Their midsections are conical in shape, being larger around the head and smaller around the legs, with hunched backs. Their bodies are a dull green color, darker in some places and lighter in others. The Gromflomites are insectoid creatures, sporting many features similar to common flies and praying mantises. The majority of Gromflomites depicted on the show happen to be soldiers, but they are otherwise not implied to be a wholly militaristic society, with civilian Gromflomites making some appearances. At least one Gromflomite, Krombopulos Michael, has taken on jobs that sometimes require action against the Federation, including the killing of Federation-aligned Gromflomite guards, suggesting that the species as a whole may not be loyal to the Federation.
Gromflomites are shown to comprise the entire upper echelon of the Galactic Federal government, as well as most of their military, the latter referred to as the Galactic Militia. The history of the species is largely unknown, but they appear to have established or otherwise obtained control of the Galactic Federation at some point.
