Fasciola hepatica (liver fluke) infects its intermediate host and primary host at the following larval stages respectively
redia and miracidium
cercaria and redia
cercaria and metacercaria
miracidium and metacercaria

miracidium and metacercaria
In the life cycle of Fasciola, stages when it infects intermediate host is miracidium and primary host is metacercaria.
Miracidium- sporocyst, redia cercaria- metacercaria are the different larval stages according to development sequence.
Miracidium and cercaria larva are free swimming form in water while redia and sporocyst are formed in snail.
