Dear John,

Something tells me you're writing from Northampton, MA.

If my memory serves, does your species look like this:

If so there may be more to its sudden appearance than simply a change
in the weather; see item (4) at the URL above.

With an exceptionally rainy summer, there has been a proliferation of
amber snails (genus Succinea) in my area.  It has me wondering what
their shells are, exactly.  Do they employ any calcium, or is the
shell material solely conchillion, or some other organic material?

John
