Hi @ll, I have got a new page on leaf snails ( Hygromiidae) and bush snails ( Bradybaenidae).  Common hair snail (Trichia hispida, Hygromiidae) and bush snail (Fruticicola fruticum, Bradybaenidae). Picture: Robert NordsieckThere are, of course, many species missing, because I had no pictures of them, but it is a beginning. Kind regards Robert |

Hi there, I have to admit that the term "leaf snails" is a literal translation from German by lack of an English colloquial expression for this family. In German they are called "Laubschnecken", which means leaf snails. If anyone of you knows the correct English name, let me know. Bumblebee: I would gladly give you this snail, but I do not have it, as I love more to photograph snails in their original environment, than to catch them and put them into a terrarium. But Fruticicola fruticum should also occur in Sweden, at least in the Southern part, doesn't it? Kind regards Robert Thanks very much for the kind remarks on my homepage |

I use to see Fruticicola fruticum almost everytime I visit the leaf forrests of nortwestern skåne(southern sweden) in summertime. I think they could be hard to keep as pets though as they live in the same environment as Arianta arbosturum who need quite cool temperatures and can be quite hard to keep indoors during the warmer part of summer.

I recently got some Fruticicola from Sweden, I was quite worried about climate change (mediterranean climate, Thyrrenian sea -totally different)...
Till now, they seem quite active, and eager to eat lettuce, large amount of it. It seems to be they preferred food, until now.
Yet I let them most of the time resting, outdoors in a shady cool (the cooler I can afford) place in the garden; and a wet cloth is wrapped around their box, so I can water it (I do that quite often) and keep it a bit cooler.
I would try some of them spending the warmer peak (around now) in the refrigerator (around 6 C°) after having entered dormancy, to be awakened when the summer peak is past.
Resting at outdoor temperatures seems quite ok, but I noticed some "retraction", in transparence: perhaps higher temperatures dry out their bodies more fastly (and perhaps I should mist more often), or they metabolize more quickly.
So, at least until kept at current temperatures, I awake them from time to time, in order to feed them; then letting them re-enter dormancy.
Robert, I noticed that your featured (Austrian?) snail is yellow and has a rounded last whorl and low spire; while these swedish ones are all more or less high-spired, some with some hints of despiralization, and a deep pink-orange in colour.
I see diverse, even a brown specimen on your interesting page. Do you know if both these variations are linked to populations/geographic races, or simply part of global polymorphism of the species, as a whole?
Kind Regards,
fabrizio

Hi there, fabrizio: I am sorry, I did not mention that on the page: The Fruticicola snails all were from Freiburg in Southwestern Germany, found at the same place, about a hundred metres apart. So in this case that would be local polymorphism. I think I recall that I read in Falkner et al. (1990), that F. fruticum is a very polymorph species. Kind regards Robert Attachments:

Sorry Robert, I was recalling about your presentation page I read some years ago, that you had worked in Austria for a long time, so I supposed the snails were from there So there is a high polymorphism in F. fruticum... but the yellow one, is actually the more abundant "morph" in that Freiburg area, or are the different colours more or less evenly distributed? _The ones I got from Sweden are all very similar each oithers, both as the colour as well as the shell shape. Perhaps different populations could exhibit different degree of polymorphism? -I read, there is a Russian study on the Web about Fruticicola polimorphism in steppae, related to habitat and to anthropic effects ( Ecological and genetic characteristics of the distribution of Bradybaena fruticum Mull. (mollusca, gastropoda, pulmonata) in a forest-steppe landscape), but sadly I couldn't acceed to it... Kind Regards, fabrizio |

@ fabrizio: I have indeed lived in Vienna for eight years, so the homepage is still called weichtiere.at. But I am not there any more since the beginning of last year, which was when I had a period where I took many photos and wrote numerous pages.
Truly I cannot say, which morph is most frequent in Fruticicola. I am afraid, probably there is not as much known, as in Cepaea.
I would think, though, that the polymorphism might have to do with the type of environment the snail lives in, bushes or tree trunks or places with little vegetation. So the overall selection might disfavour some morphs but favour the entire species.
Kind regards
Robert

Kind regards Robert Thanks very much for the kind remarks on my homepage Wow, it's been ages since I last visited the forum, it's nice to be back and see it's still active. I really like your homepages, Robert. Informative and nice photos as well. I hope to see more from you in the future. Fruticicola fruticum can indeed be found in Sweden and they are quite common even where I live, East Middle Sweden. There are even reports of an isolated populations as high as Norrbotten. gnm.se/upload/GNM/PDF/arstryck/2005moll.pdfI haven't found any yellow variations yet (or any other), but I intend to do a more intense search now when we finally have got some rain. My son is keeping a few as pets, under my supervision and it's a small experiment on how they thrive in captivity. So far so good. They are kept in room temperature, +20ºC and the substrate is moist sphagnum moss. They feed on nettle, Symphytum ×uplandicum (Russian Comfrey?) and they have also munched on some sliced carrot. Take care and have a great Sunday everyone! Best wishes Fredrik |

Hello Fredrik Welcome back on Petsnails! All of the Fruticicola are doing well, I let them to rest for some days, two days ago I tried to re-wake up them, sprayed and all of them became soon quite active and lively, greedly feeding upon common salade (their preferred food), carrot slices and sliced apple! I'm trying to keep them in the coolest available place, with a wet cloth wrapped around, and temperatures reached at most 27 C°, in the afternoon of the warmer day since now. -So Fedrik, (almost) all of the local Fruticicola in your surrounding areas are orange and more or less conical in shape, it would seem. Surely you're right Robert, and there is little study about geographic/ecology related morphs... -Perhaps a global surveying project, as the one being carried upon Cepaea colouration, would be useful for Fruticicola, too... -Within our limited scopes, couldn't we do start something similar by ourselves? -If members from several countries, where Fruticicola snails do live, would begin to post pictures of their local specimens and the kind of habitat they were found within, that could be surely better than nothing, I believe _Could you suggest how to organize that, in a functioning way? Kind Regards, fabrizio |

It would certainly be possible, especially in this international forum, to determine different types of Fruticicola in our respective countries. If I had access to a natural history museum (which I don't as I am in medical rehabilitation), I would like to check on the Archiv für Molluskenkunde of the DMG, what it says about Fruticicola fruticum. Actually it is me who don't know enough about F. fruticum to say something educated about the frequence of their morphs... I am looking forward to be able to do that again (it was nice to have that in Vienna, where there is a very good Molluscan collection)... Kind regards Robert PS: Thanks, Fredrik, for your friendly words! I am glad to hear that my pages are even read in Sweden PPS: By the way, your avatar is not working  |

Thank you Robert, and first of all I wish you to be soon out of medical rehabilitation, I didn't knew about that and I'm sorry to hear that  ... Then, any data could be useful or work as a "basis", members from dfferent countries/areas could loosely update and integrate, by making local observations. If that begins to work, I believe it will widspread to more people and arouse more interest Kind Regards (and my Best wishes for full healing soon!), fabrizio |

Hi there,
thank you very much for your good wishes. I am afraid, it will need some time, but I'll try to give as much information, as I can.
By the way, somehow I still cannot start the Mondo Gasteropodi forum. I received the registration email, but I cannot confirm it and (with may laptop, as Internet is down here) the forum will not take the login.
I am somewhat unsure what to do...
Kind regards
Robert

Very sorry Robert... I am not an "expert" in technical problems, so I'll ask to my -more able- staff members; hope all will be settled soon! -Very good if a sort of -small scoped too, it doesn't matter- " Fruticicola fruticum eco/morphological survey", or the like, could be started by ourselves! But still I would recommend you not to make any unnecessary effort, until not fully healed. -Sadly we could add just a little to such "survey", as the species is only very marginally present in Italy; yet at least a member from North-eastern Italy saw them near his home, and so another (new) member from Switzerland... even a single contribution, from a "new" locality could be somewhat useful, I guess Kind Regards, fabrizio |
