When grain beetles (Tenebrio molitor) were fed eggs of Hymenolepis diminuta, many of the eggs passed intact through the beetles' intestines, and eggs were present in the beetles' feces for at least 48 hr after feeding. When uninfected T. molitor were fed beetle feces containing H. diminuta eggs, they became infected. Tenebrio molitor were fed on H. diminuta eggs and then placed in fresh bran for 48 hr. When uninfected T. molitor were placed in this bran, they became infected. Thus, feces from beetles that have ingested H. diminuta eggs serve as a source of eggs for other beetles, as well as a mechanism of egg dispersal.
