Abstract
The life cycle of this fluke was established in the laboratory and all stages described. The natural vertebrate host is unknown. Chicks and canaries were experimental hosts. Larval stages were present naturally in caddis-fly larvae and the snail, Lymnaea palustris. The adult worms live in the small intestine: eggs require ingestion by the snail in which 2 generations of sporocysts develop before the production of mature cercariae at 22 to 35 days. Metacercariae develop in larvae and adults of Limnephilus and mature into adult worms about 11 days after penetration. Anatomical comparisons are made with other spp. in the genus, together with comments on morphological diagnosis of the genus Plagiorchis.
