This is the adult moth of the caterpillar in sighting 4705541. Unfortunately this emerged while we were away travelling, and was found dead and quite dried out. Thought I'd post it anyways. Wings are clear like those of Hyalarcta huebneri, it appears to be a male moth. It emerged through the 'back-door' of the case, taking it's cocoon with it a few cm away from case. Cocoon shown in pic 4, case at end stage in pic 5.
