On aquatic plants around pond edge, about 3/4 inch, the others I saw were in the water instead of on plants above water, but saw maybe 4 plus others
this water snail was about 3 inches under the water in a pond. The snail is about 1 inch wide and 1 inch tall.

The Neotaenioglossa is an taxonomic name for a large group of mostly sea snails. The name was originally created by Haller in 1882. Ponder and Warén (1988), and Marquet (1997), assigned this name to the superorder Caenogastropoda. ITIS considers the order Neotaenioglossa to be a synonym of Cerithioidea Férussac, 1819 .
