A very rare and local species in the south of Belgium. Not seen for a very long time. Actual presence in Belgium uncertain.
Larvae can be found in June and July within the seed pods of the host plant. They feed on the seeds. When no seed pods are available, the larvae can feed on spun shoots. Pupation amongst debris on the ground. Empty seed pods are recognizable by a small round hole. Infected seed pods can be found by holding them against sun light and look for feeding signs. In the seed pods of Colutea arborescens other Lepidoptera larvae can be found as those of Lampides boeticus and Iolana iolas (not in Belgium).
The larvae live in the seed pods of Colutea arborescens.
