After entry into humans, the plerocercoid larvae (spargana) migrate to different anatomic locations, where they cause space-occupying lesions as they develop into adults.

The infected Cyclops is then ingested by a small freshwater fish (second intermediate host) where the procercoid is released and penetrates the intestinal wall of the fish developing to a plerocercoid larva (sparganum) in the fish's muscles or viscera.
plerocercoid larvae of an unknown cestode species, and the nematode Hysterothylacium aduncum were observed too infrequently (<4% prevalence in all samples) to be considered useful as biological tags (see MacKenzie and Abaunza, 1998).
