Sphinx pinastri - Teneral pupa gaining colour
Found the caterpillar below in prepupa state (clearly ready to become a pupa) unprotected on the ground under a pine tree:
Decided to take it home and give it shelter until next spring. Upon arriving at home it had already moulted to a fresh pupa, probably an hour or so earlier, so I documented the rest of the process of the colour turning brown from 18:00h to 14:00h the next day.
