Diplostomum spathaceum which is widespread throughout Utah in desert, mountain valley, and high alpine lakes, causes a disease known as diplostomatosis or eye fluke disease. Snails (756) were examined and two species, Lymnaea stagnalis and L. palustris were positive for D. spathaceum. Examination of 838 fish, which included 19 species, revealed 10 species (Salmo trutta, Catostomus discobulus, Salmo clarki, Micropterus salmoides, Catostomus platyrhynchus, Salmo gairdneri, Gila atraria, Catostomus ardens, Salvelinus fontinalis, and Richardsonius balteatus) positive for metacercariae of D. spathaceum. The only avian hosts positive for adult Diplostomum were Larvus californicus and L. delawarensis.
双穴吸虫广泛分布于犹他州的沙漠、山谷和高山湖泊中，会引发一种名为双穴吸虫病或眼吸虫病的疾病。对756只蜗牛进行了检查，发现静水椎实螺和沼泽椎实螺这两个物种感染了双穴吸虫。对包括19个物种在内的838条鱼进行检查后发现，有10个物种（褐鳟、盘口牛胭脂鱼、克拉克大麻哈鱼、大口黑鲈、扁吻牛胭脂鱼、吉氏大麻哈鱼、阿特拉里亚骨尾鱼、热情骨尾鱼、溪红点鲑和巴氏虹鳉）感染了双穴吸虫的尾蚴。唯一感染双穴吸虫成虫呈阳性的鸟类宿主是加利福尼亚鸥和德拉瓦鸥。
