Farscape (1999)

S1E2 Exodus from Genesis

Moya becomes overrun by insects that have entered to reproduce. In a bid to accelerate their breeding, they raise the ship's temperature, resulting in Aeryn suffering from heat delirium due to her cold-blooded nature. To make matters worse, the bugs exhibit the ability to mimic the crew, creating even more chaos. Just when things couldn't get any more complicated, a Peacekeeper ship arrives on the scene.
