From February 1993 through October 1994, 382 cotton mice (Peromyscus gossypinus) were live-trapped and examined for bot fly (Cuterebra fontinella fontinella) larvae. Thirty-nine (10%) of the mice were parasitized by a total of 44 bot fly larvae. All bots were situated in the inguinal or lower abdominal region of the mice. Monthly data strongly suggested that this bot is bivoltine at this latitude with distinct summer and winter population peaks. Prevalence of parasitism was highest in June 1994 when 56% of 16 mice examined were infested with a mean intensity of 1.3 bots. Adult flies were successfully reared from 10 bots that exited from mice; the time period (58-98 days, mean = 79.5) that these specimens spent in the soil as pupae further supports the contention that C. f. fontinella is bivoltine on St. Catherines Island.
从1993年2月到1994年10月，共捕获了382只棉鼠（棉鼠属），并对其进行检查以寻找肤蝇（肤蝇指名亚种）幼虫。其中39只（10%）棉鼠被总共44只肤蝇幼虫寄生。所有的肤蝇幼虫都位于棉鼠的腹股沟或下腹部区域。月度数据有力地表明，在这个纬度，这种肤蝇一年发生两代，有明显的夏季和冬季种群高峰。1994年6月寄生率最高，当时检查的16只棉鼠中有56%受到感染，平均感染强度为1.3只肤蝇幼虫。从10只从棉鼠体内钻出的肤蝇幼虫成功培育出了成虫；这些标本在土壤中作为蛹度过的时间（58 - 98天，平均 = 79.5天）进一步支持了肤蝇指名亚种在圣凯瑟琳斯岛一年发生两代的观点。
