Like similar flatworms, its lifecycle involves two hosts. The adults, found in the guts of birds, lay eggs which land on the ground in the bird's droppings. The unfortunate host to follow, a snail (<i>Succinea</i> or <i>Oxyloma</i>), then eats the eggs, which hatch in its digestive system into small cilliated larvae called miracidia.

You see, the snails, on their own, aren't always the most tempting food for birds. They tend to hide a lot and are hard to see. But, seeing as the parasite needs to get into a bird's gut to continue its lifecycle, it isn't going to sit quietly and wait to get eaten. The tubes themselves mimic worms or caterpillars in appearance and movement, making them a tempting target for the parasite's adult hosts. On top of the visual attraction, the tubes serve another purpose - they blind the snail.
