Pseudosuccinea columella, common name the "American ribbed fluke snail", is a species of air-breathing freshwater snail, an aquatic pulmonate gastropod mollusk in the family Lymnaeidae, the pond snails.

This snail is an intermediate host for Fasciola hepatica, the liver fluke, a parasite of livestock, especially sheep.[6]



Pseudosuccinea columella is native to North America.[7] and Europe.[8] The indigenous distribution of Pseudosuccinea columella reaches from New Brunswick and south Manitoba throughout the eastern USA to Central and South America.[9]

The exact type locality for this species is unknown, but it is somewhere in the Philadelphia area, USA.[10]


This snail has been introduced to Australia[7] and Europe.[11]

The non-indigenous distribution of Pseudosuccinea columella includes:



The shell quite closely resembles shells in the genus Succinea, which belongs to a different family.

The shell of Pseudosuccinea columella is horny brown, thin, translucent, fragile and very finely striated. The apex is pointed. The shell has 3.5-4 weakly convex whorls with a shallow suture. The last whorl predominates. The aperture is ovate. The upper palatal margin descends steeply. The columellar margin is reflected only at its upper section; the lower columellar margin sharp and straight.[9]

The width of the shell is 8–13 mm. The height of the shell is 15–20 mm.[9]

The animal is dusky with whitish spots. The eyes are small and black and are located at the inner base of the tentacles.[9]

The haploid number of chromosomes is 18 (n=18).[16]


In North America, Pseudosuccinea columella lives in stagnant waters, at the edges of lakes, ponds, muddy and sluggish streams, among lily pads and reeds on sticks and mud.[9]

In Europe it occurs predominantly in greenhouses, but also sometimes in outdoor habitats (Austria, Hungary).[9] It needs warm water and does not survive Central European winter temperatures.[9] It is also found above the water on floating leaves of aquatic plants; in northern Greece it was found in a spring near a road.[9]
