I’d assume if a snatcher pods a female. They will become a juvie and eventually an imago, as all humans do. But some female genes remain and they transform into hunters.
Exactly as I theorized but agreed,to me it seems to make the most sense.
Or every Snatched female becomes Hunter while the male becomes the other type of Swarm!? 
So she is the female version of me!?
I only play with male COG characters (mostly Clayton, JD, Vermelo)! ♂️♂️
