Lymnaea cailliaudi prefer clear, slow-running water with low salinity and abundant vegetation.
The snail population is low in the summer months due to high temperatures, and increases gradually to reach its maximum in spring when the temperature is mild and vegetation flourishes.
Lymnaea cailliaudi has been found to be an intermediate host of both Fasciola hepatica and Fasciola gigantica. Overall, rates of snail infection vary between 10% and 40%. The highest infection rate was found to be in summer and this may be a factor responsible for lowering snail density in this season.
