I may be asking something that's already been asked (my apologies), but I've searched, and found nothing, so.......
What is the life expectancy of butterflies? Mine keep, ummmm, expiring and leaving behind bottles of milk. I massage them, I sing to them, there's a milker in my yard to keep them from 'sploding...is there something I'm missing or perhaps not doing? Or, is it simply that they have a finite time here in Ur before they leave for...well, wherever it is butterflies go when they, uh, die?
