Is there a trick for identifying Cepaea hortensis from Cepaea nemoralis? They look so simular, I can't figure out what to look for.  |

Hortensis have a dark lip to their shell and nemoralis don't

Thanks Sarah, I hope you got that right too ;D
I plan to be hunting for...well...one of the two anyway when I get to Scotland. And when I realized how simular they are, I thought I better have an ID trick up my sleeve.
Just to be sure I understood, that means the hortensis has that black line, or lines sometimes. But the nemoralis is solid colored?

these are mine and although they are all solid yellow, you can see some have a dark lip which are hortensis

It's still a little difficult to tell in that picture, but I think I am starting to see it. I really appreciate you doing this for me, they are one of my absolute favorites. Yours are darling. ;D

hortensis are usually about 20mm shell width, with a circular shell with a white lip. they vary much less in colour then nemoralis, usually having a yellow shell or yellow with stripes.
nemoralis have bigger shells (around 25mm) which are less circular and have a dark lip. they vary greatly in shell and body colour.
hope this helps.

It's also worth mentioning that to be 100% sure you probably need to look at more than one snail in a colony, because apparently sometimes there are specimens with the lip colour the other way round  |

I know but if shes thinking of collecting some then, she may pick up some young ones, but none of the young ones have formed the dark lip so she may think they are one species when they are the other, thats all

generally when talking about how to identify a species one refers to the adult specimens  |

ok ok, I got an idea  When I collect the snails, I will collect the "looks" I want. I am after a yellow pair and a red pair, once I find them (way way from now, this summer, bah its hard to wait) I will post pictures and let you guys help me from there. Sound good? I guess I run the risk of collecting different species, but at least that solves the ID'ing young snails problem. |
