The adult worm lives in the intestine of its host, normally rats but also sometimes dogs and humans. Hymenolepis diminuta passes through the required intermediate arthropod host as a juvenile. Only when the intermediate host is injested by the definitive host will H. diminuta mature. The intermediate arthropod host is normally a grain beetle, and injestion of the intermediate host into the definative host normally occurs in piles of grain, where both rats and beetles live.
