Centaur (Factoring Humanity)

The Centaurs (so named because of their home system of Alpha Centauri, rather than any physical similarity to the Greek mythical beast) are a species of sapient insectoids which have contacted Earth by means of radio messages in the early 21st century. Their skin color ranges from black to silver, with eyes that can be green, purple or cyan. They have large iridescent wings which can be folded and unfolded at will.
