A scarce migrant in Belgium, but more and more observations have been made since the first specimen in 2014 in AN.
The first larvae were found in 2021, so the species appears to be establishing itself here and the population is replenished annually by migrants.
Naturalised
A very rare migrant, having been noticed in Belgium for the very first time in 2014. In 2018 more than 50 individuals were already known from Belgium.
The adults can be seen from early May towards late October in generally two generations a year.
The larva feeds on Cirsium and Carduus.
The species inhabit open dry grassland.
