Geographic Range [top]

Range Description:This holarctic species is distributed widely through the Northern hemisphere, in Europe Asia and north America, reaching southern limits in north Africa, Lebanon. It also recorded as an introduction in Australia and New Zealand. The status of the records from Venezuela needs investigation, as these may be introduced as well.

Within Europe the species has a widespread distribution, occurring in all European countries.  Fauna Europaea (Bank et al. 2006) lists the species from Norway, Sweden, Denmark (mainland), Faroe Is. (Denmark), Finland, Estonia, Latvia, Lithuania, Kalingrad region (Russia), Poland, Republic of Ireland (Eire), Great Britain (UK), Channel Islands (UK), Northern Ireland (UK), Netherlands, Belgium, Luxembourg, France (mainland), Germany, Switzerland, Austria, Czech Republic, Slovakia, Hungary, Italy (mainland), Bulgaria, Romania, Spain (mainland), Portugal (mainland), Albania, the former Yugoslav Republic of Macedonia, Slovenia, Montenegro, Reported from Croatia, Ukraine, Greece (including Andikíthira Island, Evvia Island, Ionian Islands, Samothráki Island, Northern Sporades Islands, Thásos Island). The species also occurs in south-west Asia (Syria, Lebanon, Jordan, Turkey and Israel) where Lebanon marks the southern limit of the species' distribution in this region.

A widespread species distributed in Asia (central, north and south and southeast), it has been recorded in India, Iran (Khuzestan Province, Glöer & Pesic, 2012) and Turkey. The Aammiq wetland in Lebanon provides good conditions for Lymnaea stagnalis (Bossneck, 2010). The species was reported by Schütt (1983) from the Syrian part of the Orontes drainage system, but does not extend to Israel.
