That's interesting. How & why did they get up to his roof? I suppose
hatchlings are small enough to be wind blown.

Most "larger" snails seem to take at least a few years to become adults, so
they have to survive the winter. As a matter of fact some, at least
Anguispira, require a cold period before they can reproduce. I collect even
in the dead of the winter & I have seen dormant snails of all sizes under
rotting trunks above frozen soil.
