Photo of the day (37): Helicopsis striata

Helicopsis striata is an interesting species. This land snail live in glacial loess steppe habitats. It lives on such habitats since ice ages. Steppes are fragmented and changed by people but this species can not live elsewhere. This means that it is a glacial relict.

It is extinct in France, it is critically endangered in Germany, in Austria, in the Czech Republic and in Slovakia. It is endangered in Poland. But it lives in large areas in Europe and it is considered as Least Concern species.

The width of the shell of this specimen is 7.5 mm and the height of the shell is 5 mm.
