Hairy Snail

Trochulus hispidus

This record describes Trochulus hispidus (species). Recorded family: Hygromiidae. Recorded order: Pulmonata.

Identification and Appearance

Shell 6 mm. The hairs on the shell wear off, but can usually be seen inside the umbilicus, which is quite well defined in this species. It is relatively flat, lacking a noticeable spire. Recent taxonomic changes have concluded that Trochulus sericeus is in fact the same species as T. hispidus . Ashfordia granulata is the other hairy snail in the region. This has a smaller umbilicus and is more conical in shape. Unless identified by a recognised expert, a photo is required. If the photo doesn't show the key ID features then in the comments box describe the size and identifying characters you have observed. Widespread and common throughout most of Britain.

About Pulmonata: the wider group

Order-level background for Pulmonata, the group containing Trochulus hispidus. 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.

Recorded sources for this group: FAO, agricultural pest management, gastropod research. Imported estimates may describe particular regions or reporting periods.
