Bionomics

The monophagous larva lives in a mine on Inula conyzae. The first mine starts with a long and narrow corridor and later becoming a blotch with little of no frass visible. The larva can leave its mine and start another one and that explanes why there are mines without corridor.
Pupation outside the mine in a spindle-shaped reticulate cocoon, often at the underside of a leaf close to the midrib.
