Morphology. Medium-sized snail (shell up to 20 mm high). Shell is usually brown, apex is pointed, and animal itself is yellow, or green, with black spots. For more details see Welter-Schultes (2012: 53, figure in the middle of the page).

Distribution and ecology. Palearctic species up to 2700 m.a.s.l, in Serbia up to 800 m. a.s.l. Prefers smaller stagnant and slow-flowing waters, with impacts of groundwaters, on a sandy, gravel or rocky substrate. Can endure drought periods ( Welter-Schultes 2012). One of the most common freshwater snails in Serbia. It was recorded in a wide variety of habitats, including the Danube, Sava, Drina, Jadar, Zapadna Morava, Južna Morava, Temska, Visočica, Toplica, Mlava, Trešnjica and Zamna Rivers , streams on Fruška Gora Mtn., Zasavica Wetland, ponds near the Ludaš Lake etc.

Other remarks. Shell morphology is fairly constant, yet in some cases, it can be misidentified as Ampullaceana balthica ( Glöer 2019) . The taxonomy is not fully resolved yet (MolluscaBase 2021). On the IUCN Red List it has been assessed as LC ( von Proschwitz 2011 a).
