detail

mine

The mine begins with a long and narrow corridor, that, according to Hering (1957a) originates in the midrib or leaf base. This continues into a large, full depth blotch from which almost all frass is ejected. The larva can leave its mine, and restart elsewhere; min without initial corridor can occur therefore. Pupation outside the mine.

host plants

Asteraceae, monophagous

Inula conyzae, helenium.

References to Buphthalmum salicifolium and Pulicaria dysenterica are almost certainly, and to Inula britannica and Dittrichia viscosa probably, incorrect (zie Klimesch, 1956b).
