Update: A few days after this sighting the caterpillar had moved to my garage door, where it stayed for seven days (without eating), each day climbing a little further up the door. By day seven I thought it was about to pupate so collected it and took it inside. To my surprise, three months later it is still in its caterpillar form. I also collected a second specimen (sightings Metura elongatus (Saunders' case moth) on 14 Mar 2019 and Psychidae sp. (family) (Unidentified case moth or bagworm) on 23 Feb 2019 - in an earlier instar) hoping they may be male and female. Both are still in caterpillar form. Eagerly awaiting a transformation.
