An immense space-dwelling organism of the Delta Quadrant which lures starships into its digestive chamber by telepathically showing their crews exactly what they most want to see.
The telepathic pitcher plant is the name given to a creature seen in the Voyager episode Bliss. It is some two thousand kilometres across, hundreds of thousands of years old, and feeds on ships and their crews. It reads the minds of approaching travellers and feeds them comforting illusions.
Voyager's crew are shown a wormhole leading to Earth, along with letters from home full of good news. Seven of Nine and Naomi Wildman, who feel no pull towards Earth, and the Doctor, who is immune, see through the deception, but cannot prevent the ship from flying into the creature's maw.
Inside they meet Qatai, a lone pilot who has hunted it for forty years since it consumed his family. Working with him, they make the organism expel both ships. Qatai then goes back to his pursuit.
