The N.Amer Sarracenia pitchers and flytraps I'm familiar with need a winter cooling for long-term survival. If kept warm year-round they usually die after ~2 yrs. Nepenthes pitchers (the hanging kind) are tropicals and dont need a winter chill-down. Good luck with the red-eye breeding! I've got a couple dozen blue-tailed newt larvae growing now (Cynops cyanurus).
