Biology
The Uthoians resemble human-sized bipedal insects with a chitinous exoskeleton, two anterior pairs of what appear to be vestigial limbs, four eyes, and a distinct, large, tapering head along with fully developed wings that allow them to fly over short distances. Each Uthoian appears to be little more than a drone with no distinctions between individuals, although there are witnessed instances of drones towering over humans and their own brethren by a significant margin. Their vocal communication mostly consists of insectoid chirps and trills, although they are capable of speaking in languages other species comprehend should the need arise.

they were a quick-breeding race, with two genders. a single female Uthoian could give birth to five hundred hatchlings. Because of the presence of a metal called Vorgi 77, Uthoians have abilities called Biotics, making them deadly soldiers.
