus, frigidus, hybridus, paradoxus; Tussilago farfara.
Hering (1957a) also mentions Adenostyles, but Griffiths (1972b) assumes that this is in error. However, both Huber (1969a) and Maček (1999a) again mention Adenostyles alliariae and glabra as hostplants.
phenology
Larvae in June-September (Hering, 1957a).

notes
It is surprising that this conspicuous and not at all rare mine has not been found by de Meijere. Perhaps the species has become more common recently.
