Vallonia pulchella

Compared to Vallonia costata, the aperture is not very oblique, and the lip is weaker than in that species.

This species occurs in several countries and islands, including: Europe: America: The size of the egg is 0.5 mm.

[9] In this species some parental care was observed: apparently the eggs were cleaned of fungi.

[9] Parental care is very rare in gastropods in general and has otherwise been observed only in the genus Libera.

V. pulchella thrives best in habitats characterized by relatively moist and conductive soil, large soil aggregates, low temperatures at 0-10 cm depth, a well-developed litter layer, low light level, and low numbers of plants which change shape in response to humidity and/or light levels.
