Brown-lipped Snail (Cepaea nemoralis)

OTHER NAMES: Grove Snail
Latin Etymology: Cepaea ("of the garden") nemoralis ("of the woods")
Adult Brown-lipped Snail (Cepaea nemoralis) at Geddington, Northants - May 2029

Featured Subspecies: ?
Weight: ?  /  Width: 18-25mm
NO UK STATUS IUCN Red List: Least Concern

Similar to it's close relation the White-lipped snail in many ways, the Brown-lipped snail can indeed be differentiated by the colour of the band around the opening of it's shell, here seem to be brown, although even this is no entirely reliable.  The colour variety seen in the picture is a more woodland adapted varient due to it's brown colouration, but comes in a wide variety of forms from yellow to the classic yellow and black spirals.  Unlike the White-lipped, this species has established itself in the Americas.

White-lipped Snail (Cepaea hortensis)

OTHER NAMES: Garden Banded Snail
Latin Etymology: Cepaea ("of the garden") hortensis ("of the garden")
Adult White-lipped Snail (Cepaea hortensis) at Trevose Head, Cornwall - June 2011

Featured Subspecies: ?
Weight: ?  /  Width: 2.5cm
NO UK STATUS IUCN Red List: Not Yet Evaluated 

One of the other most common snails, and in my opinion the most beautiful found in the UK.  It and it's close relation the brown-lipped snail are both highly variable in shell pattern, with it being a noted example of habitat based natural selection, with the entirely bright yellow snails being more common in open grassland while the darker and more banded specimens find more success in woodland where their shells act as better camoflage.
