Pheromone glands are not visible ever. What is depicted here is a female "calling" for a mate. She requires fertilization, so this species assumes a posture, the terminal end opens up and exposes the gential vestibulum. Pheromones are produced internally but are so volitile that they exit the body through exhaling breath and by the opening of the vestibulum and spread rapidly through the atmosphere, generally up to a meter or two from the female.
