Nepenthes trap on right is just forming. The lid has not separated yet from the pitcher. Trap at left is mostly open with details still forming, such as the curling lip which has started to roll down and outward. Once mature, lids do not move, and lip symmetry will be nearly perfect. Amazing to watch grow through ugly duckling stages.
