The Kollel replies:
I would say that it would be treated exactly like a caterpillar, based on the Rambam in Hilchos Ma'achalos Asuros 2:21. He says there that a whole bug that is decomposing and its form has changed is still considered a Biryah. Therefore the worm inside the cocoon, even though it is metamorphosing would still be considered a Biryah because it is indeed a whole creature.

This is not a Psak Halachah
