Coevolution of a venus flytrap

The coevolution of a venus flytrap is that it captures insects by having chemical mix nectar that able to attracts the insects and once the insect hit the trigger, that is inside of the plant, the venus flytrap will capture the insect then it will eat it. The Dionaea muscipula is related to the Aldrovanda vesiculosa  which is known as the waterwheel plant. The reason why those two plants are related is because both of the plants are carnivorous plants. Also the venus flytrap and the waterwheel plant are being threatened and endangered species.
