Drak

The Drak is an alien species of insect which lives in the cold space, but in order to reproduce they need warmth. In the Farscape episode "Exodus from Genesis," the Drak queen Monarch uses Moya as its warm nest. While on Moya, the Draks collect DNA samples from the crew, in order to produce replicants of the crew which the Monarch can command to defend the nest from any threats.
