I assume the maturation of butterfly pupae is governed by temperature. So early butterflies emerge from pupae that have successfully overwintered in cool, safe places.
Is it possible to duplicate this with very late pupae that will not be resuot in successful butterflies because of low temperatures? Lke the late Autumn ones? Has anyone attempted this?
I assume the commercial butterfly breeders must have some tricks like this to keep their stocks high. Any hints?
