The first instar makes a mine on the upperside of a leaf. Usually later instars feed externally on the leaves which they roll upwards so that the silvery underside of the leaves are seen. In some cases, it has been observed that the caterpillars keep mining throughout a much longer period of their life.
Pupation amongst leaf litter or in the ground near the base of the foodplant.
The species hibernates as an adult. Adults are rarely seen.
One generation a year: from July, hibernating, till April.
Monophagous on Carlina vulgaris.
Xerothermic limestone areas.
