The first picture show the case that the caterpillar lives in as it feeds on eucalyptus leaves. Unlike most case moths it only has a few decorations when the case is small, but they drop off or are discarded and the ribs develop giving the distinctive and very strong case, which is constructed of very strong silk threads. The flightless female stays in the case and even lays her eggs in it, but the male eventually emerges from the case as a winged moth
