The [[scientific name]] is derived from the Celtic settlement [[Vindobona]], now known as [[Vienna]], the capital of Austria. This species was formerly assigned to the genus ''[[Cepaea]]''. However, DNA sequences revealed that this species is not closely related to ''Cepaea'', but belongs instead to the genus ''Caucasotachea''.<ref name="pmid26256642">{{cite journal |last1=Neiber |first1=M.T. |last2=Hausdorf |first2=B. |year=2015 |title=Molecular phylogeny reveals the polyphyly of the snail genus ''Cepaea'' (Gastropoda: Helicidae) |journal=Molecular Phylogenetics and Evolution |volume=93 |pages=143–149 |doi=10.1016/j.ympev.2015.07.022 |pmid=26256642 |bibcode=2015MolPE..93..143N }}</ref><ref>{{cite journal |last1=Neiber |first1=M.T. |last2=Sagorny |first2=C. |last3=Hausdorf |first3=B. |year=2016 |title=Increasing the number of molecular markers resolves the phylogenetic relationship of "''Cepaea''" ''vindobonensis'' (Pfeiffer 1828) with ''Caucasotachea'' Boettger 1909 (Gastropoda: Pulmonata: Helicidae) |journal=Journal of Zoological Systematics and Evolutionary Research |volume=54 |issue=1 |pages=40–45 |doi=10.1111/jzs.12116 |doi-access=free }}</ref><ref>{{cite WoRMS | id=1002170 | title = ''Caucasotachea vindobonensis'' (c.

==Description== The right-hand coiled, globular shell of ''C. vindobonensis'' is 17–21&nbsp;mm high and 20–25&nbsp;mm broad with 5.5–6 whorls.<ref name="Welter-Schultes">{{cite book |first1=F.W. |last1=Welter-Schultes |title= European non-marine molluscs, a guide for species identification: Bestimmungsbuch für europäische Land- und Süsswassermollusken|location=Göttingen |publisher=Planet Poster Editions |date=2012 |isbn=978-3-933922-75-5 |page =268 }}</ref> In adults, the [[Gastropod_shell#Parts_of_the_shell|umbilicus]] is completely covered. The [[Gastropod_shell#Parts_of_the_shell|lip]] is brown at its inner end becoming pale towards the [[Gastropod_shell#Parts_of_the_shell|suture]]; this distinguishes it from the conchological similar ''[[Cepaea hortensis]]'' (usually pure white lip) and ''[[Cepaea nemoralis]]'' (usually a dark brown lip), with which ''C. vindobonensis'' often co-occurs. Another difference is that the shell ''C. vindobonensis'' has fine growth ridges whereas those of ''Cepaea'' are smooth.<ref name="Kerney1979">{{cite book |last1=Kerney |first1=M.P. |last2=Cameron |first2=R.A.D. |title=A field guide to the land snails of Britain and north-west Europe |date=1979 |publisher=Collins |location=London |isbn=000219676X}}</ref> The shell is whitish or yellowish, with typically 5 brown stripes, of which the upper two are usually weak.

Introduced populations in the United States (New York State) have been known since 2015 and in Canada (Quebec) since 2020.<ref name="Hausdorf2021"/>

The original habitat of ''C. vindobonensis'' was most probably open forests in the Balkans, from where it spread over large parts of Central and Eastern Europe after the last glaciation.<ref name="Kajtoch"/> Nevertheless, it also dwells in several grassland habitats like meadows, steppe and ruderal areas, especially in the north of its distribution area. The highest vertical occurrence is about {{cvt|1600|m|-1}} asl in Southern Bulgaria.<ref name="Welter-Schultes"/>

==Life cycle== All the following information originates from a Greek study. <ref name="Staikou">{{cite journal | last1=Staikou |first1=A.E. | title = Aspects of life cycle, population dynamics, growth and secondary production of the pulmonate snail ''Cepaea vindobonensis'' (Férussac, 1821) in northern Greece. | journal = Journal of Molluscan Studies | volume = 64 | issue = 3 | pages = 297–308 | date = 1998 | doi = 10.1093/mollus/64.3.297 | doi-access = free }}</ref> Because Greece is in the southernmost part of the distribution area, the phenology for this species might be quite different in the more northerly countries where it is found. ''Caucasotachea vindobonensis'' becomes mature after its second year and can reach a maximum life span of about 7 years. The reproductive period lasts from April to June, with a maximum in May. Each year, adults lay about 50 eggs, about 3&nbsp;mm in diameter, and the juveniles hatch out after 18 days. During hot summer days, these snails rest attached to leaves or the stems of tall plants. Hibernation commences at the end of October to the beginning of November, and the snails come out of hibernation in March.
