The sexually mature monoecious self-fertilises in the mammalian rumen, and release the eggs along with faeces. Eggs hatch in water into ciliated miracidia . The miracidia then enters the body of an intermediate host, which are snails belonging to the genera Bulinus , Planorbis , Physa Stagnicola and Pseudosuccinea .
