Laccoptera cicatricosa?

Observation - Laccoptera cicatricosa? - Southern Africa. Description: On a similar, more... rounded beetle here, Kotuku said (of L. ruginosa) If under 10mm in length it

On a similar, more... rounded beetle here, Kotuku said (of L. ruginosa) "If under 10mm in length it is only likely to be confused with Laccoptera cicatricosa but that species is distinctly parallel sided." https://www.ispotnature.org/communities/southern-africa/view/observation/693318/tortoise-beetle-2
This one's fairly parallel sided, and while I can't judge sizes, I'd say it was under 10mm.
A would-be Ophelia in the swimming pool, so no clue as to food plant.
