@donhe PS I'm assuming that casemoths, like other moth/butterfly larvae, eat and grow for a while before they pupate; I have appropriate glass caging facilities to accommodate that, and can provide leaves of suitable plants if I know what plants will work.
Wonderful suggestion @donhe! I will be prepared for the next discoveries. If, as with these, it is unclear what they might prefer to eat, are there any sure bets, say particular plant(s) that might have a generally universal appeal?
