 Hosts generally are humanoid creatures that are between 5 feet 4 inches and 6 feet 2 inches.The most desirable of races for hosts are Humans, Drow, Elves, Githzerai, Githyanki , Grimlocks, Gnolls, Goblinoids, and Orcs.Upon being implanted (through the ear canal), the larva then grows and consumes the host's brain, absorbing the host's physical form entirely and becoming sapient itself, a physically mature (but mentally young) Illithid.
