The biggest factor in the loss of habitat is in the last half-century major timber where several acreage's have been drained, cleared and planted in a pine culture. They're green plants that turn the sun's energy into food energy through photosynthesis, so that puts them on the bottom of the food chain. The major source of energy for Venus Flytrap, which is the sun, not the animals they trap. A Venus Flytrap going dormant usually show in growth, and the leaves may slowly turn black and die. The plant will come back in Spring.
Dormancy can help a plant to survive bad conditions.
In a Venus Flytrap it is because the bugs don't live in the winter and they don't have anything to eat. The trap will die however after it has eaten about 3 or 4 insects. Check back later for more information on the life cycle as we compile it.
