Pseudosuccinea columella is native to North America.[5] and Europe.[6] The indigenous distribution of Pseudosuccinea columella reaches from New Brunswick and south Manitoba throughout the eastern US to Central and South America.[7]
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.[7]
The width of the shell is 8–13mm. The height of the shell is 15–20mm.[7]

The animal is dusky with whitish spots. The eyes are small and black and are located at the inner base of the tentacles.[7]
The haploid number of chromosomes is 18 (n=18).[17]
Habitat
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.[7]
In Europe it occurs predominantly in greenhouses, but also sometimes in outdoor habitats (Austria, Hungary).[7] It needs warm water and does not survive Central European winter temperatures.[7] 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.[7]
Parasites
Parasites of Pseudosuccinea columella include:
In North America, Pseudosuccinea columella is major intermediate host of Fasciola hepatica.[4][18]
