The Lahit were a non-humanoid arboreal species native to Flyspeck (1212 Muscae IV), coexisting on the planet with the Ornae. In the late 2260s, approx. 20 million Lahit lived on Flyspeck. They formed hive economies and moved across the surface as colonies. Lahit were also welcome to live among the Ornae in their makeshift settlements. Following first contact, a treaty was signed with the Federation. The Lahit and Ornae intended to join the Federation. (TOS novel: Doctor's Orders) They could also exist as individuals. By the late 24th century at least one Lahit served in Starfleet. (ST - The Fall novel: The Poisoned Chalice)
