The T'lessian dragonfly was a species of large, omnivorous insect native to the Sa'ari homeworld of T'lessia. Due to the planet's lighter-than-standard gravity and oxygen-rich atmosphere, they could grow to be quite large, with wingspans in excess of one and a half meters and bodies approximately one third that length. Though generally harmless, several dragonflies working in concert could bring down a plek'kak or seriously menace a Human.
