A widespread but rare species throughout Belgium.
The larva feeds when young in the roots, later on, and after hibernation, in the flower-stem. It pupates amongst the roots of the foodplant. The moths are active in afternoon sunshine until dusk and later occasionally come to light.
The adults have been observed from mid May till the end of July.
The larva feeds on Tussilago farfara.
