Taculbain

From Tardis Wiki, the free Doctor Who reference

The Taculbain were the descendants of a species used by Project Mecrim for research into their hive mind. They were a moth-like species and were worshipped by the Rocarbies.

The Taculbain were dependent on their queen. Most hibernated while a few acted as guards. They grew a variety of plants. Some could cause physical changes in the Taculbain, making them into warriors or changing their gender or making some into queens. One plant could be used to drug humans. (PROSE: The Menagerie)
