The eggs are laid on the underside of the leaf. The larvae hibernate in the case and pupate shortly after the winter.
They are on the wing from late April till mid-June.
The caterpillars feed on Ericaceae like Vaccinium vitis-idaea, Vaccinium myrtillus and Vaccinium uliginosum. Sometimes also on Andromeda polifolia, but this plant is very rare and local in Belgium.
