A small tightly-coiled snail 2.2-2.6mm in diameter. The shell is glassy and transparent but frequently appears 'milky'. The aperture is moon-shaped and without teeth.

Vitrea crystalina (Common Crystal Snail) is similar but can be separated, being larger (3-4mm) and having the last whorl widen to the mouth. It also tends to be found in wetter habitats.

Deciduous woodlands, grasslands, pastures, hedgerows and rocky areas. Prefers calcareous soil and is tolerant of drier conditions.

All year.

Common and widespread across all of the UK.

Probably reasonably common but under-recorded due to its small size.
