We report observations on reproductive phenology, fecundity and sporocarp morphology fora population of the semiaquatic fern Marsilea mollis B.L. Rob. & Fernald in southern Arizona and document the parasitic relationships of 2 insects collected with the plants. The recently described weevil Notiodes sporocarpicus O'Brien (Coleoptera: Curculionidae) utilizes the fern's sporocarp as a brood chamber, only the second documented instance of this form of parasitism in the United States. The wasp Lyrcus maculatus (Gahan) (Hymenoptera: Pteromalidae) is parasitoid of, the weevil in this system.
