Two generations of sporocysts are produced. The cercariae develop and remain in the daughter sporocysts. Masses of sporocysts, covered in mucus, are expelled form the snail's respiratory pore and deposited on vegetation. These masses are eaten by grasshoppers, or some other second intermediate host. When the metacercariae in the grasshopper are eaten by the definitive host, the worm excysts in the gut and migrates to the pancreatic duct where it matures to the adult stage.
Eggs pass down the pancreatic duct, make their way to the intestine, and exit in the feces.
Adult worm surgically removed from bile duct.
