I’m having a similar issue, although it appears not as severe as your case. I started a topic here if you want to check it out: What pests chew holes in leaves? - #3 by gardenbuddhist
Since posting about the issue I’ve set up sticky traps. It’s been about 36 hours since doing so, but the traps haven’t yet caught anything. But I also haven’t noticed any further damage to my plant. I’ll keep checking daily.
