Lapidary Snail
Helicigona lapicida
This record describes Helicigona lapicida (species). Recorded family: Helicidae. Recorded order: Pulmonata.
Identification and Appearance
The shell of this species is approximately 20 mm in maximum dimension. The lapidary snail has got a characteristically lens-shaped shell with a clearly visible keel. The shell has a grey-brown colour with blurred red-brown spots. Because of the shell form the aperture is very oblique; the lip is distinct and whitish. It is set off the shell surface. The umbilicus is wide and open. As this species is uncommon in our area, a photo is normally required. Shady rocks and walls (especially those overgrown with ivy) and tree trunks, especially Beech, Hornbeam and Sycamore. The characteristic form of its shell enables the lapidary snail to withdraw into crevices in rock or bark during dryness. Widespread in the southern half of Britain.

About Pulmonata: the wider group
Order-level background for Pulmonata, the group containing Helicigona lapicida. Species-specific details appear above.
Group overview
Pulmonata includes terrestrial and freshwater snails and slugs with ~30,000 described species. The giant African land snail (Lissachatina fulica) can reach 20cm and is one of the most invasive species globally.
Ecological role of the group
Terrestrial gastropods are important decomposers and calcium recyclers in forest ecosystems. They are also critical food sources for birds, hedgehogs, and beetles. Many species are hermaphrodites, possessing both male and female reproductive organs.
Economic and practical significance of the group
Slugs and snails cause billions in crop damage worldwide. The global molluscicide market was valued at $800 million in 2023. Conversely, edible snails (escargot) support a global industry worth over $4 billion annually.
