Wer kann mir sagen, um welche Raupe/Schmetterling es sich hier handelt?

Ich bin auf das selbe Problem gestoßen aber hab nun eine Antwort:
Es geht um eine spezifische art von Käfer der sich auf diese Pflanze spezialisiert hat (da giftig)..
Er schneidet zuerst ein rundes Loch und verspeist erst danach das innere, um wenig Gift abzubekommen (so hab ich es verstanden)

Zitat von dort ( es geht auch um die Pflanze):
Giant Taro: Toxic Beauty
As one of the representative plants of Hainan's National Tropical Rainforest Park, the giant taro (Alocasia macrorrhizos) is known for its shiny green leaves up to as much as one by three meters. In urban environments, some people use artificially cultivated alocasia as houseplants.
Despite a sap that causes an itchy rash and the genuine risk that accidental ingestion may lead to heart palpitations (or even cardiac arrest), the roots of this highly toxic plant—whose fanciful Chinese names translate to things like “wolfsbane” and “sharp-toothed taro,”—have shown great promise in recent year for a variety of medical uses.
Aplosonyx, a small orangey-red beetle, loves to eat giant taro leaves. In order to avoid the toxins in the sap, this tiny beetle cuts a circle and then munches down.
Although the leaf-cutting aplosonyx's feeding habits damage the giant taro, they have a mutually beneficial relationship, which includes pollination of the plant and, at the same time, food and shelter for both mature insects and their immature offspring.

The beetle Aplosonyx nigriceps has developed a clever tactic to be able to eat the Alocasia macrorrhiza leaves and avoid the toxic alkalis that the plant secretes. It nibbles a 3cm circle on the leaves to cut off the toxin transmission before feasting inside the circle free of poison.
