Eggs of Hymenolepis diminuta are passed out in the feces of the infected definitive host (rodents, man) . The mature eggs are ingested by an intermediate host (various arthropod adults or larvae) , and oncospheres are released from the eggs and penetrate the intestinal wall of the host , which develop into cysticercoid larvae.
