The presence of this very rare and local species in Belgium seems to be confined to the province of NA.
The larva feeds on the flower buds and flowers of the food plant. Later on it also accepts the unripe seeds.
Pupation on the food plant. The pupal stage lasts only ca. 10 days.
Two difficult to separate generations a year: from April to September.
Xerotherm slopes, mainly on limestone, where the foodplants grow.
