More About the Venus Flytrap
• Range Coastal plain of North and South Carolina; also reported from New Jersey and Florida.

• Discussion: When insects or spiders disturb any two of the six tactile bristles on the upper surface of the folded leaves of this fascinating plant, the hinged halves of the leaf snap shut, trapping the prey. A chemical secreted by the prey stimulates the flow of the plant's digestive enzymes (this does not take place if the plant is stimulated by an inert object such as a pencil tip). Following digestion of the prey, the nutrients are absorbed and the leaf is reset. This plant is classified as an endangered species by the states of North and South Carolina and is protected by state law in the former. All the known locales are within a 50-mile radius of Wilmington, North Carolina.
