I think that the blue armor is in fact the female version of the white armor because one, both the male and female Kecha-Wacha armors are shown, two, because the hunter wearing it appears to be female and three, it also seems to be insect-based, because of those wing-like blades on the arms. The 2 armors having different colors might be either because the Neopteron has a blue and white color scheme, or you always have to fight a white drone and a blue queen at the same time, similar to the Orugarons in Frontier.
