Life cycles of two species of echinostomes Echinochasmus japonicus Tanabe, 1926 and E. beleocephalus (Linstow, 1873) have been studied. In Primorye region the first intermediate hosts E. japonicus are snails of genus Boreoelona, E. beleocephalus develops in Parafossarulus. Second intermediate hosts are freshwater fish and tadpole of frog Rana dubowskii. Encysted cercariae of E. beleocephalus also were found in tissue of first intermediate hosts. Experimental definitive host for both species were Gallus gallus dom. chickens.
