Notes on the Life Cycle of Bunodera eucaliae Miller (Trematoda, Allocreadiidae) of the Stickleback, Eucalia inconstans

Bunodera eucaliae was described by Miller (1936, Canad .J. Res. D, 14: 11-14) in Quebec. It has since been reported from Wisconsin by Bangham (1944, Trans. Wis. Acad. Sci., Arts, and Letts. 36: 291-325) and Fischthal (1945, Trans. Wis. Acad. Sci., Arts, and Letts. 37: 157-220). In 1948 near Lamont, Iowa, the writer discovered a small spring pool which was two miles distant from the Maquoketa River. Since there was only the one species of fish present it furnished an excellent opportunity for making observations on the probable life cycle of this fish\u27s only digenetic trematode, B. eucaliae
