The first record the Limnia unguicornis (Diptera, Sciomyzidae) parasites on a vulnerable pulmonate land snail, Vertigo moulinsiana (Gastropoda: Eupulmonata: Vertiginidae) and a literature review on Limnia species.

The literature about mollusc-parasite interactions is focused on species affecting human health, such as trematodes on freshwater snails as intermediate hosts. Far less attention has been paid to parasite-snail interactions in terrestrial habitats. Here we present the first observation of a sciomyzid larva of Limnia unguicornis, parasitizing a vulnerable, tiny air-breading snail, Vertigo moulinsiana (strictly protected by Polish law).

Experimental evidence for snails dispersing tardigrades based on Milnesium inceptum and Cepaea nemoralis species.

Dispersal abilities in animals contribute to their local genetic variability and species persistence. However, the mechanisms facilitating a short-distance migration of small organisms remain underexplored. In this study we experimentally tested the role of land snails for a fine-scale transmission of tardigrades.
