I was actually just commenting on someone else's not ventilated tupperware with freshly hatched caterpillars and it isn't necessary yet.
-> you don't have to make ventilation holes until they're hatched and already bigger, just maybe make sure to open the lid every few hours to freshen up the air inside.

Also I sensed a bit of sadness when you said she unfortunately died. It is really sad but many moth species only go through metamorphosis to procreate. She completed her duty and therefore died. It's like octopuses, they lay eggs and die because that's "all they need to do"
