We are rearing Peacock butterfly caterpillars indoors. One morning a caterpillar was dead, seemingly only its outer skin left. Beside it was a perfect egg shaped case, translucent and milky bluey white. The case is maybe 5mm long and there is a living creature inside which you can see moving (to right in picture). There was also another object (left in picture) - brown, dropping shaped, not moving, not translucent.
