The beehive ( Spermodea lamellata ) is a terrestrial snail species from the family of grass snails (Valloniidae); the family belongs to the subordination of land snails (Stylommatophora).

features

The housing is spherical with a low-conical apex. It measures approximately 2 × 2 mm and has 5.5 to 6 whorls. The turns are rounded, and the navel is narrow and deep. The surface is provided with pronounced ribs that are almost perpendicular to the winding axis. The ribs are outgrowths of the organic periostracum and can therefore only be seen on fresh specimens. They are missing from weathered specimens. The ribs make the case appear slightly iridescent. It is colored honey yellow to golden brown. The mouth is rounded to oval and the edge of the mouth is not thickened, rather thin and fragile.

Occurrence, way of life and distribution

The beehive lives in old deciduous and mixed deciduous forests in moderately moist soil litter. The distribution area can be described as north-west European-Atlantic. It extends from Portugal to the British Isles and in the northeast to northeast Poland. In the north, the distribution area extends to northern Norway.

Systematics

The beehive is the type of the genus Spermodea Westerlund, 1903. The German trivial name comes from the similarity of the housing with old beehives.
