Hi Bart, looks like a hairy one: Helicodonta obvoluta? Greetings, Eric Edited by eklans on 20-11-2020 15:00 |

Hi Eric, thank you for your response. I came across this species while trying to sort out what lives in my backyard. However, according to the information I found on the internet, Helicodonta obvoluta lives only in SW Poland, in the mountains and it inhabits forests. It doesn’t match where I found it at all (NW Poland, lowland, a dry backyard). |

Hi Bart, yes - Helicodonta obvoluta is associated with woodland (that's why it's common in my garden). What about Trochulus hispidus (Trichia hispida)? This one (ślimak kosmaty) is reported from Poland, but this one seems to be not as flat as the one from your image. Greetings, Eric |

Thanks Eric for your suggestion, but I have no clue. I found another picture, I think it's the same species.

Hi Bart, that looks good for Trochulus hispidus (though I'm not an expert for the snails). If you look at https://en.wikipe...s_hispidus you may find, that it resemble yours quite well - and the hairs are worn off, too - as do mine  .Greetings, Eric |

It is T. hispidus. It is a very "plastic" species looking quite differently on various stands. The DNA analyses also showed, that more hairy population with higher shell called formerly T. sericeus is nothing more than a form of T, hispidus. Time to time both forms can live together. Libor |
