ID by Michael Crisp: "It is Bonamia fruticosa but that name is not in your taxonomic tree. See Austrobaileya 9: 293 (2014)."
This record was uploaded as an accompanying record of the host plant of the leaf beetle shown in the preview image.
Bowerbird.org.au record being moved to iNaturalist because the former website is shutting down.
These tortoise beetles are eating an introduced pest vine called Turbina corymbosa. The vine as been around since at least the early 1990's and this is the first time I have seen insects significantly damaging it.
Feeding on the same plants as adults I have previously uploaded observations for. They live and feed in leaf blisters in the leaves and look just like the N. dorsalis larvae shown in Monteith et al. (2021), and no other Notosacantha is recorded in the area.
N. monilicornis based on range and 'It differs from N. dorsalis in having lower
elytral tubercles and only one pair of radial bars extending to margin of elytra.' - Monteith et al (2021) Australian Entomologist 48 (4): 329–354
