The larva lives at the underside of the leaf in a long, laterally compressed and brown spatulate leaf case that is straight, tubular and bivalved. Depending on the leafs of the hostplant used to construct this case, the latter can be hairy or, just the opposite, almost bare. The mouth angle is reasonably variable but is usually around 45°. The case can reach a length of 10–12 mm

The eggs are deposited at the underside of a leaf and the larvae also feed at that side of the leafs in a long and brown case. Remarkable is that the larva of this species constructs, with every moult, a new case. The old, abandoned one is left behind mostly at the leaf margin where the new case was built.
The caterpillar hibernates in its case and is full-grown by the end of May or early June and pupates on a stalk of the hostplant.
