| Overwintering habits of the land snail Vertigo angustior (Mollusca) During a mollusc survey in 2004 en 2005 in the province of Zuid-Holland special attention was paid to Vertigo angustior. The species was observed overwintering in large groups, up to hundreds of specimens together, between mosses (especially Brachythecium rutabulum (Hedw.) Schimp.) in small patches of poplar forest (Populus nigra and Populus alba) in the old dunes. As far as we know, this gregarious behaviour is described here for the first time. Many of the snails were found in a position where they had incorporated a moss leaf into the epiphragm closing the shell’s aperture, thereby achoring themselves to the vegetation, possibly for stability. |

| In 2005 werd onverwachts de zeggekorfslak op twee plaatsen in Zuid-Holland aangetroffen (Boesveld, 2005). De zeggekorfslak staat op de Habitatrichtlijn en geniet wettelijke bescherming. Om hieraan invulling te kunnen geven is het voor de provincie Zuid-Holland van belang om goede informatie over de verspreiding, biotoopkeuze en beheer van deze soort te hebben. In 2006 heeft de provincie daarom aan EIS-Nederland de opdracht gegeven om het voorkomen van de soort in de provincie in kaart te brengen. Tijdens het in 2006 uitgevoerde veldwerk is V. moulinsiana in totaal in negen (deel)gebieden aangetroffen: Nieuwkoopse plassen, Kagerplassen, Braassemermeer en Wijde Aa, Rotte, Hennipsloot en Lange Vaart, Vlietlanden, Kinderdijk, Groote- of Achterwaterschap en... |

| The distribution of the land snails of the province of Zeeland, with special emphasis on Vertigo angustior (Mollusca: Gastropoda) In 2005 the land snail fauna of the coast of the province of Zeeland was mapped. In total 98 soil and litter samples were taken and on 54 localities records were gathered on sight. In total 55 land snail species were found, eight of which are on the Dutch red list. Five species, Helicodiscus singleyanus, Boetgerilla pallens, Cernuella cisalpina, Paralaoma servilis and Balea heydeni, were recorded for the first time in the province of Zeeland. Vertigo angustior was rediscovered on most of the known sites and was recorded at several new sites. |
