Dear Conch-Lers,

This past week I was visiting family in North Vancouver, BC  (Canada)
and was quite surprised by the numerous colonies of Cepea nemoralis in
parks, gardens, etc.  The shells are rather varied in color and banding
including a color form with a bright orange base color.  I'm left with
some questions that I hope can be answered here:

Does anyone know when this snail first showed up on the West Coast?

How wide of a distribution does it have?

Does an orange color form (both banded and unbanded) turn up elsewhere?

Thanks in advance,
