Yes, they look like they are

Yes, they look like they are mating. They are hermaphrodites,of course. And body colour also varies as you observed. Not sure though whether this is linked to shell colour genes. The almost black snail is in fact a yellow with 5 bands that are spread.

Take a look at www.evolutionmegalab.org for more about Cepaea genetics and evolution.

Thanks for the comment. I’ll give the reference some thought.
