Lactran

The Lactrans were an insectoid species native to the planet Lactra VII. The Lactrans resembled 30 meter-long slugs, but were regarded as being highly intelligent, as well as possessing telepathic abilities which were beyond Vulcan abilities. In 2270, the USS Enterprise visited the planet on a mission to investigate the disappearence of the USS Ariel. Captain James T. Kirk and his crew soon discovered that the Lactrans had placed the Ariel crew into a type of zoo which house different types of animals.

While compiling a report of the planet Orisha and its native inhabitants in 2380, Commander Deanna Troi identified the dominant inhabitants as being a insectoid species similar to the Lactrans, the Xindi, and the Nasat.
