Caterpillar
Abdomen whitish with a light brown head, the nape and anal shield are the same color as the body or grey-brown, the nape shield has dark spots on the side and back.
Bionomics
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 in a very dense cocoon 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).
Flight periods
The adults are on the wing from late April till July.
