Why are moths usually portrayed as poisonous in video games, when theyre not in reality?

I've never understood this. In Resident Evil Code Veronica there are poisonous moths. In Devil May Cry 2 there are poisonous moths. Elden Ring has an ash of war referencing poison moth. Pokemon has venomoth. Miitopia of all things has a poison moth. I could keep going on. I've never understood where the tradition came from. Can someone shed light on this?
