A very rare and local species in Belgium, with most observations in the southern part of the country.
Native
The larva of the first generation lives in the stems, and the second generation lives in the flower buds and on the seed heads.
Pupation takes place in the excavated stem parts.
The adults are active at dusk and night and come readily to light.
Two generations a year from May to July and again in August–September.
The main foodplant is Inula conyza, but the larvae have been observed on other Inula species and even on other Asteraceae.
