I suggest these are larvae of Calyptra minuticornis (Erebidae-Calpinae-Calpini). They are feeding on snake vine (Stephania japonica) a known host plant, which grows commonly across the island.
Hi Jackie - I didn't find any description of the larvae at the link you provided, The description of the adult was very detailed in a technical sense but gave absolutely no indication of its odd appearance and mimicry. When I first saw the moth, up under the eaves, I really did think it was a bit of dead leaf caught in a spider web!
Hmmm. Looks like there could be quite a bit of variation across sub-species around the world and also with instar stage and development.
