This trapping mechanism is for the Trumpet pitcher only.
The lid is basically an advertisement in the pitcher plant. The bottom side of the pitcher plant is covered with nectar and microscopic downward pointing hair. When any insect comes to collect the nectar the ant gets a downward thrust from the microscopic hair and falls into the liquid. Without the lid the pitcher plant will not be able to catch insects.

A pitcher plant senses changes in air pressure when it's about to rain, and it closes a leaf over it's "pitcher" to act as a lid so that the rain will not diluet the mixture inside.
The pitcher plant closes its lid to trap insects as a means of protecting its digestive enzymes and maximizing nutrient absorption. This rapid closure helps prevent the insect from escaping, ensuring that the plant can digest its prey and absorb essential nutrients, particularly nitrogen, which is often scarce in its natural habitat. By efficiently trapping and digesting insects, the pitcher plant enhances its survival and growth in nutrient-poor environments.
The body of the pitcher plant is called the "pitcher," which is a specialized leaf that forms a tubular, fluid-filled structure. This adaptation allows the plant to trap and digest insects, providing essential nutrients. The upper part of the pitcher is often referred to as the "lid" or "operculum," which can open and close to facilitate the capture of prey.
Pitcher plants are carnivorous plants. They grow in bogs and poor soil, so they need insects to make up for the nutrients that they miss from the soil.
