Garc
From ROI Wiki
The Garc are a large Pill Bug like insectoid species common to the Angalorian empire. While the location and name of their homeworld is not known, they are seen from time to time in places all throughout the galaxy. But, most of the time, their species holds to a very strict policy of isolationism, only being seen when absolutely necessary. Otherwise, like real Pill Bugs, they prefer instead to hide in the shadows or in places where they can't be easily seen or found.
