Green Snake: (Opheodrys
vernalis) This is the most tragic and heart breaking snake
story of all.
These beautiful little snakes were quite common all across the state not too
long ago. However, because of the massive use of pesticides in the last few
decades their numbers have been decimated! Adults only grow to about 15-20
inches long and they eat nothing but soft-bodied Insects. (Caterpillars,
Spiders, Crickets and small Grasshoppers are about the only thing they consume)
There
are still isolated colonies of these snakes still barely hanging on in scattered
areas where the poisonous vapors have not yet wiped them out. I've only seen
them in the glacial hills region of Pope County, but had to travel to the
prairie highlands of north eastern South Dakota to find a thriving population.
(And the locals there say they don't see nearly as many as they used to)
Green
Snakes are extremely hard to see in the grassy meadows where they live. And
they
are fast moving little snakes, too being extremely hard to catch! They
lay 3-15
eggs in the early summer. They are only 4-5 inches long upon
hatching and
brown in color. An odd thing happens after they die: Their bodies
gradually lose
the green coloration and turn blue! (I've seen this in specimens that
were
killed on busy roads and hiways.) Unfortunately, this is about the only
way
you'll ever see any of these tiny emerald
creatures.
Green Snakes should be the "Poster Child" of organic
farmers
and gardeners. If you still have these living jewels near you...be
proud! For it
is proof that your little corner of the world is still relatively clean
and
healthy.
We would really like to find thriving populations Anywhere in SW
Minnesota. During the Bio Survey 2006 one of these was found in a drift-fence in
Lyon County. (And the locals say they are still occasionally seen) So they are
still out there. Please...Watch for them! And let us know when you find one.
