Desmoulin’s whorl snail
1 February 2010
This tiny snail, not more than 3mm tall, is found in south and south eastern England around the edges of ponds, streams and rivers. In the warmer months it lives on the leaves of tall wetland plants when it is easiest to see. Desmoulin's Whorl snail is a priority species on the UK Biodiversity Action Plan.

Latin name: Vertigo moulinsiana
Population numbers: No accurate figures exist. Though never a common species it is thought its numbers have reduced recently.
Where to see and when: The Desmoulin’s Whorl Snail is found only in southern and south-eastern England in a band from Dorset and the Isle of Wight to Norfolk. It can be seen on a number of protected as well as non-protected sites. The snails are most visible in the warmer months, but its small size makes it difficult to spot.
What’s being done: Conservationists are undertaking detailed surveys to try and get a more accurate idea of their population in southern England. Conservation work has concentrated on preserving its preferred habitat from the effects of agriculture, drainage and development schemes, and pollution.
