@MHAdvent Does the Seeker confirm that? All I have read so far (haven't gotten around to playing) is that it's molted many times and matured further. Many insects/arthropods and reptiles continue to molt and mature throughout their lives as adults.

Xeno also came from a cocoon which only adults do and this new one is smaller and a completely different colour while the original sneak peak we saw of it was green/black with constilation wings.
