Webbhelix multilineata (Say, 1821) Striped whitelip |
||||||
|
This species is also known as Helix multilineata, Mesodon multilineata,
Tridopsis multilineata, and Polygyra multilineata.
Baker has it in the genus Polygyra and lists a number of subspecies,
including P. multilineata rubra (which would include the snail in
the top two photos) and P. multilineata multilineata (which
is the shell in the bottom photo). Form rubra is about 3/4
inch in diameter, while the form multilineata is about an inch in
diameter. The photograph of the form rubra shown here was found in a hillside seep at Camp Dodge in Polk County, Iowa. The form multilineata shown below was found in a hillside seep at Whiterock Conservancy near Coon Rapids, Iowa. I did not find a live individual, only a shell. |

Hubricht shows the distribution of this species as sort of the mid to upper
Midwestern states, including Minnesota, Wisconsin, Missouri, Illinois, and
east to Ohio and western New York. It is found in most of the counties
in Iowa that have records.

The coloration on the shell of W. m. multilineata is much different from that of W. m. rubra.
